21/07/2023 ….. A week spent wandering – Part 1

Dragon Rocks NR, Numerous days, Road Trip, Western Australian Orchids

Our one week’s holiday is upon us, and we had planned a trip to Albany, however plans do change and so we are actually heading up to Perth first, to see the Lightscape Show in Kings Park.

Today we make our way to Pingelly, where we have booked a room in the newly re-opened Exchange Tavern. We will of course make a few stops to check for orchids. the first stop being in the Dragon Rocks Nature Reserve. Our plan here was to check some previously found orchids to see if we have timed their flowering. Unfortunately, we were a tad early, plus it was a very overcast day, so no sunshine to encourage the orchids to open. From the leaf structure and the spotted markings to the buds we believe them to be the Eastern Queen of Sheba (Thelymitra speciosa) which flowers from late June to September, over a range from the Stirling Range to Condingup.

We also found some Hare orchids (Leporella fimbriata) still flowering and a few past their prime greenhoods. They are most likely some Mallee banded greenhoods (Pterostylis arbuscula) due to their small stature.

**Short statured Mallee banded greenhood**

Time is getting away, so we move onward. We head west and make our next stop near the Pingaring Nature Reserve. We make our way up the track to the granite rock which is another one which is used as a water catchment. It was a nice walk however the only orchids found were some Hairy-stemmed snail orchids (Pterostylis setulosa) which is a common inland species. Still a new species for the day so not disappointed. This may prove a great location for later in the season.

**Petals and dorsal sepal fused to form hood over column.**

Nearly 2pm so again we move on. Still heading west, we decide to check out Jilakin Rock, which we have planned to do many times before but have never had the time. We pull into the bay on the roadside and as usual it looks pretty rundown and weedy, which has put us off before. This time though using Google Maps we note a track that heads around the rock nearer the lake. Here we come across an abandoned gravel/sand pit area, so we pull up and go exploring. First orchid found is another Hairy-stemmed snail orchid, with more of them found further afield as well.

This location though turns up more than just snail orchids. We find many Blue beard (Pheladenia deformis) flowering all over the location. These bright orchids are always a pleasure to find, as they always provide the chance of finding a white variety. No such luck this time though. Their season is from late May to October, and they range from the Murchison to Israelite Bay. They are also referred to as the Blue fairy orchid by some references.

Now for the hard part. Trying to identify the many wispy type of spider orchids found. Using the ‘Explore Your Area” function of Atlas of Living Australia website there are a few possibilities which does help to narrow it down. First up is the Chameleon orchid (Caladenia dimidia) which is a variably coloured orchid found flowering from July to early October, between Paynes Find and Scaddan.

Just thought I would post a video to show how the wind makes getting great photos of these small spider orchid very difficult.

Hold still please!!!!!!!!!!!!!!!!!!!

Other orchids do not seem to fit the descriptions in my references so I will post some pics of them and please let me know your thoughts on the identification.

Just after 3pm so we move on as we need to get to Pingelly for our planned overnight stop at the Exchange Tavern. We enjoy a wonderful pub meal, play video games on a sit-down console in the TV room and settle in for a comfortable night’s sleep. A great finish to our first day.

22/10/2022 ….. Hop out to Helms

Esperance, Helms Arboretum, Western Australian Orchids

Breakfast enjoyed at the Esperance Bird and Animal Park with my sister Lorraine, brother in-law Ken and Tim, Tian and kids. It was then time to show L&K the Helms Arboretum orchids. Well, the one’s flowering in late October that is.

It has been raining so the orchids are covered in drops of water which makes for some great pictures. First up we find the small but colourful Elegant donkey orchid (Diuris concinna) which flowers from September to early December between Bremer Bay and Cap Arid.

Forward projecting lateral sepals hidden under labellum
Tapering dorsal sepal
Up to 400mm in height
Up to 5 flowers per orchid
Covered in water droplets

Also, very excited to find some orchids without any colouring other than yellow. These are likely to be lutea or hypochromic versions of the Elegant donkey orchid, as the visually similar Little Esperance bee orchid is listed as a very rare orchid, so is unlikely to be found at Helms.

Tapered dorsal sepal
Elongated petals
Forward projecting lateral sepals hidden under labellum.
Up to 5 flowers per orchid

Due to the damp and overcast weather the sun orchids are barely open. Firstly, the Leopard orchid (Thelymitra benthamiana) is found. These orchids flower from September to November between Northampton and Israelite Bay. Next is most likely the Scented sun orchid, however as I overlooked taking photos of the leaf, positive ID will not be possible.

Other random orchids found include the Purple enamel orchid (Elythranthera brunonis) which flowers August to early November between Kalbarri and Israelite Bay; the Rattle beaks (Lyperanthus serratus) which flower September to November between Perth and Israelite Bay; and the White fairy orchid (Caladenia marginata) which flowers late September to November between Juien Bay and you guessed it, Israelite Bay.

Then last but definitely not least, we locate some spider orchids. The Esperance white spider orchid (Caladenia longicauda subsp. crassa) is still found in fairly good numbers, given they are recorded as flowering August to early October. The other orchid is the Esperance king spider orchid (Caladenia decora) which flowers mid-August to October. Both orchids are recorded as occurring from Bremer Bay to as far east as Israelite Bay and Cape Arid respectively.

With at least eight species located it turned out to be quite a successful hunt. Oh, I would love for the yellow orchids to be the Little Esperance bee orchid, however I would require a better person than myself to name them that. However even if they are just a single-coloured variety of D. concinna, that will still be fine. Tomorrow, we head north.

08/10/2022 & 09/10/2022 ….. Jacup Jewels

Numerous days, Road Trip, Western Australian Orchids

Upon leaving the Jerramungup burnt are we head east looking for somewhere to park up for the night. We make it about 35kms when we pull into the Jacup Highway Park at the Fitzgerald River crossing. This will do, so we set up the camper and I do my best to drive over a log in my Ford Falcon, not the greatest idea 🙂 I’ve had.

Now we still have the late afternoon to go orchid hunting. As per our previous visit to this location, we are not disappointed. First, we find the Green spider/Fringed mantis orchid (Caladenia falcata) flowering in isolation and in small groups over the entire area we checked out.

Calli extend to mid lobe only
Clubbed sepals
Parent and hybrid child

As can be seen in the picture above the hybrid, Wheatbelt spider orchid (Caladenia x cala) was also found. It was amazing how many were actually found, as we usually find one or two only in each location.

Attractive hybrid
Red hockey stick shaped calli
Regularly found in twins
Standing up to 400mm in height
Long fringe segments to greenish-white, red-tipped labellum
Long pendulous lateral sepals
Another parent and hybrid child

And of course, we also found the other parent for the hybrid. The Stark white spider orchid (Caladenia longicauda subsp. eminens) occurs as far east as Ravensthorpe and grows in open woodlands so seems to fit the bill.

Broad labellum
Broad bases to lateral sepals
May be found in tight groups
Bright white in colour
Labellum yet to curl under

Next, we find the very special Lazy spider orchid (Caladenia multiclavia) which is recorded as occurring between Wongan Hills, Borden and Ravensthorpe. This unusual looking orchid is known for its upright petals and sepals plus the smooth striped labellum with a dense band of bristly headed calli.

Tied up with cobwebs
All sepals and petals held upright
Horizontally held flowers.

We also come across a mixture of other orchids but not in great numbers, so I will record then with only 1 pic each. Firstly, there is the ever-reliable Cowslip orchid (Caladenia flava subsp. flava) and Common mignonette orchid (Microtis media subsp. media). Both are common, widespread orchids. Then the more rarely found, without a recent summer fire, Red Beaks (Pyrorchis nigricans) is discovered with a nine-flower inflorescence. Finally, a pale coloured Pink candy orchid (Caladenia hirta subsp. rosea) and possibly a Ravensthorpe rufous greenhood (Pterostylis leptochila) yet to fully flower are found.

One orchid not expected was the Common dragon orchid (Caladenia barbarossa) which is found flowering between Bindoon and Munglinup. There are only 4 species of dragon orchids, and all are endemic to WA. Only 2 specimens found but still very happy.

Column overlooks the large major callus
Standing up to 300mm in height

Distinctive hairy labellum

However, one final orchid is found in decent numbers. The Drooping spider orchid (Caladenia radialis), is found flowering between Northampton and Ravensthorpe from August to October. The labellum can have smooth margins or tiny marginal teeth.

Drooping petals and lateral sepals
Dorsal sepal can be held erect.
Two distinct bands of calli

Back to camp due to the fading light.

We awake to a beautiful sunny morning, have breakfast then decide we will take some time this morning to complete a search down to the river. Fingers crossed for something new.

First up though I will post pictures of those orchids we come across that we also found in our afternoon search yesterday.

Now for the new findings of the location. The Short-sepaled spider orchid (Caladenia brevisura) is found between Jerramungup and Israelite Bay from August to October. Only one specimen found, and not the best picture, but a record non the less. Another sole specimen found was that of the Bee orchid (Diuris laxiflora) which flowers September to early November between Gingin and Esperance.

Blue sun orchids are found in good numbers closer to the river. Now identifying them is needed. As I am writing this account over 12mth later I am identifying them from pictures taken. Based on these I feel some to be Scented sun orchid (Thelymitra macrophylla) due to the broad leaf and large numerous flowers. Others though have thin leaves with fewer flowers, so are most likely the Shy sun orchid (Thelymitra graminea). Both are recorded as flowering in the Shires of Ravensthorpe and Jerramungup during the month of October.

It is 11am so we had better push on as we need to arrive home in Esperance today. One last stop is made at Kukenarup Memorial, where we enjoy a spot of lunch before one last exploration for orchids.

08/10/2022 ….. Burnt Jerramungup

Numerous days, Road Trip, Western Australian Orchids

OK so we finally arrive at the promised land. The burnt area near Jerramungup. We spend just short of 1hr walking around the burnt-out landscape and find the Red beaks as expected in good numbers, however the other orchids were few and far between. They are recorded below as usual.

Red beaks (Pyrorchis nigricans)

Habitat: Found between Shark and Israelite Bays, growing in sandy, sandy-clay and lateritic soils in forests, woodlands and scrublands. With rare exceptions, plants flower only in the season following a summer fire.

Season: August to October

Red beaks en-masse after the summer fire

Purple enamel orchid (Elythranthera brunonis)

Habitat: Found between Kalbarri and Israelite Bay, growing in sandy, sandy-clay and lateritic soils in forests, woodlands and scrublands.

Season: August to early November

Cowslip orchid (Caladenia flava subsp. flava)

Habitat: Found between Northampton and Israelite bay, growing in sandy, sandy-clay, lateritic and granitic soils in forests, woodlands and scrublands. In inland areas the subspecies is found in isolated populations on granite outcrops and rocky hills.

Season: July to early December

Blue china orchid (Cyanicula gemmata)

Habitat: Found between Kalbarri and Israelite Bay, growing in coastal heaths, open forest and mallee scrubs, on sandy to clay to gravelly loam soils.

Season: August to early November

Green spider / Fringed mantis orchid (Caladenia falcata)

Habitat: Found between Wongan Hills and Jerramungup, growing in woodlands and shrublands on sandy to clay loam soils.

Season: September & October

?? sun orchid (Thelymitra sp.)

Appear to be from the Sienna sun orchid complex due to the broad leaves.

Nearly 3pm and a bit deflated, we move on westwards looking for our overnight location.

08/10/2022 ….. Warperup East Nature Reserve

Nature Reserves, Numerous days, Road Trip, Warperup East NR, Western Australian Orchids

After leaving Ongerup, the plan was to drive to Jerramungup to check out a burnt-out area we spied on the drive to Albany on Monday, however as per usual we make an unscheduled stop at a new location for us. Warperup East Nature Reserve looked too good an opportunity to just drive by, so after less than 20kms into the drive we turn off, down Corackerup Road and pull over on the roadside to commence our exploration of this area. We spend a good 45mins here checking out various spots along the roadside and were very excited to find our first ever striped sun orchid along with other previously found species.

First orchids found were a couple from the green spider orchid complex. Now due to the calli extending past the mid-lobe of the labellum, I believe these to be the Small mantis orchid (Caladenia attingens subsp. gracillima) which is recorded as being found between Jerramungup (20ish kms to the east of current location) and Israelite Bay and flowers from August to early October, which covers off the date as well. Please correct me if I have wrongly identified the species.

Now for the highlight of this morning. We find many specimens of the beautiful Western azure sun orchid (Thelymitra occidentalis). This orchid is recorded as being common over its southern distribution, Cranbrook to Eyre, however as stated earlier it is our first time finding this orchid, so not common to us. They flower from September to November and can reach 400mm in height, plus may have up to 15 flowers per plant. A beautiful sight indeed.

In the middle of all these Azure sun orchids a Shy sun orchid (Thelymitra graminea) is found. A similar sized orchid though only half the numbers of flowers per plant. These orchids range from Perth to Esperance and flower in October and November.

A much smaller orchid from another genus is the next found. The Ruddy hood (Pterostylis perculta) was previously named after the town of Ongerup, prior to being formally named in 2015. These small orchids are found from the Stirling Range to Thomas River, east of Esperance. They are found growing in rocky soils during September through November.

The Purple enamel orchid (Elythranthera brunonis) is the final orchid we find flowering at this location. These orchids range from Kalbarri to Israelite Bay, flowering from August to early November.

We did actually find one other orchid; however, it is only in bud at this time. It appears to be an orchid from the Sienna sun orchid complex, due to the broad leaf.

Not a bad wing it stop I must say, especially given the find of the Western azure sun orchid. 5 species in total found flowering. Time now to move onto the burnt-out area near Jerramungup.

08/10/2022 ….. Ongerup walkabout

Numerous days, Road Trip, Western Australian Orchids

After not too cold a night we awake to a beautiful day in the Ongerup Gardens Caravan Park. After cereal for breakfast, we decide to go exploring the woodlands behind the caravan park. We take what we believe to be a rough track, but it peters out soon enough, so we go bush bashing in an attempt to find it again. We end up curving north and head up past the sporting complex. We cross Jaekel Steet and follow the track/s to the Yongergnow Malleefowl Centre, where we grab a coffee, for the walk back to the caravan park. The orchid count for such a good walk was a bit disappointing, however we did find some, so I will record them now.

Lazy spider orchid (Caladenia multiclavia)

Location: Borden to Ravensthorpe with rare populations northwards to Wongan Hills.

Habitat: Grows in woodland habitats, especially sheaok Allocasuarina species, on damp sheltered sites, often around rocky outcrops.

Season: September & October

Green spider (Fringed mantis) orchid (Caladenia falcata)

Location: Wongan Hills to Jerramungup

Habitat: Grows in a variety of woodland and shrubland habitats, on sandy to clay loam soils.

Season: September and October.

Cowslip orchid (Caladenia flava subsp. flava)

Location: Northampton to Israelite Bay

Habitat: Flowers in greater profusion after summer fire. Sand, laterite, granite. Coastal woodlands, winter-wet swamps, forest areas, granite outcrops.

Season: July to December

Purple enamel orchid (Elythranthera brunonis)

Location: Kalbarri to Israelite Bay

Habitat: Grows in a wide variety of habitats, including heaths, woodland, open forest and mallee scrubs.

Season: August to early November

Lemon-scented sun orchid (Thelymitra antennifera)

Location: Shark Bay to Israelite Bay

Habitat: Sand, clay, sandy loam. Seasonally moist flats, creeklines, granite outcrops.

Season: July to October

Frog greenhood (Pterostylis sargentii)

Location: Northampton and Grasspatch

Habitat: Sandy clay & loam, white clayey sand, gravel, laterite, quartz, granite, limestone. Flats, gentle slopes, breakaways, rock cavities.

Season: July to November

Little laughing leek orchid (Prasophyllum gracile)

Location: Shark Bay to Eyre

Habitat: Sand, peaty sandy clay. Coastal swamps and sandhills, granite outcrops, winter-wet areas.

Season: July to October

Shy sun orchid (Thelymitra graminea)

Location: Perth to Esperance

Habitat: Growing in sandy or lateritic soils in woodlands and forests.

Season: October and November

Eight species ultimately found, however the numbers found were very low. Time to head toward Jerramungup, where we plan to check out a bush fire location, we spotted on the drive over on Monday.

07/10/2022 ….. Lake Toolbrunup & Kebaringup

Anderson Lake NR, Nature Reserves, Numerous days, Road Trip, Western Australian Orchids

Next stop on our winding drive back to Esperance is another new location. Anderson Lake Nature Reserve which is 30kms east as the crow flies from Pootenup Nature Reserve, will hopefully produce some different orchids. As we get close to the location it is apparent that it is much drier so let’s see if we actually find anything at all.

As anticipated, we struggled to find any orchids, however the ones found were indeed different. Very close to where we park, we find our first orchid. The Purple veined spider orchid (Caladenia doutchiae) flowers August through October, between Mullewa and Ravensthorpe. References checked indicate it is found growing on rises around salt lakes, which is exactly the habitat we are currently searching. Four sperate flowers were located, which portray the variable colouring to this species.

Smooth margined, variably coloured, red tipped labellum
Narrow band of labellum calli
Flowers 15 to 30mm across
Purple veins to sepals
Long, shortly clubbed lateral sepals
Short, backswept petals

It was another 15mins or so before we stumbled across another orchid. This time it was the Midget greenhood (Pterostylis mutica) that caught Debs eye. The lime green colouring stands out against the otherwise brown foliage. These small orchids flower July through October, between Wongan Hills and the SA border. They are also found in QLD, NSW, Vic, Tas and SA. Florabase mentions they are known to grow around saline lakes, again confirming we are in suitable habitat.

From the latin MUTICUS (without a point, awn less, blunt) alluding to the blunt petals and sepals.

The next orchid found was a pleasant surprise. First up we thought it was a frog greenhood, but as we settled in to take some photos it became apparent that it was another species. After getting back into the Triton we are excited to note that this is a new species for us. The Ruddy hood (Pterostylis perculta) flowers from late September to early November between Kojonup and Cape Arid National Park. It was only formally named in 2015, previously called sp. “Ongerup’ which alludes to its location. It is a small orchid growing to 150mm in height, may have up to 5 flowers per orchid and is found growing in sandy-clay and clay soils.

Almost hairless labellum
Straight to slightly upcurved lateral sepals
70-150mm in height

As alluded to earlier we had returned to the Triton as this location did not prove overly productive, however finding a new species is always amazing. We head north up to Gnowangerup, then west stopping along the roadside in Kebaringup. I believe this is only our 2nd time visiting this location so we will see what turns up this time.

Straight up the large white spider orchids catch our eye. The Stark white spider orchid (Caladenia longicauda subsp. eminens) is probably the species found, based solely on location. They flower August to early October between Moora and Esperance and can grow to 600mm in height.

Four or more rows of red calli
300 – 600mm in height
Spider on spider orchid

Further orchids are found, though not in great numbers. The Little laughing leek orchid (Prasophyllum gracile) the Cowslip orchid (Caladenia flava subsp. flava) and the Green spider orchid (Caladenia falcata) are all represented by sole specimens.

Cowslip orchid (Caladenia flava subsp. flava)

More Purple veined spider orchids are found in better numbers. Then another single specimen on anorchid is found. The Common mignonette orchid (Microtis media subsp. media) is a widespread orchid being found flowering between Shark Bay and Eyre during the months of September through January. The final orchid found for the day was a good bunch of Jospeh’s spider orchid (Caladenia polychroma), which are found between Boyup Brook and the Fitzgerald River National Park during the months of September and October.

We decide to move on and look for somewhere to stay the night. As we have 2 vehicles and a camper trailer, we make the decision to check into the Ongerup Gardens Caravan Park for the night. It was a choose you own site sort of place, so we parked up close to the ablutions. This was a great day orchid hunting in our wonderful Western Australian outdoors.

07/10/2022 ….. Pootenup Nature Reserve

Nature Reserves, Numerous days, Pootenup NR, Road Trip, Western Australian Orchids

Meeting up with Debbie in Cranbrook this morning. I drove down from Katanning, and she drove up from King River. So, the plan is to take a winding route back to Esperance over the next the next 3 days, with regular stops to search for orchids. After grabbing a cuppa from the Cranbrook store, we head up the Great Southern Highway, but only get as far as Pootenup Nature Reserve, where we pull over for our first exploration. This is a new location, so we are hopeful of finding some orchids.

First up some large Green spider orchids (Caladenia falcata), also called the Fringed mantis orchid, are found with many twins flowering. They can have up to 3 flowers per orchid, so twins are nice to find. They are a common orchid, flowering between Wongan Hills and Jerramungup, from late August to October.

We thought we found a lot of Green spider orchids, but the number of White spider orchids was unbelievable. From the location I feel the large white spider orchids to be the Stark white spider orchid (Caladenia longicauda subsp. eminens), which flowers between Moora and Esperance, during August to early October.

However, some of the white spider orchids are smaller with thinner labellum and shorter fringe segments. After checking the references these ones may be the Tangled white spider orchid (Caladenia longicauda subsp. redacta) which occurs between Collie, Mount Barker and York, growing in sandy-clay soils and seasonally moist flats in forests and woodlands. I will post some pics for you to decide if I am correct in the identification. If not, please let me know.

Other orchids are also found interspersed between all the large green and white spider orchids. A lone Jug orchid (Pterostylis recurva) with 5 flowers in various stages of bloom is one of these. From the reference books having five flowers is somewhat rare, so this is an exciting find, for such a common orchid. Another common orchid found, though not too common at this location, is the Common bee orchid (Diuris decrementum), which is often found growing in clumps and occurs from north of Perth to east of Esperance.

Another common yellow coloured orchid is found but again not common in this location. The Cowslip orchid (Caladenia flava subsp. flava) differs wildly in its markings, as shown by the two specimens found. One has red lines and dots whilst the other is mostly dots. Where the various subspecies overlap these variations cause confusion in making a positive ID.

A hybrid orchid is found which should not have come as a surprise as the probable parents are both found in large numbers. That said, finding a hybrid is always exciting. The named hybrid, Wheatbelt spider orchid (Caladenia x cala) is a cross between the Green spider orchid (C. falcata) and a white spider orchid (C. longicauda).

Another surprise is finding the Pink enamel orchid (Elythranthera emarginata) which is found between Jurien Bay and Ravensthorpe, from October to December. This is a beautiful, bright orchid that grows in sandy, sandy-clay and clay soils in forests, woodlands and shrublands.

Hiding behind the spectacular foursome of Pink enamel orchids you can see some small white orchids. These little beauties are the White fairy orchid (Caladenia marginata), which are found between Jurien and Israelite Bays over the spring months.

Now for the difficult part, trying to ID the smaller spider orchids. The location leads me to believe that the majority of them are the Joseph’s spider orchid (Caladenia polychroma), which is a variably coloured orchid found growing between Boyup Brook and Fitzgerald River National Park during the months of September and October. Listed as growing in woodlands with grassy to herb-rich ground cover, on seasonally damp clay-loam soils.

However, some of the red spider orchids could be the Crimson spider orchid (Caladenia footeana) which is listed as growing between Cranbrook and Binnu, from July through to October.

I struggle with identifying some orchids so I will post the pictures with the expectation that someone will advise me what species they believe them to be. Thank you in advance.

Well, this was an amazing first location for the day. Possibly 10 species and 1 hybrid. Let’s see what the rest of the day produces.

25/09/2022 ….. Gibbo re-visited.

List of Orchids Found, Sunday Drive, Western Australian Orchids

Earlier this season (June) we checked out the burnt area north of Gibson and found greenhoods but nothing else. Now that we are at the other end of the season, we pop out there again to record what is now flowering. After nearly 3hrs searching the area, we were pleased to find so many orchids flowering.
