Two new species of the Andean genus Aa (Orchidaceae, Spiranthoideae) are described: Aa lozanoi Szlach. and S. Nowak, and Aa figueroi Szlach. and S. Nowak. They are restricted in distribution mainly to Cordillera Oriental in the department of Cundinamarca, however, A. lozanoi was also collected in Cordillera Central and A. figueroi in Sierra Nevada...

Lepanthes agatarum, a new species of Orchidaceae from the eastern Andes of Colombia, with cup-shaped flowers, is described and illustrated. The new species is similar to Lepanthes calocodon from Venezuela, but can be distinguished from it by its longer petals and a bilaminate lip with the blade apices elongate, long acuminate-slender to filiform. R...
A new species of Browningia (Cactaceae, Cactoideae, Browningieae) from the high valley of Chicamocha river (Boyacá, Colombia), which confirms the disjunct distribution of this genus, -to date considered endemic from the Center-Andean region-, is described and illustrated. The habitat, distribution and its condition as a promising species for Colomb...
A synopsis of the genus Orchidotypus Kraenzl. in Colombia is presented. Morphological descriptions of all national representatives of the genus are provided, together with information about their habitat, ecology and general distribution, detailed illustrations of the studied plants, and an identification key for Colombian Orchidotypus species. A n...
In Colombia, four species of Triphora (Orchidaceae) are recognized. Two species (Triphora galeanoi and T. vichadaensis) are newly described. As circumscribed here, the two new species occur exclusively in Colombia apart from T. foldatsii, being known from Colombia and Venezuela, and T. gentianoides, ranging from the USA (Florida) in the north to Co...
Resumen
Three new small-flowered Cyrtochilum species from Colombia and Peru are here described, illustrated and compared with similar species, and with one new taxonomic combination. The first species differs from all other Cyrtochilum species by the curved horn-like structures on the lip callus. The second species differs from its most similar re...

... f. (Orchidaceae: Cranichidinae) includes about 25 Neotropical species distributed in the Andean region, although, Aa paleacea (Kunth) Rchb. f. reaches to the mountains of Costa Rica (Trujillo and Vargas 2011;Szlachetko and Nowak 2014). In South America, this genus is a component of different kinds of vegetation, likes open scrubs, woodlands, damps mountain meadows and paramo of the northern Andes above 2600 m.a.s.l. ...

... (Coccuci 1954;Schinini et al. 2008;Martín and Scrocchi 2016). This genus is characterized by its elongated peduncle, with tubular and hyaline-diaphanous sheaths, generally greenish-white (rare black or orange) and non-resupinate flowers, dorsal sepals and petals free from column, cucullate lips with involute margin, disc with a pair of subglobose basal calli (Trujillo and Vargas 2011;Szlachetko and Nowak 2014). However, this genus have a low morphological variation and an unstable systematic status since they have been transferred to Altensteinia Kunth or Myrosmodes Rchb. ...
A new species, Aa tenebrosa, from the Yungas Montane Grasslands is described,
illustrated, and compared to similar species. Descriptions, brief taxonomic notes, and data on the
ecology of Aa species from the southern central Andes (Argentina) are provided.
Myrosmodes noemiae (Orchidaceae), a new species from the Puna biome in the high northwestern Argentine Andes, is described and illustrated. This species is currently known from a single population; its habitat, a distribution map, and a key to distinguish it from other species of Myrosmodes growing in the Andean region are presented. In addition, we present an updated distribution of M. gymnandra, clarify the holotype of M. nubigena, and designate a lectotype for Altensteinia paludosa, the basionym of Myrosmodes paludosa.
Eight new species of the genus Gomphichis from Colombia are described. Each species is illustrated, and detailed habitat and distribution data are provided. A distribution map of the new species is presented. A dichotomous key for determination of the Gomphichis species in northern South America is provided. Conservation status assessments are provided for each species; current International Union for Conservation of Nature (IUCN) Red List categories and criteria are listed. A brief discussion of spiranthoid orchids taxonomy, conservation status of species, endemism in the Andes and paramo are presented.
