Description:
Author: Scott A. Mori
Type: PANAMA. Panama: El Llano-Cartí Rd., 11-12 km from Inter-American Hwy., 300-400 m, 28 Jun 1975 (fl, fr), Mori et al. 6887 (HOLOTYPE: NY; ISOTYPES: A, BM, COL, F, G, INPA, K, MO, P, MA, RB, U, US, VEN).
Description: Understory trees, to 20 m tall (based on few trees). Bark dark brown, scalloped. Leaves: petioles 5-10 mm long; blades 8-11 x 3-5 cm, elliptic, coriaceous, black punctate abaxially, the base acute, the margins entire, the apex acuminate; secondary veins in 8-10 pairs, the higher order venation inconspicuous, especially adaxially. Inflorescences terminal (suprafoliar) or axillary in uppermost leaves, unbranched racemes, these sometimes clustered, the rachis 1-4 cm long, puberulous; pedicel/hypanthium 20-30 mm long, tapered to articulation, not sulcate, glabrous, sparsely lenticellate. Flowers ca. 3 cm diam.; calyx with six lobes, the lobes ovate to widely ovate, 5-5.5 x 3.5-4 mm, with erect orientation at anthesis, convex abaxially, the bases slightly or not imbricate; petals 6, white; androecial hood coiled, yellow. Fruits 2-4 cm diam., cup-shaped, usually slightly asymmetrical with pedicel obiquely oriented, the calycine ring conspicuous with calyx-lobes thickened and woody, inserted well above middle, the supracalycine zone erect, the infracalycine zone rounded to pedicel, the pericarp 2-5 mm thick, woody, more or less smooth, the operculum convex. Seeds 1-2 per fruit, rounded in cross-section; aril lateral, not conspicuous (at least in stage observed).
Common names: None recoreded
Distribution: Known only from the type locality
Ecology: In non-flooded moist forests below 500 m.
Phenology: Flowering collections have been made in Jun and fruits with seeds have also been collected in Jun. An immature fruit collection comes from Mar and a fruiting collection with old seed in Feb.
Pollination: The androecial hood is coiled, yellow and presumably produces nectar which suggests that bees are the pollinators
Dispersal: The species has a lateral aril which may attract animals
Predation: No observations recorded.
Field characters: This species is characterized by its relatively small flowers with long pedicels and small, cup-shaped fruits with long, persistent pedicels. The relatively small, coriaceous leaves also help in the recognition of the species.
Taxonomic notes: Based on the field characters, there are no other species like E. longipedicellata in Mesoamerica.
Conservation: IUCN Red List: Not on list.
Uses: None recorded
Etymology: The species epithet refers to the long pedicel that persists on the fruit after it falls.
