Specimen 1: Isotype -- G. Herrera C.

Description:

Author: Scott A. Mori

Type: COSTA RICA. Puntarenas: Cantón de Osa, Sierpe, San Juan, cuenca superior del Río San Juan, estribaciones Cerros Chocuaco (8° 43' 50" N, 83° 33' 05" W), 580 m. alt., 21 Jul 1990 (fl), Herrera 3997 (HOLOTYPE: NY; ISOTYPES: CR, MO).

Description: Understory to canopy trees, 10-35(45) m tall. Bark whitish (fide Herrera 3997). Leaf petioles 5-7 mm long; drying blackish; blades 10-15 x 3-5 cm, elliptic to narrowly elliptic, blackish punctuations present, chartaceous, the adaxial surface not smooth and shiny, the base acute to obtuse, the margins entire, the apex acuminate to long acuminate; secondary veins in 11-13 pairs, plane adaxially. Inflorescences from twigs below leaves (cauline), axillary, or sometimes appearing terminal (suprafoliar), unbranched or weakly branched, the rachis 2.5-8 cm long, somewhat zig-zagged, slender, glabrous to puberulous, lenticellate; pedicel/hypanthium 5-9 mm long, slightly tapered to articulation, not sulcate, glabrous to puberulous, lenticellate, drying brown. Flowers estimated at 2-2.5 cm diam.; calyx with 6 lobes, the lobes ovate to widely ovate, 1.5-2 x 1.5-2.5 mm, horizontally oriented at anthesis, thick, gibbous at base abaxially, the bases not imbricate; petals white to yellowish white; androecial hood with triple coil (see image below), yellow. Fruits depressed globose to nearly globose (including operculum), 3-4.5 x 4.5-5.5 cm, the calycine ring visible but not expanded, the supracalycine zone erect, the infracalycine zone rounded to pedicel, the pericarp exterior, reddish-brown, lenticellate (especially conspicuous when still green), the operculum convex, not umbonate. Seeds 6-7 per fruit, ca. 3 x 3 cm, triangular in cross section; aril spreading.

Common names: None recorded.

Distribution: Puntarenas in the vicinity of the Osa Peninsula in wet forests. One collection (Hammel et al. 17832) comes from Parque Nacional Braulio Carrillo in the province of Heredia and another collection that appears to belong to this species comes from Honduras.

Ecology: Wet, lowland forest at less that 600 meters on the Osa Peninsual, Costa Rica.

Phenology: Flowering collections come from Mar, May, Jun, Jul and the single fruiting collection comes from January.

Pollination: No information recorded but most likely pollinated by bees.

Dispersal: No information recorded but seed surrounded by a spreading aril that might be eaten by animals.

Taxonomic notes: This species had previously been identified as E. integrifolia which is also common on the Osa Peninsula. The leaves of some collections of this species (e.g., Hammel 18281) are narrower than those of other collections but this is interpreted as intraspecific variation.

Conservation: IUCN Red List: Not on list (March 2014).

Uses: None recorded.

Etymology: This species is name for Reinaldo Aguilar, collector and expert on the flora of Costa Rica. Reinaldo has helped me to understand the species of Lecythidaceae in Costa Rica.
