Description:
Author: Scott A. Mori & Nathan P. Smith
Type: Venezuela. Aragua: Rancho Grande, Parque Nacional Aragua, Subida de los Vueltas, 28 Aug 1947 (fl), Pittier 15558 (holotype, VEN; isotype, VEN).
Description: Trees, medium-sized. Leaves: petioles 22-27 mm long; blades oblong, 18-24 x 9-10 cm, coriaceous, smooth, somewhat glaucous adaxially, glabrous, punctate abaxially, the base rounded, the margins entire, the apex short acuminate; secondary veins in 16-17 pairs. Inflorescences terminal or axillary, once-branched, the principal rachis racemose, buff pubescent, 2-12 cm long; pedicels buff pubescent, ca. 15 mm long. Flowers ca. 2.5-3.0 cm diam.; hypanthium cuneate, buff pubescent; calyx-lobes 6, widely ovate, 12-13 x 8-11 mm, erect, imbricate, carinate abaxially, gibbous at base, plane adaxially; petals white; androecium zygomorphic, the staminal ring with ca. 200 stamens, the filaments clavate, ca. 2.5 mm long, the hood forming 3 coils, yellow; gynoecium with 2-locular ovary, the ovules 57 per locule, attached to floor of locule, the style obconical, 3.5 mm long. Fruits turbinate, 8 x 6 cm, the supracalycine zone above middle, 1 cm wide, the calyx-lobes persisting as woody knobs, the operculum convex, very slightly umbonate, the pericarp 8 mm thick. Seeds with lateral ariI.
Common names: None known.
Distribution: Known only from Parque Nacional Henri Pittier, Venezuela.
Ecology: A medium-sized tree of cloud forests at 1200-1400 m.
Phenology: Flowers have been collected in Aug and mature fruits in Mar.
Pollination: No observations recorded but most likely pollinated by bees.
Dispersal: No observations recorded but the lateral aril may be eaten by animals.
Predation: No observations recorded.
Field characters: See taxonomic notes.
Taxonomic notes: The three collections of this species probably came from a single tree and therefore we know little about intraspecific variation. Nevertheless, the larger leaves with more lateral veins and longer petioles; the pubescent axes of the inflorescence, pedicels, and hypanthia; the white petals; and the turbinate fruits separate it from the sympatric E. tenax.
Conservation: IUCN Red List: Vulnerable D2 ver 2.3 (World Conservation Monitoring Centre 1998. Eschweilera beebei. In: IUCN 2013. IUCN Red List of Threatened Species. Version 2013.2. www.iucnredlist.org. Downloaded on 25 February 2014.).
Uses: None known.
Etymology: This species was named in honor of William Beebe.
Source: Based on Mori and Prance in Mori and Prance (1990).
