Description:
Author: Scott A. Mori & Nathan P. Smith
Type: Colombia. Chocó: Jequedo, 41 km W of Las Animas on Pan American Hwy. (under construction), ca. 10 km E of Río Pato, alt. 220 m, 12 Jan 1979 (fl), Gentry & Renteria 24106 (holotype, NY; isotypes, HUA, MO, NY).
Description: Large trees, to 45 m tall. Leaves: petioles 15-25 mm long; blades oblong to narrowly oblong, 35-61 x 15-20 cm, glabrous, punctate abaxially, the base obtuse, the margins entire, the apex acuminate; secondary veins in 26-32 pairs. Inflorescences usually from branches below leaves in leaf scar axils, racemose, the rachis 1-5 cm long, the pedicels glabrous, ca. 5 mm long, green with whitish punctations when fresh, black with whitish punctations when dry. Flowers: hypanthium cuneate, green with whitish punctations; calyx nearly entire, forming rim 2 mm wide, green with whitish punctations; petals 6, pink flushed with yellow; androecium zygomorphic, the staminal ring with ca. 400 stamens, the filaments clavate, 1.8-2.5 mm long, the anthers 0.5-0.7 mm long, the ligule yellow flushed with pink, the hood 17-23 x 15-17 mm, forming 3 or 4 coils, yellow, the appendages flushed with pink; gynoecium with 2-locular ovary, the style erect, ca. 3 mm long. Fruits and seeds poorly known.
Common names: None known.
Distribution: Known from central Chocó to Valle, Colombia. Gentry (pers. comm.) reported that E. integricalyx was the second most common among seven species of Lecythidaceae found by him in a 1000 square meter sample near Tutunendo, Chocó.
Ecology: A large canopy or emergent tree.
Phenology: Flowers have been collected from Jan to JuI, and Oct. Fruits have been collected in Mar.
Pollination: No reports of pollination have been recorded.
Dispersal: No reports of pollination have been recorded.
Predation: No observations recorded.
Field characters: This is the only species of Eschweilera with an entire calyx. The large leaves, racemose inflorescences from the stems below the leaves, and the pink to red petals and yellow androecial hood are other diagnostic features of this species.
Taxonomic notes: The large, similar leaves of E. integricalyx and E. sclerophylla can be separated by the percurrent tertiary veins of the former in contrast to the reticulate ones of the latter species.
Conservation: IUCN Red List: Vulnerable B1+2c ver 2.3 (World Conservation Monitoring Centre 1998. Eschweilera integricalyx. In: IUCN 2013. IUCN Red List of Threatened Species. Version 2013.2. www.iucnredlist.org. Downloaded on 26 February 2014.).
Uses: None known.
Etymology: The name "integricalyx" refers to nearly entire calyx.
