Description
9c. Eperua grandiflora subsp. ciliata E.A. Fortes & Mansano, subsp. nov.
(Figures 9, 35, 36, 37)
Type:— GUYANA. Potaro-Siparuni, Potaro River below Waratuk Falls, 107 m elev., 5°16’57”N 59°21’39”W, 05 September 2006, Redden K. M. et al. 4029 (holotype US [00963900]!).
Diagnosis: — Eperua grandiflora subsp. ciliata shares with other subspecies of E. grandiflora the free stipules, 2–3- jugate leaves, and persistent bracteoles attached to the higher portion of the pedicels or at the base of the hypanthium. It also shares irregularly villous sheath, and glabrous ovary and fruits with subsp. grandiflora. Eperua grandiflora subsp. ciliata differs from other subspecies by the glabrous inflorescences, pedicel, hypanthium, and sepals (vs. with indumentum in subsp. grandiflora and subsp. guyanensis), bracts and bracteoles glabrous with ciliate margin (vs. with indumentum in subsp. grandiflora and subsp. guyanensis), and larger [4.7–5.6 × 3.8–5.9 mm] bracteoles (vs. smaller [1.3–3.9 × 1.5–3.7 mm] in subsp. grandiflora and subsp. guyanensis).
Leaves, margin flat. Inflorescences glabrous; bracts glabrous, ciliate; bracteoles 4.7–5.6 × 3.8–5.9 mm, glabrous, ciliate; pedicel glabrous; buds, glabrous. Flowers: hypanthium, sepal glabrous; stamens, sheath irregularly villous; ovary glabrous. Legumes glabrous.
Phenology:— Flowering in September.
Distribution:— Potaro River in the Esequibo River basin (Guyana, Potaro-Siparuni). It is sympatric with E. jenmanii, which also occurs in the same basin.
Habitat:— It occurs in floodplain (riparian) forests, and wallaba forests, on white sand soils from 107 to 498 m elev.
Occurrence in protected areas:— Kaieteur National Park (Guyana).
Etymology:— The specific epithet relates to its ciliate bracts and bracteoles.
Vernacular names:— unknown
Uses:— unknown.
Taxonomic notes:— Eperua grandiflora subsp. ciliata is known by only three specimens which shows some sympatry with E. grandiflora subsp. guyanensis . In the upcoming phylogeny of the genus E. grandiflora subsp. ciliata was sampled with one accession that appears as a sister group to the other two subspecies of E. grandiflora (Fortes et al. in prep.). This lineage grouping the three subspecies of E. grandiflora received maximum phylogenetic support.
Specimens examined (paratype):— GUYANA. Cuyuni-Mazaruni, Pakaraima Mts., Mazaruni River, trail approx. 0.8 miles North from mining camp, 570 m ele., 6°5’4”N 60°39’2”W, 21 February 2004, Redden K . M. et al. 2059 (NY[03777031] image!, US [01952126]!). Potaro-Siparuni, Tukeit Landing below Kaieteur Falls on Potaro River, 498 m elev., 5°12’16”N 59°27’11”W, 02 September 2006, Redden K . M. et al. 3962 (CAY[109805] image!, US[00963896]!).
