Description
Author: Scott A. Mori and Ghillean T. Prance
Type: Type. French Guiana. Saül, Monts La Fumée, 3°37'N, 53°12'W, 19 Aug 1982 (fl), Mori &Boom 14746 (holotype, NY; isotypes, CAY, INPA, K, M, MG, MO, P, U, WIS).
Description: Petals red or maroon, not in rolled at their margins.
Common names: None recorded.
Distribution: Endemic to French Guiana and Amapá, Brazil.
Ecology: A common, but scattered canopy tree of non-flooded forests often found on ridge tops.
Phenology: This subspeces flowers most abundantly from Jul through Sep.
Pollination: In a study of pollination of this subspecies in central French Guiana by Mori & Boeke (1987), the only insect observed to enter the flowers in three hours of observation was the relatively robust Trigona capitata. This bee made frequent visits to the flowers which it entered with its ventral surface toward the androecial hood. It remained within the flowers for up to 15 seconds while it collected yellow (fodder) pollen from the hood anthers. Upon leaving yellow pollen was clearly visible in its corbiculae while white (fertile) pollen from the staminal ring was deposited on the back of its head and dorsal thorax.
Dispersal: No observations recorded but bats probably eat the arils and disperse the seeds.
Field characters: A canopy tree with a cylindric trunk; deeply furrowed bark with a red inner bark; red petals with flat margins; cylindric fruits; and seeds with a basal aril.
Taxonomic notes: See notes under in species page.
Uses: None recorded.
Etymology: The name of the subspecies refers to the red petals.
