Attalea pycnocarpa versus Attalea sagotii (Arecaceae): the resurrection of a misunderstood Amazonian palm

Fieldwork in two localities of the Colombian Amazon reveals that the palm Attalea pycnocarpa, originally described from the Orinoco River in Venezuela, is a distinct species, and not a synonym of the acaulescent A. sagotii, as tentatively treated in the recent monograph of the genus. The species is redescribed, illustrated, and compared with A. sagotii.
