Discussion:This species is related to P. pliceita Spruce ex Benth., from which it differs in the less coriaceous leaf-blades with longer pubescence, shorter and more slender peduncles, and longer, narrower, and more pointed calyx-lobes. From P. hirsuta Spruce ex Benth. it differs in the shorter peduncles and less pubescence on all parts, and from P. guianensis Aubl. it may be distinguished by the short peduncle, and pubescent leaves and stipules.
