This is the first record of the genus Platycarpum from 
Colombia. The new species is related to Platycarpum 
orinocense HBKK. and to P. Duche: Steyermark, but, 
unlike these species, it has mostly ternate instead of op- 
posite leaves. The flowers are considerably smaller than 
in either of those species, and the pubescence is of a much 
shorter type than that found in either Platycarpum orin- 
ocense or P. Ducher. The scabridulous upper leaf-surface 
of Platycarpum Schultesii resembles most closely the type 
of pubescence found in P. Duchkei, but the former species 
differs from the latter, among other particulars, in the 
short pubescence of the lower leaf-surface and of the pet- 
ioles and rachis. The only other species of Platycarpum 
with ternate leaves is P. rhododactylum Woodson & 
Steyermark of Venezuela.
