COMPOSITAE 
Gongylolepis maroana Badillo in Bot. Soc. Venez. 
Cienc. Nat. 8 (1948) 287. 
The collections cited below are extremely significant 
because they place the genus Gongylolepis for the first 
time far within Colombian territory and very greatly 
extend to the southwest the known range of this species. 
Gongylolepis maroana was described from material 
collected by Llewelyn Williams at the town of Maroa 
on the Venezuelan side of the lower course of the Rio 
Guainia. Therefore, coming from so near Colombian 
territory, this species was to be expected in Colombia, 
but Mount Chiribiquete is fully 500 kilometers to the 
southwest. Allen 3167 and Schultes 5740A are very good 
matches for the type, the only other collection of this 
species. 
Gongylolepis is a small genus associated with the an- 
cient flora of the Guianan-Venezuelan land mass. The 
first species described was Gongylolepis Benthamiana 
Rob. Schomb. from the Mazurini River drainage-area 
in British Guiana. Recently, Blake described Gongylo- 
lepis glaberrima and G. erioclada from Mt. Duida. The 
fourth species, Gongylolepis maroana, is the westernmost 
representative of the genus. The two collections cited 
below emphasize the strong relationship between the 
mountains of the upper Apaporis and the Vaupés and 
the Duida-Roraima mass.
