these two collections were, in the early period of inves- 
tigation of the genus, referred to Cunuria Spruceana, 
there is no Justification for Pax’s citation of Clusiophyl- 
lum Sprucet as a synonym of C. Spruceana (Engler 
Pflanzenr. 1V. 147 (Heft 42) (1910) 16). 
Little is known about the latex of Cunuria crassipes. 
In Allen 3068, it was ‘‘yellowish, scant, coagulating to 
a non-elastic gum’’; while in Baldwin 3673 and 3675, 
the color of the latex is reported to be white. 
In the opinion of the writers no known species of Cu- 
nuria appears to be promising as a commercial latex 
plant.
