Cynometra Zamorana is apparently not closely allied 
to any known species of this interesting genus. It is dis- 
tinctive at once because of the large size of its leaves and 
its legumes. The Indians of the upper Vaupés River eat 
the dry, powdery, sweet, pulpy aril of the seed and use 
the trunks of the large tree in the construction of rafts. 
Among the Spanish-speaking inhabitants of the same 
region, Cynometra Zamorana is called coca, the same 
term which is widely used to refer to the completely 
unrelated narcotic plant M/rythroaylon Coca Lam. 
I have named this beautiful, majestic tree in memory 
of one of the boys who penetrated the upper Apaporis 
River with me on my first expedition to that uninhabited 
area. Armando Zamora, 19, a native of the town of San 
Martin, Intendencia del Meta, lost his life by drowning 
when he was swept through the lowermost rapids in the 
Macaya River on April 7, 1943, while performing his 
duties on that expedition.
