 amarillas." Cano Guazuriapana, Rio Atabapo near San Fernando de Atabapo,

8. levelii is perhaps most closely allied to 8. purpureum from which it differs 

 by having many fewer pairs of pinnae and leaflets (these ^omewhat different in 

 shape and almost glabrous) and shorter inflorescences of pubescent flowers. 



The new species is named in honor of the collector, who has for many years 

 been a very important member of the expeditions from the New York Botanical 

 Garden to Venezuela. He is usually in charge of navigation on the rivers, but, 

 in addition, he has acted as cook, he has cut trail, and, most important, he has 

 become an excellent botanical collector and a staunch friend.

"Arbol 10 m. Flores blaneas. " Cano Cupaven, Rio Orinoco at mouth of Rio Atabapo,

This is the first report of this Brazilian species in Venezuela; it was previ- 

 ously known from the State of Para and it has recently been collected in Ama- 

 zonian Colombia {Schultes & Cabrera 15003).
