not been reported hitherto from eastern Colombia. In 
the trapecio amazonico of Colombia, it is known by the 
Brazilian name flor da terra, and a strong decoction of 
the entire plant is highly esteemed in the treatment of 
dysenteric disturbances and diarrhea.

I have noticed individuals of this gigantic tree on some 
of the sandy islands of the Amazon River in the Colom- 
bian trapecio amazonico, but no fertile specimens were 
available. The collection cited below, from the Brazilian 
island of Aramaca near Tabatinga, only a few kilometers 
from the Colombo-Brazilian boundary, is a close match 
for the type which came from a not-too-distant locality 
on the Rio Ucayali in Loreto, Peru. This species has 
apparently not been reported hitherto from Colombia or 
Brazil. 
Brazit: Amazonas, Ilha Aramaca, near Tabatinga. Enormous tree,
