Not infrequent in British Guiana, Venezuela, Ama- 
zonian Peru and elsewhere in Colombia, Leandra divari- 
cata has been collected hitherto on the Amazonian water- 
shed of Colombia but twice: at Puerto Porvenir, on the 
upper reaches of the Rio Putumayo (Cuatrecasas 10666), 
and at Mocoa (Cuatrecasas 11316). Hermann 11308, 
from the southeasternmost point of the Colombian Am- 
azonia, would seem to indicate a wide distribution for 
this species in eastern Colombia.

LOGANIACEAE 
Strychnos amazonica Krukoff in Brittonia 4 
(1942) 284. 
This collection, determined with some reservation as 
representing Strychnos amazonica, is the first of the spe- 
cies from Colombia. Krukoff and Monachino (in Caldasia 
4 (1946) 45) enumerated Strychnos amazonica as a species 
to be expected in the Colombian Amazonia. It is one of 
the plants the root of which is used by the Kofin Indians 
in preparing arrow-poison.

Fl. Br. Guiana (1848) 1082, nomen: ex Progel in Mar- 
tius Fl. Bras. 6, pt. 1 (1868) 274. 
First reported from Colombia on the basis of a collec- 
tion from the Rio Sucumbios (in Bot. Mus. Leafl. Har- 
vard Univ. 13 (1949) 290), Strychnos Erichsonii is appar- 
ently one of the most abundant species of this genus in 
the upper Putumayo basin where it is sought by the 
Kofan Indians for use in preparing cuvrare.
