Strychnos brachiata Ruiz & Pavon FI. Peru. et 
Chil. 2 (1799) 80. 
This species, known apparently only from subandean 
Peru and Bolivia (Krukoff and Monachino in Brittonia 
4 (1942) 269), is now registered from Colombia (Krukoff 
and Monachino in Bol. Téen. Inst. Agron. Norte 12 
(1947) 10) on the basis of the following collection. 
CotomsB1A: Comisaria del Putumayo, Rio San Miguel 6 Sucumbios, 
Santa Rosa y los alrededores. Nombre kofan: se-hé-pa. ‘“Vine. Root 
used in preparation of arrow poison.’’ 7—8 abril, 1942, Richard Evans

Strychnos Erichsonii Richard Schomburgh Faun. 
FI. Br. Guiana (1848) 1082, nomen; ex Progel in Mar- 
tius Fl. Bras., 6, pt. 1 (1868) 274. 
An Amazonian species, Strychnos Hrichsoni was col- 
lected in Brazil (Ducke in Bol. Técn. Inst. Agron. Norte 
83 (1945) 14) near the Colombian frontier, and was re- 
ported by Krukoff and Monachino (in Caldasia 4 (1946) 
46) as one of the species to be expected in the Amazon- 
ian regions of Colombia. The collection cited below es- 
tablishes the occurrence of the species in the southwest- 
ernmost sector of the Colombian Amazon area. It is 
known also from British and Dutch Guiana and Vene- 
zuela.

Conejo y los alrededores, en frente de la Quebrada Conejo. Nombre 
kofan: ir-rro-chee, 2-5 abril, 1942, Richard Evans Schultes 3524. 
Strychnos Jobertiana Bail/lon in Adansonia 12
