ContTINUED studies of recent collections from northwest- 
ern South America, chiefly from Colombia, have dis- 
closed a number of plants which are, for one reason or 
another, of importance to our growing understanding of 
the flora of this critical part of the New World tropics. 
Most of the plants herein discussed are from Amazonian 
Colombia. 
I acknowledge with thanks the collaboration of Dr. 
Lyman B. Smith, of the Smithsonian Institution, who 
is responsible for the work on the Bromeliaceae, and of 
Dr. Alicia Lourteig, Guggenheim Fellow in Botany at 
the Gray Herbarium of Harvard University, who has 
contributed the section on Cuphea.

Further studies on the aroids of Amazonian Colombia
