As more and more collections of plants from northwestern 
South America are studied, our knowledge of the dis- 
tribution of many of the poorly understood genera and 
species increases apace. Occasionally, undescribed con- 
cepts are found. In addition, ethnobotanical information 
of considerable interest often is made available through 
the field studies connected with the collections under 
study. This paper is a continuation of a series devoted 
to the publication of such miscellaneous data. 
It is a pleasure to acknowledge the collaboration of 
Dr. Lyman B. Smith of the Smithsonian Institution, 
who is responsible for the work on the Bromeliaceae; of 
Mr. Noel Y. Sandwith of the Royal Botanic Gardens, 
Kew, who has described a new concept in the Bignon- 
zaceae; of Dr. Harold N. Moldenke of the Trailside Mu- 
seum, New Jersey, who has identified the H7riocaulaceae; 
of Dr. Alicia Lourteig of the Musée d’ Histoire Natu- 
relle, Paris, who determined Cuphea; and of Dr. Julian A. 
Steyermark of the Chicago Museum of Natural History 
and Dr. José Cuatrecasas of the National Science Foun- 
dation, who have contributed studies in several genera. 
The families are arranged in conformity with the sys- 
tem proposed by Engler and Gilg.
