RicuHarp Evans ScHULTES'’ 
REcENT work on a number of South American plant 
collections, for the most part of Amazonian origin, has 
uncovered several novelties and has provided us with 
additional information of a phytogeographical or ethno- 
botanical nature. The following notes are offered as a 
contribution to our knowledge of this interesting part 
of the New World. 
I am grateful to a number of my botanical colleagues 
for their determination of plants in certain groups: Dr. 
L. H. Bailey and Dr. H. Emery Moore (Palmae); Dr. 
Robert Woodson (Apocynaceae); Dr. José Cuatrecasas 
(Chloranthaceae, Moraceae, and Musaceae); Dr. Harold 
N. Moldenke (Menispermaceae); and Dr. Bassett Ma- 
guire (Rapateaceae). It is also a pleasure to express my 
appreciation to Mr. Elmer W. Smith for his beautiful 
and highly accurate drawings of several of the newly de- 
scribed species. The drawings of the concepts of Her- 
rania were made possible by a grant from the American 
'Botanist, Bureau of Plant Industry, Soils, and Agricultural Engi- 
neering, Agricultural Research Administration, United States Depart- 
ment of Agriculture; Research Fellow, Botanical Museum, Harvard 
University.
