OBSERVATIONES 
BY 
RicHarp Evans SCHULTES 
A NUMBER of recently made collections, chiefly from 
Amazonian Colombia, represent hitherto undescribed 
concepts or range extensions or are the basis of interest- 
ing ethnobotanical observations. It appears advisable to 
present the following miscellany of notes on the signifi- 
cance of these collections as a contribution to our under- 
standing of the South American flora, especially that of 
the northwesternmost reaches of the Amazonian system. 
It is with pleasure that I thank Dr. B. A. Krukoffand 
Mr. Joseph Monachino of the New York Botanical Gar- 
den for determining the collections of Menispermaceae 
and Strychnos; Mr. Charles Schweinfurth of the Botan- 
ical Museum of Harvard University for identifying the 
orchids; and Dr. Adolpho Ducke of the Instituto A gro- 
nomico do Norte (Belém do Para) for naming the col- 
lection of Leptothyrsa Sprucei.
