rose-purple color of its petals appears to be unique in 
the genus. 
**Navia Lopezi is named in honor of the late Francisco 
L6pez whose hard and enthusiastic work as a co-collector 
with Schultes in the Amazon has enhanced our knowl- 
edge of the vast, unknown eastern part of Colombia and 
adjacent Brazil.”’ 
Brazit: Estado do Amazonas, Cerro Dimiti, upper Rio Negro basin,

longa. Bracteae florigerae late ovatae, acutae, quam 
sepala bene breviores, integrae, tenues. Flores sessiles.

Concerning this new species Dr. Smith states: ‘‘AI- 
though its leaf margin is slightly irregular, Navia myri- 
antha shows no real teeth, such as all previously de- 
scribed species have. In this character, it is like N. 
Lopezu, but it differs on nearly all other points.”’
