otherwise indicated, all descriptions are based entirely on specimens 
examined. The following abbreviations are used in referring to

No species of énorea is known to be of much economic impor- 
tance, although a few are used by natives for one purpose or an- 
other. To this fact, as well as to a lack of striking features in habit 
or color, is due their comparative paucity of vernacular names. 
The only American species for which I have been able to find native 
names and uses recorded are listed here. 
Rinorea physiphora, of the Rio de Janeiro region, is known as 
“lobolobo,” and the leaves are said to be boiled and eaten as greens 
by negroes, a use for which they seem singularly unfitted. St. 
Hilaire, however, was of the opinion that the species might be 
improved and made of some importance by cultivation. Baillon 
states that the astringent bark of the same species is used as a 
febrifuge. ‘The native name of R. riana in Colombia is given as 
“jazmin,” and in Venezuela as “rabo de cachicamo” and “taba- 
quito.” The names “ conohorié” and “jacamim-renepea” are given 
for f?. flavescens. Rinorea hummelii is known in British Honduras 
as “ wild coffee.”
