Distribution. Small tree to 20 m, conspicuous for its subtriplinerved, yellow- 

 green leaves, sericeous on the lower surface, occurring principally in sandstone 

 areas of Brazil, Venezuela, British Guiana, and Suriname, and adjacent areas 

 usually in woods along streams at an altitude from 100-200 m. VENEZUELA.

This taxon has been treated heretofore as conspecific with E. sericea Nees, 

 the much-collected species from the Antilles, and superficially resembles it. Close 

 examination of Meissner\s variety y bracteolata discloses significant and con- 

 sistent differences; namely, the less rigidly coriaceous leaves, distinctly sub- 

 triplinerved, with a lack of prominent nerves branching from the costa in the 

 upper portion, or these, if present usually but not always, obscure. In general, the 

 flowers are less coarse and the pedicels more slender.
