Notes on Dacryodes Vahl, including a new species from the Rio Negro basin in Amazonia. Studies in neotropical Burseraceae. XI. Brittonia 54: 266–274. 2002.—Dacryodes is a poorly known pantropical genus of some 67 species; a new revision now under way reveals that the Neotropical region is home to at least 36 species, 14 of them undescribed. The genus is introduced with a brief taxonomic history, a presentation of the putative differences from Pseudodacryodes, a discussion of the infrageneric classification, and a preliminary comparison of Neo- and Paleotropical taxa. Characteristics that make the genus difficult to study are pointed out. Dacryodes negrensis, the first in a series of new taxa, is described and illustrated.
