The taxonomic equations Melanoxylon speciosum Benoist = Recordoxylon a
mazonicum (Ducke) Ducke and Elephantomene eburnea Barneby & Krukoff (1
974) = Cionomene javariensis Krukoff(1979) are proposed. The new combi
nation Recordoxylon speciosum (Benoist) Gazel is validated, and the wi
dely discontinuous distribution of the monotypic genus Elephantomene i
s mapped.
