BRACHYPEZA

Brachypeza Garay (1972: 163) . Type species: Brachypeza archytas (Ridl.) Garay (basionym: Saccolabium archytas Ridl. ).

Pteroceras as previously circumscribed ( Pedersen 1993) is clearly polyphyletic, with some species forming a strongly supported clade that includes Brachypeza , whereas the type of Pteroceras , P. teres (Blume) Holttum , falls in a clade with Tuberolabium and several other genera. The main morphological character distinguishing Pteroceras s.s. from Brachypeza is found in the rachis of the inflorescence: in Pteroceras flowers arise from sharply delimited, longitudinal cavities on the rachis, whereas there are no such depressions on the rachis of Brachypeza ( Fig. 1A ).
