A NOMENCLATORIAL NOTE 
BY 
OaKES AMES 
Epidendrum neoporpax 4 mes, nom. nov. 
Epidendrum porpax Reichenbach filius in Flora 48 
(1865)278, not Reichenbach filius in Bonplandia 3 
(1855) 220. 
Epidendrum vestitum Ames in Sched. Orch. 4(1923) 
51, not HMpidendrum vestitum Swartz, Prodr. (1788) 
124 which is Ornithidium vestitum(Sw.) Reichenbach 
filius in Walp. Ann. Bot. 6(1868) 491. 
Through an oversight, H.G. Reichenbach described 
two species, one a native of Nicaragua the other a native 
of Cuba,under the name Mpidendrum Porpax. The Cuban 
species was described about ten years later than the Nica- 
raguan one and has to be given a new name. In Sched- 
ulae Orchidianae 4(1923)51, I proposed the new name 
Epidendrum vestitum, but as a result of recent changes 
in nomenclatorial rules this name is invalidated because 
of the Mpidendrum vestitum of Swartz published in 1788, 
a species which is now referred to the genus Ornithidium. 
Mpidendrum neoporpax is an extraordinarily rare 
species which is only known from Cuba,
