Zygostates Bradei (Schlir.) Garay comb. nov. 
Basionym: Dipteranthus Bradei Schltr. in Anex. Mem. 
Inst. Butan. Soc. Bot. 1, pt. 4: 65, 1922. 
Synonym: Zygostates rotundiglossa Pabst in An. XIV 
Congr. Soc. Bot. Bras. 21, 1968. 
Recently, I saw a specimen of this species in the 
Reichenbach Herbarium with an unpublished name 
under Zygostates. The material was collected by Fritz 
Mueller in Santa Catarina. Zygostates rotundiglossa is 
in no way separable from this species. 
Ornithocephalus stenoglottis Rchb.f. in Flora 
69: 551, 1886. 
Orniihocephalus longilabris Schltr. in Fedde Rep. 
Beih. 9: 114, 1921. 
When Reichenbach described Ornithocephalus steno- 
glottis, he recorded neither the country of origin nor the 
name and number of the collector. The type specimen 
in the Reichenbach Herbarium, however, shows JF. C. 
Lehmann 3370. Both Schlechter and Schweinfurth as- 
sign this species to Peru, but I am sure it is of Colombian 
origin, for Lehmann collected in South America only in 
Colombia and in neighboring parts of Ecuador.
