Sepala petalaque aequalia, sub anthesi patentia, sepala lateralia pedi gynostemii 

 affixa, mentum proprium nullum formantia. Labellum multo minus, brevi-unguiculatum, 

 saccatum, aut simplex aut obscure trilobum, basi callo humili lato ac longo sulcato 

 praeditum, dense papillosum; gynostemium pro flore satis conspicuum, stelidia biapiculata 

 v. bipartita, filamentum simplex, anthera mitrata, pes gynostemii excavatus. — Caulis 

 satis validus, sulcatus, pluriarticulatus, foliosus. Tota planta habitu omnino Dendrobii 

 cujusdam ex affinitate D. veratrifolii. Flores patentes, teneri, in racemum secundiflorum, 

 pauciflorum dispositi, longe pedicellati, bracteis longis aut mediocribus suffulti. 



Species 2 Indiae posterioris incolae. 



Nota. DifTert hoc genus a Dendrobio praecipue structura sepalorum lateralium non in 

 mentum productorum. Flores expansi potius Ipseam v. Spathoglottidem referunt quam Den- 

 drobium.
