85. DE^DROBllJM bica7nera(Km ; caulibus fusiformibus, folils linearl-lan- 



ccolatis apice oblique biclciitatis, pedunculis lateralibus squainatis 4-floris, 

 floribus concavis subcarnosis, scpalis pctalisque subrotuntlo-ovatis acutis, 

 labelli trilobi lacinia interinediii rotundata apiculata carno.sa lateralibus trian- 

 gularibus acutis breviore, columnai facie cxcavata semibiloculari. 



A native of the north of India, whence it was brought by 

 Mr. Gibson for the Duke of Devonshire. I am indebted to 

 George Barker, Esq. of Birmingham, for a specimen. The 

 stems appear to grow nearly upriglu, and are rather short, 

 fusiform and furrowed when old. The flowers are a little 

 smaller than those of Maxillaria stapelioides, and like them 

 in form ; their colour is dull yellow, spotted and streaked 

 with purple. In the specimen 1 examined the flowers grew 

 in fours, on a very short peduncle, closely covered with 

 ovate concave bracts, speckled with purple. The excavation 

 of the face of the column, and its division into two cells are 

 remarkable. 



86. GONGOR A nlgrltu ; bypochilii convex! cornubus lateralibus ascendentlbus 



abbreviatis aristis setaceis, epichilio acuminato apice uncinato breviore. 



This is much the darkest of the Gongoras, the appear- 

 ance of the flowers being like that of the deepest puce- 

 coloured velvet. It is very nearly the same as G. atropur- 

 purea, but the lower half of the lip is convex not concave, 

 longer than the upper half not shorter, and the horns at its 

 sides are very short. It was imported from Demerara by 

 S. Rucker, Esq. Jun. who informs me that the smell is quite 

 diff*erent from that of G. atropurpurea.
