Novicioe Indies XII. — Description of a new genus of Orchidacea\ — 



By D. PfiAIN. 

 [Reed. 28th April, Bead 6th May.] 

 Among the Orchids of Sikkim sent to Calcutta by Mr. Pantling 

 during 1895, one of the most interesting was a singular little member 

 of the tribe Neottiese, — and within that tribe apparently most satisfac- 

 torily referable to the subtribe Limodorese — that did not seem to 

 fit into any hitherto described genus. Mr. Pantling's specimens, 

 with a figure made from a fresh plant, were sent to Dr. King, then 

 absent in Europe, for comparison with the material preserved in the 

 national herbarium at Kew. The result of this comparison was to 

 confirm the writer's conclusion. A definition of the new genus that it 

 is necessary to propose in order to accommodate the plant, w T ith a 

 description of the plant itself, are now given. The genus is named in 

 honour of Mr. R. Pantling whose devotion to the study of this natural 

 order is so well-known, and whose exertions have so largely extended 

 our knowledge of the Sikkim Orchid-flora.
