 A very handsome and distinct genus of Ascleptadece remarkable for 

 tbe great elevation at wbicb it grovvs. It was discovered in damp 

 oak and laurel forests on Tonglo and Sincbul, mountains of Sikkim by 

 myself in September 1848. It is allied to Marsdenia, from which it 

 differs in the large rotate corolla, like that of n. Hoy a or Heterostemma. 

 I have named it in compliment to W. J. Treutler, M.D. F.L S a 

 native of Sikkira, who presented to Kew a valuable collection of tbe 

 plants of that country, amongst which were fine specimens of this 

 species.
