TENASSEEIM ; at Moulmein, Parish. 



Stems tufted, 1-1 in-> clothed to the base with coriaceous falcate ensiform acute

 which differ so greatly in habit, foliage and the slender column from B. palustris^ 

 that I suspect the species will prove to be generally distinct. The habit is that of 

 Dendrobium atropurpureum.
