Characters of Saccolabium, but with a large dorsal callus 

 in the spur below the column; differing from Cleisostoma in 

 the spur not being septate. — Sp. about 30; 18 in Fl. B. Ind. 



I have stated, in Fl. B. Ind. (vi. 61), that it would be better to unite 

 Cleisostoma and Sarcanthus with Saccolabium. Here, in accordance 

 with Dr. Trimen's views for this Flora, I follow the 'Genera Plantarum.'
