Hab. Saigon: Haffner ! v.v. 
A very singular plant with an erect stiff stem emitting roots 
at intervals. Leaves short and fleshy, channelled above and 
strongly keeled, the keel running downwards into stem, red 
edged with a few red spots. The lip has the lateral lobes 
adnate to the sides of the column. Between them, at the 
entrance to the spur, is a curious glandular body with a linear 
median bar, and a woolly mass on each side. The epichil is 
semiovate, ending in a narrow point which bears a comb-like 
fringe on each side. The column is remarkably broad. The 
anther cells are widely separated by a broad connective. The 
pedicel is square broad and truncate, the sides curved up in the 
form of two horns, the disc large hemispheric and excavate 
below.
