8-nerved. Petals cuneate-spatulate, obtuse or subacute, 
about 19 mm. long and 11 mm. wide, 5-nerved. Lip ad- 
nate to the column nearly to its apex; lamina simple, 
obovate-reniform, fleshy, densely cellular-papillose on 
both surfaces, with the truncate anterior margin lightly 
retuse (more markedly so in the very center), about 16.5 
mm. in greatest length and 25 mm. wide, remotely bical- 
lose at base. Column abbreviated, very stout, dilated up- 
ward, semiorbicular-indented in the middle of the apex. 
Pollinia four,strongly complanate, obliquely semiglobose. 
Kpidendrum latisegmentum appears to lack South 
American allies. It recalls the Central American /. 
Brenesu Schitr., but differs in its longer leaves and larger 
flowers. In habit it recalls J7. jamaicense Lindl., but has 
larger flowers, dissimilar petals and a densely papillose lip.
