veloped median tooth. Pollinia 2, subglobose to ovoid, 
esulcate on a short rudimentary stipe. Lip conical to 
saccate, more or less laterally compressed, ecallose in- 
side, the anterior wall much thickened, especially toward 
the apex. 
Inflorescence axillary, elongate, from several- to many- 
flowered. Flowers all open at the same time, quaqua- 
versal. The whole rachis is alate-ribbed. 
T'uberolabium differs from Saccolabium Bl. in the gener- 
al habit of the plants, in the short differently proportioned 
column, in not having an elongate rostellum, and hence 
in the structure of the pollinia. T'’rachoma Garay differs 
from Tuberolabium in the footless column and in the 
short, distinctly incrassate, more or less club-shaped, 
tew-tlowered and congested inflorescence. 
It should be noted that the illustrations of the column 
in Saccolabium odoratissimum and Saccolabium erosulum 
by J.J. Smith are incorrect. Saccolabium Quisumbingu 
L.O.Wms. is identical with Tuberolabium kotoense 
Yamamoto.
