KEY TO GENERA 
1. Stigmata terminal, on top of a truncate or subtruncate 
column and at right angle to rostellum; hence, they appear

la. Stigmata anterior, either beneath the rostellum or on both 
sides of it; hence, they appear vertical ............... 8 
2. | Flowers not resupinate, hence, lip uppermost; dorsal sepal 
connate with lateral sepals for a neglibible distance at base 
and adnate to filament of anther; clinandrium formed by a 
narrow, hyaline margin, free from filament of anther; pol- 
linia with distinct caudicles ............-. 1. Nothostele 
2a. Flowers resupinate, hence, lip lowermost, dorsal sepal free 
from lateral sepals; clinandrium well-developed, fused with 
filament of anther; pollinia without caudicles ......... 3 
3. Petals free from dorsal sepal; rostellum deeply bifid to 
bicuspidate; plants with a single, sessile, cordate-sub- 
rotund leaf enveloping the stem ........... 2. Discyphus 
3a. Petals agglutinate with dorsal sepal; rostellum not divided; 
plants either aphyllous at flowering time or with well- 
developed, cuneate to petiolate leaves .............++. 4 
4.  Rostellum soft, short, broadly triangular with an apical 
fovea; lip fleshy, cochleate in front .... 3. Sauroglossum 
4a. Rostellum rigid, more or less cartilaginous, sharply 
pointed; lip membranaceous, never cochleate in front ...
