216 ORCHIDACE&. [ POGONIA. 



appearance of the flower-scape, occasionally coetaneous. Flowers 

 solitary few or several, racemose, often pendulous, on scapes rising 

 from the tuber. Sepals subequal, narrow, connivent or spreading. 

 Petals like the sepals. Lip adnate to the base of the column, some- 

 times slightly saccate at the base, rather narrow, the lower portion 

 convolute round the column ; lateral lobes small, usually triangular ; 

 apical lobe flat, ovate or orbicular, entire, or fimbriate. Column 

 elongate, clavate upwards ; stigma anticous, oblong or orbicular. 

 Anther more or less incumbent, substipitate ; pollinia 2 or 4, 

 elongate, powdery, often coherent, without caudicle or gland. 

 Species about 80, in Trop. Asia, America and Africa. The above 

 characters apply only to the section Nervilea, to which all the 

 Old World species of Pogonia belong, and which differ by flowering 

 before the leaves appear. All the other species, except one in 

 Japan, are found in the New World, and their flowering stems 

 bear leaves. 



Leaves many-nerved ; floral bracts longer 



than ovary, deflexed ; lip slightly saccate 



at the base . . . . . . 1. P. GAMMIEANA.
