Type: Stereochilus hirtus Lindl. 
Characterized by the rather long, erect column with- 
out a foot. Rostellum porrect, long, subulate. Pollinia 
4, more or less ovoid, distinct on slender stipe with a 
minute gland. Lip firmly adnate to base of column. 
Lateral sepals adnate to the sides of the lip. 
It differs from Micropera which also is characterized 
by the lateral sepals being decurrent on both sides of the 
lip, in the long column, in the differently shaped rostel- 
lum and in the number and structure of the pollinia. 
From Cleisostoma BI. (Sarcanthus Lindl.) in which it has 
been included by several students, Stereochilus differs in 
the elongate column, in the proboscis-like rostellum and 
in the four distinct pollinia.
