Deiregyne Schltr. in Beih. Bot. Centralbl. 37(2): 426, 1920. 
Etymology: Deire = neck and gyne = pistil, woman, in refer- 
ence to the position of the sepals which sit per- 
pendicularly on top of ovary as if it were a neck- 
like extension. 
Sepals subsimilar, connivent with spreading apices; dorsal 
sepal partially adnate to column; lateral sepals decurrent on 
column-foot, together form a gibbous nectary. Petals agglu- 
tinate with dorsal sepal, sinuous, more or less decurrent at base. 
Lip arcuate, conduplicate at base with more or less thickened 
margins; margins of blade in middle agglutinate with sides of 
column, apex recurved. Column arcuate, partially adnate to 
dorsal sepal, basally with a decurrent, somewhat incurved foot, 
more or less sulcate in front; stigmata 2, confluent bilobed at 
apex; rostellum soft, laminar, longer than wide, from a broad 
base variously triangular, obtuse to subacuminate. Anther 
ovate, cucullate to umbonate, acute or obtuse; pollinia clavate 
with a small, round viscidium. Ovary more or less cylindrical to 
fusiform, sometimes twisted.
