CXXY. OECHIDACE^, 713 



adnate to the side lobes of tlie rostellum ; pollinia granular, wath short 

 caudicles and exserted naked glands ; staininodes lateral, small, I'ounded 

 or auriculate. Stigmas sessile or subsessile, more or less confluent, 

 often pulvinate. Eustellum 3-lobed ; middle lobe subulate or tooth-like, 

 situated between the anther-cells ; side lobes short. Capsule ellipsoid 

 or oblong. — Distrib. Throughout the N. temperate regions and in the 

 tropics of Asia and Africa, chiefly in the mountains ; species 60 or 70. 



I have followed Kraenzlin in rehabilitating this genus, a course which has been 

 followed in Dyer's recently published ' Flora of Tropical Africa.' It is drstinguished 

 from Hahenaria by the short, more or less confluent stigmas.

 with the side arms of the rostellum channels or tubes for the caudicles 

 of the pollinia ; pollinia grai\ular, with short elongate caudicles and an 

 exserted naked gland ; stigma 2-lobed or extended into 2 short or 

 elongate often clavate papillose processes ; rostellum 3-lobed, the mid-
