membranous acuminate, shorter than the ovary ; lateral sepals 

 spreading-deflexed, lanceolate-ovate acute concave, 1'2-1'4; cm. 

 long ; odd sepal erect galeate, mouth ovate acute, produced 

 dorsally into a conical acute spur, 0*5 cm. long ; petals ascending 

 falcate-oblong, widened at the apex and irregularly lacerate- 

 dentate, rounded in front at the base, 0'6-0*7 cm.' long ; lip 

 pendulous, with a linear-filiform claw, 4-H cm. long, dilated and 

 laciniate at the apex ; rostellum elevated 81obed, lobes equal in 

 length acute, the middle placed farther back ; anther strongly 

 resupinate ; gland solitary subquadrate. 



Described from several living and dried specimens. 



A very curious and distinct species of a group of which we 

 are yet far from knowing the limits of variability. The long lip is 

 very remarkable, and as it sways about in the wind suggests a 



possible means of attraction for insects.
