Hab. Himalaya centrali et occidentali Garwhal! Strachey & Winter- 
bottom ; Nepal! Wallich (8. temp. pluv.). 
A large-leaved, membranous, flaccid, very much branched species, but 
distinguished by the inflated saccate incurved labellum, rather sud- 
denly terminating in a short recurved spur, as also by the long, erect, 
slender racemes, with whorled peduncles, slender capsules, and large 
pale lilac flowers. The petals terminate in long slender tails.

Garwhal, 4000-8000 ped. ! Edgeworth (8. temp. pluv.). (v.v.) 
The I. longicornu of Wallich in Roxburgh's ‘ Flora Indica,’ is not the 
plant of his Herbarium, по. 4729 in Herb. Lindley et Henslow, which 
latter differs from his description in the leaves being broader, not crowded 
towards the ends of the branches, nor linear-lanceolate ; nor does it 
agree with Wallich's description in being a fleshy species with approxi- 
mate ventricose joints, a leafy subfastigiate panicle, and an exceedingly 
long filiform spur thrice the length of the pedicel, all which characters 
agree much better with I. insignis, Wall. The yellow fragrant flowers of 
the I. longicornu, described in * Flora Indica,’ are, however, unlike I. 
insignis, and suggest its being the I. odorata, Ham. (in Don, Prodr. 
203), in the I. leptoceras, Wall., of which one Nepal specimen in 
Herb. Henslow (4760) well agrees with Wallich’s character of I. longi- 
cornu. It is evident, I think, that three species have become mixed up
