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.

 The J. longicornu of Wallich in Roxburgh's * Flora Indica,' is not the 

 plant of his Herbarium, no. 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 wi*h J. insignis, Wall. The yellow fragrant flowers of 

 the /. longicornu, described in ' Flora Indica,' are, however, unlike /. 

 insignis, and suggest its being the J. odorata, Ham. (in Don, Prodr. 

 20.3), in the /. leptoceras. Wall., of which one Nepal specimen in 

 Herb. Henslow (4760) well agrees with Wallich's character of /. longi- 

 cornu. It is evident, I think, that three species have become mixed up
