AD TLOEAM INDICAM (BALSAMINEiE). 149 



in Wallich's published description, * Catalogue,' and original Nepalese 

 MSS., and that these three include that to which we now confine the 

 name of longicornu together with I. leptoceras and I. insignis. 



The best characters for this species are the erect branching habit, 

 alternate leaves, long erect peduncles, with subumbellate or shortly 

 racemose large flowers, small lateral sepals, and the labellum well deve- 

 loped into a long sac, which is either conical or broadly cylindric and 

 blunt, ending in a slender spur, and especially by the narrow capsule, 

 which forms a straight line with the peduncle, and is neither inclined 

 nor nodding. The flowers vary greatly in number, dimensions, and 

 colour. Small states are difficult to distinguish from various congeners, 

 according as their habit and the colour of the flowers inclines to one or 

 another, as to /. laxiflora, bicornuta, sulcata, and Roylei. When the 

 flowers are simply racemose, it is not easy to distinguish this from 

 I. laxifiora.

 alternis. Calcar elongatum.
