AD FLORAM INDICAM (BALSAMINE E). 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 I. laxiflora, bicornuta, sulcata, and Roylei. When the 
flowers are simply racemose, it is not easy to distinguish this from 
I. laxiflora.
