I have seen but one specimen of this beautiful little species which is 
so remarkable for its slender habit, large flower, and especially the 
disproportionate size of the great white standard, that I do ner hesitate

specimen of a much larger plant, but I can indicate no obvious err 
ae ee pepe is a well-known mountain north of Simla.
