The flowers oi this handsome species are of rather a dark yellow, the lij) having
a large purple blotch Jiear its centi-e, and its edges being of a paler yellow than the
rest of the flower. It; has been collected only once in Sikkim; and in Assam, the
Kiiasia Hills, and Upper Burinah, where it occars more plentifully than in Sikkim, it
is by no means abundant. Specimens were collected many years ago in Nopal by
Wallich, and in Kamaon by Straehey and Winterbotham; but of late years it does
not appear to have been found in the Western Himalaya.
