This plant was found on the mountains of Sirmore by Dr. Govan, and in Kamaon by Robert Blinkworth, one of 

 the plant-collectors of the Honourable Company's Botanic Garden at Calcutta, where it was introduced by him and is 

 now thriving luxuriantly. It is a very pretty shrub, producing a profusion of sweetly scented flowers.
