This handsome shrub is furnished with many branches and an abundance of pale-green, glaucous foliage. It pro- 

 duces opposite, axillary peduncles, each of which bears three elegant flowers, remarkable on account of the large and 

 scariose calyx in which the white corolla is almost hidden. It was found on the Sirmore mountains by John 

 Forbes Royle, Esq. of the Honourable East India Company's Bengal Medical Service, and thence introduced # 

 into the botanic garden at Saharunpur ; it was also sent by him to the Calcutta garden, where it thrives well, and 

 blossoms in the cold season. The only time I ever met with the plant in its wild state was in April 1825, on one of 

 the mountains, which confine Deyra Dhoon (the valley of Deyra) to the northward. 



, I have sincere satisfaction in dedicating this new genus to my valued friend Mr. Royle, whose claims as an excel- 

 lent botanist fully entitle him to that compliment. How eminently the garden at Saharunpur has benefited under 

 his charge, is manifest by the numerous improvements and additions to its riches, which it owes to his indefatigable 

 zeal and talents, and which are well known to the Government of Bengal, as well as to all who have visited the 

 western provinces of Hindustan. But independent of having the care of this most useful establishment, he is likewise 

 the founder of a nursery for medicinal and alpine plants generally, on the Chaor mountain of Sirmore, which has 

 already proved of the greatest service. It is not, however, botany alone to which he has devoted his talents ; there 



■ is not a branch of natural history in which he has not acquired a high degree of proficiency. To pursuits of this 

 nature he is devoting every moment of leisure, which his extensive professional duties aflxjrd him, with a degree of 

 ardour and success, which is far beyond my feeble praise, and which must soon place his name high among natu- 

 ralists. It will be observed, that in expressing my sentiments above, in the dedication of the genus, I have adopted 

 the words of the celebrated Professor Kunth, on the occasion of his namlnaf the genus Lbidleya after a very dear and 

 mutual friend of us both, to whom I am indebted for the elegant dissections of the accompanying plate. 



I cannot allow this opportunity to pass without expressing HUblldy to Professor Kunth and M. Alphonse 

 Decandolle my grateful acknowledgments for their invaluable personal aid in the arrangements connected with the 

 Herbaria under my charge, by which I am at present benefiting.
