64 FLOUA INDICA. 



malayaa botany would have long ago been established on a 

 foundation of judiciously collected facts j but unfortunately 

 his journals, though sufficient to show the ample means at 

 his disposal, were not thrown into a shape in which they are 

 available to science, nor would it have been possible to give 

 them such a form without the local knowledge which was lost 

 with their collector. Other botanists have since traversed the 

 scenes of M. Jacquemont's labours, and, more fortunate than 

 he, have been enabled to reap the well-earned reward of their 

 exertions ; but let it not be forgotten that a foreigner was the 

 first in the field, and but for his lamented decease, would have 

 stood in the very foremost rank of Indian botanists. We are 

 proud to say that the Directors of the Jardin de Plantes 

 (through M. Decaisne's good offices) have been so liberal as 

 to place at our disposal a nearly complete set of these truly 

 valuable collections, which are accurately ticketed, so that the 

 exact localities are in almost every case easily determined. 

 Our acquaintance with many of the districts where Jacque- 

 mont travelled, wiU enable us to make the best use of this 

 valuable gift, and to give to his discoveries their well-merited 

 precedence. 



6. Dr. Royle's extensive collections of Northern Indian and 

 Himalayan plants, formed the groundwork of his work already 

 noticed. A detailed account of the districts investigated by 

 Dr. Eoyle, and by his collectors, will be found in the intro- 

 duction to that work. These were chiefly the Jumno-Gan- 

 getic Doab, the upper part of the Gangetic plain, and the 

 mountains of Garhwal, Sirmur, Kanawer, and Kashmir. By 

 continental authors. Dr. Royle's Himalayan plants are occa- 

 sionally quoted as from Nipal, a mistake which leads to erro- 

 neous conclusions, and which therefore requires to be guarded 

 against. The original set of Dr. Royle's collections remains 

 in his own possession, and he has liberally placed it at our 

 disposal for examination and comparison with our own. As 

 the specimens are named in accordance with his work, we 

 have been able in every case to identify them. Dr. Royle
