allied to the Ternstrcemiacese) ; Corchoropsis (one of the 

 Tiliaceae) ; Tripetaleia (doubtfully placed among the 

 Oleaceae) ; Stephanandra (affinity also doubtful, probably 

 belonging to the Rosacese) ; Ceraseidos (one of the 

 apetalous Amygdalaceae plants) ; Platycaria (one of the 

 Juglandese) ; ScMzocodon (Polemoniaceae) ; Conandron 

 (allied to Ramondia) ; PhyllostacUys (Bambuseae). Accord- 

 ing to the author, the bamboo-stems of commerce, as also 

 the pepper-canes as they are called, are obtained from the 

 Bambusese, which are common in Japan, and of which 

 there are 1 5 ; they seldom, however, flower, and therefore 

 the species are but imperfectly known. 



Royle has drawn up some remarks upon the vegetation 

 of Afghanistan, Cashmere, and Thibet, from the truly 

 very inconsiderable collections of Vigne (Travels in 

 Cashmere, Ladak, Iskardo, &c., by G. T. Vigne, 2d edit. 

 London, 1844, 8vo, Appendix). However, these frag- 

 mentary reports are of interest, on account of Royle's 

 intimate acquaintance with the botanical character of the 

 Himalayan mountains, the use he has made of other 

 sources, and the general plan of his investigation. Thus 

 he starts with the question of what constitutes the northern 

 and western boundaries of the indigenous plants of the 

 Indian plains. He considers it as an established fact, 

 that the western boundary of the Indian flora along 

 the Indus is formed by the Soliman mountains, and, in 

 fact, the influence of the monsoon and summer-rains, 

 upon which the vegetation of the tropical plains is de- 

 pendent, disappears entirely in the district of this meri- 

 dional chain, on the line from Kelat to Peshawar. Rovle 



t/ 



is especially indebted for the observations upon the western 

 localities of Indian plants to the traveller Falconer, who 

 is now his successor in the Botanic Garden at Saharun- 

 pore. The latter found Butea frondosa even on the 

 Jhelum, the most westerly of the Punjab rivers ; the 

 Chenopodese of northern India accompanied it as far as 

 Peshawar. Above Attock, on the Indus, the charac- 

 teristic plants of the British Himalaya again recurred.
