ifROM DARJEELING TO TONGLO. 135 



* 



vine abundant throughout the Darjeeling station (and district at 

 5000-10,000 ped. alt.), and abundant all the way to Tonglo, but, 

 I believe, quite undescribed. Though so common in the station, 

 it never flowers till it has attained its full size ; it is the largest 



vine I am acquainted with, and flowers at the top of the tall trees 

 when its stem is a foot in circumference. I append an imperfect 

 description, my good specimens not being at hand. 



Vitis, sp. Folia primordialia indivisa ovata valde acuminata : caetera 

 tripartita; foliola petiolata 4-8-pollicaria late elliptica basi cordata 



apice obtusa vel subito breviter acuminata, margine continuo minute 

 denticulate, supra glabrata subtus minute pilosa venis venulisque 

 conspicue elevatis retigulatisque. Foliola lateralia valde secunda fal- 

 cata basi uno latere auriculato-cordata. Cirrhi bifidi. Cymae magnee 

 compositae ramis angulatis divaricatis.

Abundant ; now in flower. 



The Ehododendrons are now (Sept.) not in flower. On Tonglo 

 from 9000 feet upwards, Rhododendron arhoreum is the prevailing 

 tree, or rather giant bush. I collected also at 9000 feet R. bar- 



W 



There 



also grows here R. argenteum as mentioned by Hooker (which I 

 have collected on this ridge on other occasions), and probably one 

 or two species more. R. arhoreum varies a good deal in the tinge 

 of its flowers, and has been supposed to include two or more 



species 



Eutacejs. 



BOENNINGHAUSENIA ALBIFLORA, Reich. 8000 ped. alt.
