FROM DAKJEELING TO TON GLO. 125

B. polystachya, Wedd. Ad /000 ped. alt. Fruticosa. Folia 

 ovato-elliptica acuta aut acuminata regulariter ac leviter serrata supra 



w 



imnutissime pilosa vel glabrata subtus fere glabra saepe albescens, 

 conspicue trinervia. Racerai fructiferi densi ramosi paniculati. Folia 

 opposita : interdum omnia alterna sparsa ! !

These three Boehmerice (together with the low-level B. Hamil- 

 toniana, Wedd., which is not seen above 7000 ped. alt.) are 

 all reckoned by "Weddell as varieties of his B. platypliylla. They 

 appear to me very distinct ; and I see in India no intermediate 

 forms whatever. 



Pouzolzia indica, Gaud. 7000-8000 ped. alt. 



Common. 



Chamabainia squamigera, Wedd. 7000-8000 ped. alt. 



- 



Abundant. 



Memorialis hirta, Wedd. (inclusa M. quinquenervi, Ham.). 7000- 

 8000 ped. alt. 



Common. 



I collected no fig. Dr. Hooker states that one species ascends 



to 9000 feet on the outer ridges of Sikkim. 



* 



EUPHORBIACE^. 



Of this large order so abundant at lower levels, I only noticed 

 one tree above 7000 ped. alt., ascending to 9000 ped. alt., viz. 



Mallotus oreophilus, Mull., Arg. 



At these high levels I do not recollect that I have ever col- 

 lected Euphorbiaceae. Sarcococca pruniformis, Lindl., I have seen 



7000 



7000-9000 ped. alt. Frequent. 



QUERXALES. 



Quercus lamellosa, Smith, is common in Darjeeling and up to 

 8000 feet. . Q. annulata?, referred to by Dr. Hooker at p. 165, 1

did not collect. 



Castonopsis tribuloides, Alph. DC, is common in Darjeeling at 

 7000-7500 ped. alt., but does not extend much further up on the 

 ridge. Quercus Andersoni (nov. sp., Hook, f., as Dr. King tells 

 me) has leaves so exceedingly like the Castanopsis, that the 

 natives reckon it the same tree, and the greater part of the 

 "Chestnut'' supplied for years past from the Tonglo ridge for 

 building-purposes to the station turns out to be from this un- 

 described oak. This oak was noticed last year by Dr. King and
