FEOM DAHJEELING TO TOFGLO. 119 



List of Plants collected between Darjeeling and Tonglo, at 7000 



feet or upwards above sea-level. 



Gramhste^. 



In Darjeeling station (7000 ped. alt.) and on cleared ground 

 to 8000 feet are prominently seen JEulalia nepalensis, Trin., Pol- 

 linia, sp., Poa subsecunda, Lam. ( = Pragrostris atropurpurea auct.), 

 Muehlenbergia sylvatica, Torrey, Agrostis vulgar is, With., A. alba 9 

 Sehrad. The last two mag be introduced, as also Holcus lana- 

 tus, L., Dactylis glomerata, L., Poa annua, L., which are common. 



in the station. 



In the woods at 7000-9000 ped. alt. are Isachne miUacea, 

 Roth., Digitaria, sp., Oplismenus compositus, Rcem. et Sch., Cen- 

 totheca lappacea, Desv. 



At 9000 ped. alt. Avena Junghuhnii, Biise ; and thence to 



10,000 ped. alt. Agrostis nervosa, Nees (which hardly differs from 



-4. alba, Sehrad.). And on the summit of Tonglo, at 10,000 feet, 



occur Avena alpestris, Host., Calamagrostris ciliata, Nees, Bromus 



conflnis, Nees, Stipa orthorapTiium, Steud., Olyceria tonglensis 7 

 nov. sp. 



The small bamboo referred to by Dr. Hooker under the na- 

 tive name Praong abounds, covering large spaces. But other 

 grasses, from 7000-10,000 ped. alt. on these Sikkim forest- 

 ridges, are rather rare. There are many grasses at 0-2000 ped. 

 alt. ; and, again, several alpine grasses come in at 12,000 ped. 

 alt. and upwards. 



Glyceria tonglensis, nov. sp. Glabra, 4-pedalis. Panicula diffusa, 

 ramis verticillatis insequalibus, fructu arete deflexis. Spiculae 4-8- 

 florae. Glumae omnino argenteo-scariosse. Palea inferior valide. 5- 

 nervis, margine argenteo-scariosa. 



Species Glyceria (Atropidi) distantly Mert., Koch, proxima. Differt 



gluinis argenteis j palea inferiore valide 5-nervi. 







Cypebace^:. 



Cyperus, which so abounds at lower levels, is hardly seen in the 

 forest from 7000 to 10,000 feet— except in the clearings, C. vulgaris, 

 Sieb. ; and I collected at this level no other genus in the order 

 except Cares. Cares indica, L., is plentiful from Darjeeling 

 station to Tonglo top. I gathered C. fusiformis, Nees, at 9000 

 feet, and Cfoliosa, Don, on Tonglo top at 10,000 feet. Cype- 

 raceee are certainlv rare in the forest at 7000-10,000 feet.
