320 Prof. Don's Account nf the Indian Species cj/"Jiinciis and Lnzula. 



The Luzula spicata, which occurs on the mountains of Scotland and the 

 North of England, at an elevation of from 2000 to 3500 feet above the level 

 of the sea, is met with at higher elevations throughout the central and south- 

 ern parts of Europe, and abundantly in the polar regions of Europe, Asia, and 

 America, as high as 71 degrees of latitude. It is also found on the chain of 

 the Caucasus in 42° north latitude, l)eing exactly in the same parallel with its 

 most southern limit in Europe, and likewise on the Altai mountains, near the 

 sources of the Irtish in 51" north latitude ; and it may probably extend along 

 some portions of the table land intervening l»etwcen that vast range of moun- 

 tains and the Himalayas. 



The present plant is from Kunawur, in about 31° 33' north latitude, nearly 

 eleven degrees more to the south than any station previously recorded for 

 Ltizula spicata.
