THE tract of the Western Himalaya lies between 28°45’ to 36° N. lat, and between 
71° 30’ to 80°40’ E. long.* It extends from Kumaon on the east to the North-West 
Frontier territories of Gilgit, Chitral and Hazara, and its total area nearly equals that 
of California (United States). The outer ranges rise abruptly from the great tropical 
plain of North-West India, and usually to elevations within the limits of the Temperate 
Zone; whilst on the higher inner ranges, which extend up to above the level of forest 
growth, a rich Alpine flora is met with. Beyond, and in the neighbourhood of the main 
axis of the chain of the West Himalaya, are the lofty snow-clad peaks, some of which 
such as Nanda Devi in Kumaon, and Nanga Parbat between Kashmir and Gilgit, attain 
an altitude of over 25,000 feet above the sea, 
The number of species at present known to occur within the limits of the Western 
Himalaya is 173, Of these fifty-nine are epiphytes and 114 are terrestrial, and there 
are 24 endemic species. Forty-five genera are represented, none of which are endemic. 
The following table shows the distribution of the genera in other parts of the 
world : —
