type is repeated on a smaller scale in Duthie's 
Asirgarh Fort and in Wight's No. 1702, and on „ „. 
scale in the slender form which is prevalent in the southern and 
- 1 era part of the area. How far those differences are due 
to the conditions of the habitat can only be decided in the tield ; 
but they certainly suggest edaphic influences, such as the conditions 
of soi> and water snpply. According to Mal.-olms-H., rho Rasa- 
grass, m the Deccan, affects particularly the trap, more or less 
avoiding the granite, so much so that he was able to trace the green- 
stone dykes across the granite by the luxuriance of the grass, whilst 
Fernandez writes that it grows on the hill sides as well as on 
plateau land and m periodically flooded plains, all of which indeed 
implies a considerable diversity of local conditions. Still it is 
noteworthy that m the ample material at my disposal the 
pactmodes type is not represented from any point south of 18° N.
