HOLE : SOME INDIAN GRASSES AND THEIR (ECOLOGY. 4<\) 



species, which give no such indication. At the same time probably no plant community 

 consists entirely of indicators, considering the term in the present narrow sense, and hence 

 iu our descriptions of communities we must record the constituent species as we find them, 

 whether they be indicators or indifferent. 



Moreover it is only by studying these so-called indifferent species in their various 

 habitats that we get a correct idea of the conditions necessary for their development. 



Plates II — XII inclusive will give an idea of the physiognomy of the various com- 

 munities of grassland and woodland which have been briefly indicated above. 



44. As regards furnishing a complete ex- 

 planation as to why each of the individual species mentioned is. in nature, able to form a 

 constituent part of the various communities indicated above, under the conditions ruling in 

 this locality, it is perhaps hardly necessary to point out that this will only become possible 

 when the cecology of each individual species has been thoroughly worked out in detail, and 

 this has not yet been done.
