Desf.; and TZ. vulgare, Vill.; and the majority of the types, 
including all those of agricultural importance, fall into the group 
known as common wheats. 
Up to the sub-division of Triticum sativum, Lam., into six sub- 
species, arranged in two groups, most modern botanists are in agree- 
ment and the classification of Koernicke in the Handbuch des Getreide 
baues which we have quoted above is the one now in general use. 
From the point of view of the study of the numerous sorts of wheat 
in cultivation this classification, however, does not carry us very far. 
There are a very large number of distinct wheats in each of the six 
sub-species, and it is necessary to find some means of distinguishing 
these numerous forms. It is at this point that divergencies are to 
be met with in the literature’ on the classification of the cultivated 
wheats. These differences of opinion arise from the varying degree 
of importance assigned by investigators to the characters used 
in separating the types. None of the existing schemes of classi- 
fication appear to us to be beyond criticism, and we according- 
ly decided to make a detailed study of the characters of Indian 
wheats with a view of evolving a method of classification which 
would combine the botanical and agricultural aspects of the 
question. 
1 The systems of classification of wheats are dealt with by Eriksson in a paper entitled 
Beitriige zur Systematik des kultivierten Weizen, Die landwirtschaftlichen Versuchs-Stationen, 
Bd. 45, Heft 1 & 2, 1894.
