ON THE CLASSIFICATION OF CULTIVATED RICE. 13 
Sub-var. 2. Glutinous rice ( glutinosa, Lour,). 
(a) Awnless. 
he Awned. 
} (a) Long-grained. 
(6) Round-grained. 
( I ) Large-grained. 
(IL) Medium-grained. 
(III) Small-grained. 
The further sub-classification is near- 
ly the same as in the case of sub-var. 
1 and is omitted here. 
The author added that he was not satisfied with the above classifica- 
‘tion and hoped to improve it after further study; but the writer is very 
sorry to say, that S. TAyaxa, to whom we are much indebted for his con- 
tribution to the rice-classification, is no more. 
The writer has for many years taken much interest in the study of 
rice, and a few years ago had occasion to obtain numerous specimens of 
paddy from India, Burma, Siam, Ceylon and Java, in addition to those 
previotisly obtained from China and Korea, and of seeing a kind of wild 
rice growing naturally in Siam. These facts induced him to venture op 
a contribution to this line of agricultural science. 
In classifying cultivated plants we should of course consider their 
morphological characters, which are constant, but at the same time we 
have also to examine those characters, which, though not very constant or 
fluctuating considerably, are sometimes yet very important for agricul- 
tural purposes. Now in dealing with the classification of cultivated rice 
we have first to determine the principles of division. From an agricul- 
tural point of view we have two principles of classification, one the culti- 
vation, the other the utility of the grain.
