difficulty. In this connection it may be noted that no differences 

 in the lengths of the flowers of the many cultivated varieties 

 have yet been observed at Sabour. In view of this fact and the 

 very numerous and marked differences there are in habit, hairiness 

 and seed characters, which will .be discussed in section 3 of this 

 paper, it would seem advisable to accept the final conclusion 

 come to by Messrs. Piper and Morse that "on the whole, we 

 are therefore inclined to believe that there is but one botanical 

 species, which has been profoundly modified by cultivation." 



3 —VARIETAL CHARACTERS OF SOY BEANS. 

 3a. — Habit. 



In germination the fleshy oblong cotyledons are carried up 

 above ground by the stout hypocotyl, which is usually of a purple 

 colour. The plumule and upmost portion of the hypocotyl is 

 hairy. The American varieties Mammoth and Hollybrook can 

 be distinguished by their stouter cotyledons and hypocotyl. The 

 first pair of true leaves are simple and cordate-cuneate in shape, 

 the subsequent leaves being alternate and trifoliate In all 

 the varieties introduced into cultivation at Sabour and on the 

 other farms in Bengal, nodules were found to be present on the 

 roots. 



The work on Soj^ Beans has not progressed sufficiently far to 

 enable us to be certain of the factors which produce the many 

 differences of habit, but it would appear that there may be two 

 principal pairs of characters, upright and reclining stems and 

 branches, short and long internodes. As regards the first pair of 

 characters, two of the varieties grown in the Sikkim Himalayas, 

 Barmeli (type 5) # and Nepali (type C>) and all of the American 

 varieties have upright stems, while the four types (I — IV) 

 usually found in the plains of India have reclining branches, 

 but of these the chocolate and yellow seeded types (III, IV) 

 have the lower part of the main stem slightly more upright than
