leaved plants are very common and one plant (E 468 of II) 

 selected in 1910 bred true to this character in the year 1911. 

 In size the leaves of the Barmeli and the Nepali varieties are 

 larger than the other Bengal types. The colour of the leaves 

 of the black seeded types (I, II) is slightly darker than that of 

 the chocolate and yellow types (III, IV). The distinctive 

 colour of the Nepali and American varieties is due to absence of 

 pubescence. The black seeded types (I, II) have bullate leaves, 

 which have hitherto distinguished them from other types, but 

 in a natural cross (E 426 of II), this character has been found in 

 other combinations. The upright types have upright petioles 

 from which the leaflets are deciduous. 



'3c. — Pubescence. 



The differences in the hairiness of Soy Bean varieties may 

 be classed under two heads, the colour and the quantity of the 

 pubescence. As regards its colour Piper and Morse (9) have 

 shown that tawny pubescence is a Mendel ian dominant to white 

 pubescence. With the exception of Barmeli (type V), in which 

 the hairs become whitish as the plant ripens, all the Bengal types 

 have tawny pubescence. Differences in the quantity of the pubes- 

 cence do not appear to have been noticed in America, but in 

 the Bengal types I — V the leaves differ from the American varie- 

 ties and Nepali (type VI) in being covered with soft upright 

 hairs on their upper surfaces, whereas the upper surfaces of the 

 leaves of the latter types are covered with closely adpressed hairs. 

 The American varieties and Nepali can be distinguished at a dis- 

 tance from the fully pubescent types by the darker green colour 

 of their leaves. 



3d. — Flower. 



1. Morphology.— The flowers are produced on short axillary 

 or terminal racemes which in Barmeli are sometimes longer 

 than in the other types. 



The flowers of all the varieties grown at Sabour measured 

 from 6 to 7 mm. The flower colour of the Bengal types I— V was 

 purple, though the Barmeli type is slightly redder. The Nepali
