1-4 STUDIES TN INDIAN COTTONS. 



Tlie plant is the G. cernuum of Todai-o and riaininie and the G. 

 arboreum var. assamiat of Watt (32). . . . . Type 10. 



A tall plant with leaf factor greater tluui 3 ; leaf lobes 5-7, 

 stem and leaves of a deep red or purple colour ; bracteoles entire 

 oi' with few apical teeth. Corolla with deep-red ''eye," petals 

 white, tinged with phik along margin and the portions exposed 

 in the hud. (Plate Xll). 



This plant is the G. sangninemn Hassh. var. minor of Gammie 

 [lo) .. .. .. .. .. Type 11. 



In addition to the above, the following forms have since been 

 subjected to experiment. 



Monopodia! Types. 



Plant tall with long monopodial branches sharply ascending. 

 Leaf with a factor greater than 3, wrinkled. Leaf and stem covei'ed 

 with short hairs. Bracteoles triangular with margin dentate. 

 Flowers yellow oi' white. 



This group appears to contain a numbei' of type whicli. however, 

 owing to their monopodial habit it has been impossible to isolate 

 with certainty. The commonest form possesses the habit of Type 3 

 (6r. arhorexm, L'nin.), which it also resembles in the form of the 

 bracts, while the wrinkled leaf and presence of short hairs give a 

 marked resemblance to Type 2 {G. herhacenm, Linn). The relatively 

 large value for the leaf factor measurement {E) gives the leaf a 

 characteristic appearance which is fieciuently obtained in the 

 offspring of the cross Type 2 x Type 3. The group is grown 

 usually as a mixed field crop in the east of the United Provinces 

 and in Bengal. 



The types appear to differ chiefly in the density of the hairs 

 on leaf and stem and in the length of the iiiternodc and of the 

 petiole. The frroiij) compiiscs the G. nitermednini of (Jammie 

 (15). 



Sympodial Types. 



(1) Plant small with monopodial secondary branches few 

 or none. Leaves 3-5 lobed with factor less than 2. Plower
