210 Studies in Indian Cotton 



Bracteoles deeply auriculabe or reniform, deeply serrate, spreading in 

 fruit. Corolla yellow, petals small. Stigma heavily glandular. Capsule 

 inflated and nearly spherical with a sharp mucronate apex. 



This plant is the G. herbaceum Linn, of Todaro (16) and Gammie 

 and the G. ohtusifolium var. Wightiana of Watt (20). 



Type 3. Perennial " tree cotton " ; secondary branches ascending 

 sharply at an acute angle. The entire plant of a deep red, or purple 

 colour. Leaf with a factor greater than 3 ; frequently with an extra 

 tooth on one or both sides of the central lube. Bracteoles small, tri- 

 angular ; margins entire or with the tip dentate. Corolla deep-red. 

 Stigma eglandular. Capsule usually 3 celled, ovate. 



This plant is the Gossi/piii»i arhoreum of Linn. Sp. PI. ; Parlatore (14); 

 Todaro (16); and the G. arhoreum type of Gammie (9) and Watt (20). 



Sympodial types. 



Annuals with a few only, or none, of the lowest secondary branches 

 monopodia, the remainder sympodia ; the monopodial branches ascending 

 and the sympodia] spreading. 



Type 4. A tall plant, in later stages drooping under the weight of 

 fruit. Leaf large, with factor less than 2 ; lobes commonly 3 or with 

 two small accessory basal lobes. Young stem and leaves sparsely hairy. 

 Bracteoles small, entire or with few small apical teeth, closely enveloping 

 bud and fruit. Corolla yellow with deep-red " eye." Petals large, semi- 

 transparent. Stigma eglandular or with few glands only. Capsule 

 commonly 3 celled, ovate. 



This plant is the Gossypium indicum Lamk. of Gammie (9) and 

 G. Nankin var. bani of Watt (20). 



Type 5. An erect plant, in later stages drooping under the weight 

 of fruit. Leaf factor less than 2 ; lobes 5 — 7. Young stem and leaves 

 hairy. Bracteoles large, entire or with few small apical teeth loosely 

 enveloping bud and in fruit sometimes reflexed. Corolla yellow with 

 deep-red " eye " ; petals opaque. Stigma eglandular or with few glands 

 only. Capsule commonly 3 — 4 celled, ovate. 



Type 6. An erect plant differing from type 4 in the greater rigidity 

 the main stem and the angle at which the secondary monopodia arise, 

 in this case about 4-5°, and in the corolla which is white. The petals 

 are small, scarcely projecting beyond the bracteoles. 



Type 7. Plant erect with secondary monopodial branching, when 

 developed, sharply ascending. Leaf factor less than 2 ; flower white.
