290 SOUTHERN FIELD CROP3 



(1) Storm-proof big-boll cottons (Fig. 138) ; 



(2) Big-boll varieties having plants of the shape that 

 characterizes the semicluster group; and 



(3) Ordinary big-boll varieties having neither marked 

 storm resistance nor semicluster shape of plant. 



Examples of storm-proof big-boll cottons are Triumph, 

 Rowden, and Texas Storm-proof. Among the semicluster 

 big-boll varieties are some strains of Truitt, Bancroft, and 

 individual plants of a number of big-boll varieties. 



Among big-boll varieties of the third subdivision are 

 the widely grown Truitt and Russell, the latter having 

 green seed. Here, too, belong Cleveland and Cook, two 

 very productive varieties, the bolls of which are sometimes 

 scarcely large enough to admit these varieties into the big- 

 boll class, where they usually belong. 



262. The Long-limbed group. In this class the plants 

 grow to large size and have long limbs with long internodes; 

 that is, they are " long jointed." Apparently this is a 

 disappearing class, represented chiefly by unimproved 

 cotton. No existing variety of notable productiveness is 

 included in this group. 



263. The Intermediate group. This group is provided 

 merely as a matter of convenience to include varieties that 

 are too nearly halfway between any other two groups to be 

 assigned to one of them. 



264. The Long-staple Upland group (Fig. 139). The 

 superior length of staple is the distinguishing characteristic 

 of this group. The lint usually measures 1 J to 1^ inches. 

 The percentage of lint in the seed cotton is low, usually less 

 than thirty-one. Examples of this group are Allen Long- 

 staple, in which the plants are tall and usually of a semi-
