461. The yellow flowered G. barbadense (Egyptian and 

 American cotton) grows better on clay soils and in moister 

 regions. It benefits very much by free irrigation, while the 

 G. arboreum requires no irrigation and grows better on high, 

 dry and sandy soils. The G. barbadense is supposed to 

 have its origin in America and the G. arboreum in Africa. 

 The G. barbadense has more entire leaves, the upper leaves 

 being only angled, and the lower ones being 3 to 5 lobed, 

 and the lobes never supplied with supplementary teeth. 

 The Kidney or Peruvian cotton is quite distinct from the 

 other forms of American cotton such as the Sea Island, 

 Georgian and Bourbon. The Kidney cotton has its leaves 

 more deeply segmented and the seeds have the peculiar 

 character by cohering together in a Kidney shaped mass. 



462. Another variety of cotton should be here mentioned, 

 viz. the Nankin cotton, which has usually Khaki or light brown 

 lint. This belongs to G. religiosum, Linn., which is probably 

 hybrid between the G. arboreum and G. herbaceum. The 

 white flossed G. religiosum of cultivation is a good variety. 



463. The Egyptian cotton seems to be derived from G. 

 barbadense, variety hirsutum, which in its turn is probably 

 derived from the Sea Island variety of American cotton 

 which is G. barbadense, viz. maritinum. The Sea-island 

 and Egyptian cottons are both adapted for cultivation in the 

 delta of the Ganges. The Bamia cotton of Egypt which has 

 been successfully grown in India and is a hybrid between 

 G. hirsutum and G. maritinum has lint with a tinge of 

 brown. This variety requires more irrigation than other 

 varieties. G. Barbadense (or Bourbon cotton) is a perennial 

 American cotton grown as fence, or in gardens, the cultiva- 

 ted variety of which is G. maritinum. This variety also has 

 been introduced with success into India. The seeds of G. 

 barbadense are not velvety like those of Indian cottons but 

 smooth and naked, the lint being easily separated from them. 



464. The G. herbaceum is a truly Asiatic cotton and it is
