on cotton cultivation in West Africa. The following may be con- 

 sulted as having a bearing very possibly on the present species :

AMERICA. Mention has been made of the fact that the moqui American 

 cotton of Arizona is a form of the present species G. punctatiim, var. j^c-cmi 

 Jamaica. Drummond found it also in Alabama, and Palmer and cotton, 

 many other collectors have brought it from Mexico and Florida. 

 There can be thus no doubt that a series of forms quite as numerous 

 and important as those mentioned in connection with Africa 

 originated in America and played an important part in the evolution 

 of the prized cottons of that country to-day. This subject has, 

 perhaps, been sufficiently indicated in the remarks made under the 

 opening paragraphs regarding the present group of fuzzy-seeded 

 cottons, the more so since it will have to be taken up again under 

 G. hirsutum. 



The moqui cotton of the Indians of Arizona (of which a specimen 

 has been supplied to me by Mr. Lyster H. Dewey) is, as already 

 stated, but one of the many cultivated states of the present species 

 except that the leaves are larger than is customary. It may be 

 described thus : Young shoots thick fleshy pilose, later firm, Descrip- 

 angled and glabrous. Bracteoles very slightly united, glabrous and tlon - 

 smooth, bractlets only rarely visible. Flowers small lemon yellow, 

 tinged purple, but claws not coloured. Closely allied is the so-called 

 Texas wool which has medium- sized almost glabrous leaves and 

 large coarse seeds with a dark green fuzz and short dirty-greenish 

 coarse wool. 



A further sample, said to be also ' Moqui Indian ' cotton, has been 

 sent to me from Egypt by Mr. W. Lawrence Balls, and has pre- 

 served in the minutest detail its characteristics with that grown at 

 Washington from Arizona seed. 



The Egyptian form is perhaps a little more pilose than the Moqui 

 Arizona. Mr. Balls observes that the moqui cotton plant is of 

 special interest in Egypt on account of its remarkably early maturity.
