Perennial. Leaves short-lobed. Petals yellow. Seeds dis- 

 connected, after removal of the cotton-fibre grey-velvety. 

 Distinguished and illustrated by Parlatore as a species, 

 regarded by Seemann as a variety of G. arboreum. Staple 

 longer than in the latter kind, white, opaque, not easily 

 seceding. Even this species, though supposed to be herba- 

 ceous, will attain a height of 12 feet. A variety with 

 tawny fibre furnishes the Nankin Cotton. 



Gossypium hirsutum, L.* 



Upland or Short-staple Cotton. Tropical America, culti- 

 vated most extensively in the United States, Southern 

 European and many other countries. Perennial. Seeds 

 brownish-green, disconnected, after the removal of the 

 cotton- fibre greenish- velvety. Staple long, white, almost of 

 a silky lustre, not easily separable. A portion of the 

 Queensland Cotton is obtained from this species. It neither 

 requires the coast tracts nor the highly attentive culture of 

 Gr. Barbadense. 



Gossypium religiosum, L.* (G. Peruvianum, CavanJ 



Tropical South America. Kidney Cotton, Peruvian or 

 Brazilian Cotton. Leaves long-lobed. Petals yellow. 

 Seeds black, connected. The cotton is of a very long 

 staple, white, somewhat silky and easily seceding from the 

 seeds. A tawny variety occurs. This is the tallest of all 

 cotton-bushes, and it is probably this species, which occurs 

 in the valleys of the Andes as a small tree, bearing its cotton 

 while frosts whiten the ground around. 



Gossypium Taitense, Parlatore. 



(6r. religiosum, Banks and Solander.) 



In several islands of the Pacific Ocean. A shrub. Petals 

 white. Seeds disconnected, glabrous after the removal of 

 the fulvous cotton-fibre, which secedes not with readiness. 



Gossypium tomentosum, Nuttall.* 



(G. Sandvicense, Parlat. G. religiosum, A. Gray.) 

 Hawaia. Perennial. Petals yellow. Seeds disconnected, 

 after the removal of the tawny cotton-fibre fulvous- velvety, 

 not easily parting with their cotton.
