Cotton, the fibre of Gossypiton, and loosely, of other IWalvaceae and 

 Boinbacaceae. The fibre most used, and extensively cull, in ihe U.S., 

 India, Brazil, trop. Afr., Japan, W. L, &c. It is the fine silky fibre 

 enveloping the seed, and in G. barbadense and others comes clean 

 away, but in G. herbaceum and most spp. leaves a ' fuzz ' adhering to 

 ihe seed. There are many grades upon ihe market : the longest and 

 finest 'staple' is that of Sea Island, G. barbadense L., and the next 

 best Egyptian and some Brazilian and American. The bulk of the 

 supply is American ' Upland,' and the poorest qualities come from 

 India. For details see Watt, Wild and Cult. Cotton Plants of the
