No one has yet satisfactorily elucidated the species of Cotton. Our 

 first-mentioned species has finely canescent-tomentulose leaves and 

 branchlets, and copper-coloured wool : from the latter character it 

 should be the Gossypium religiosum of Swartz, and the G croceum of 

 Hamilton. The second, with thinner leaves of various outline, has 

 white cotton and dark seeds ; and is therefore Q. nigrum of Hamilton. 

 The third, with ample and deeply five-lobed leaves, has white cotton 

 and whitish seeds, and is accordingly the G album of Hamilton. All 

 these species were doubtless introduced into the South Sea Islands.
