The cotton genus includes approximately 50 species distributed globally in seasonally arid regions of the subtropics.One notable aspect of this diversity is that four different species,two each in Africa-Asia (G.arboreum and G.herbaceum) and the Americas (G.barbadense and G.hirsutum),were independently domesticated for their extraordinary single-celled,epidermal seed trichomes ("fiber").Gossypium species exhibit remarkable morphological diversity,ranging from herbaceous perennials to small trees and displaying a great variety of floral and vegetative features.
