SECTION II: ANALYTICAL KEY TO SPECIES 77 



restoration (partial at least) of its supposed American form, but 

 to discover how far a pure wild species can be evolved by these 

 means alone toward an industrial state. 



SECTION II. Fuzzy-seeded Cottons with United Bracteoles. 



BRACTEOLES united below, never clawed, attached to the apex of 

 the pedicels by a semicircular (or horseshoe-shaped) constriction within 

 the auriculate base ; EXTRA-FLORAL GLANDS not possessed of definite 

 external glands, though internal ones, on the base of the calyx-tube, and 

 alternating with the bracteoles, are usually present and conspicuous ; 

 SEEDS with an inner coating of velvet (fuzz) and an outer of wool (floss), 

 firmly adherent to the seed; PETALS with purple claws (cf. pp. 163-4). 



Perennial or annual shrubs, with the leaves 5-palmatifid and 

 mostly stellately tomentose, occasionally pilose with long weak hairs, 

 or both conditions present, the pilose hairs appearing mostly on 

 the branches, petioles, and veins, or in other forms with the leaves 

 almost glabrescent and leathery in texture. One or perhaps two 

 members of this section have been recorded as met with in a wild 

 condition, the others are undoubted cultivated plants derived very 

 possibly from four specific types G. arboreum, G. Nanking, G. obtusi- 

 folium, and G. herbaceum. They are met with on the shores of the 

 Mediterranean, through Africa, Egypt, Arabia, Asia Minor, Kurdistan, 

 Persia, India, China, Japan, and the Malay Peninsula and Archipelago.
