SECTION III : SHORT STAPLE UPLANDS 



G. hirsutum ; similarly mexicanum x hirsutum the opposite con- 

 dition namely, a hybrid with the mexicanum characters strongly 

 marked. 



UPLAND OB SHORT STAPLE COTTONS OP AMERICA. 



I. MEXICAN SERIES. (1) ' Durango/ n. 599, seed procured from Short 

 Gobiano del Estado de Durango and grown at Washington. A large uplands- 

 broad-leaved plant with young parts hairy ; bracteoles ciliate, Durango. 

 glabrous within, and having the punctations arranged along the 

 veins, bractlets not seen ; flowers large, pale yellow, only partially 

 tinged with purple ; calyx smooth glabrous, 3-veined, teeth con- 

 spicuous deltoid; seeds beaked, large, coarse, with grey-green 

 bearded fuzz and fairly long silky floss (see Plate No. 41). A hybrid 

 strongly G. mexicanum x hirsutum. 



(2) ' Mexican Cotton,' n. 2. Is a plant with flowers considerably 

 smaller than preceding but bracteoles with very long teeth. Is a 

 hybrid of G. mexicanum x hirsutum. 



(3) ' Molango,' n. 615, seed procured from Esteban Cruz, Molango. 

 Tepehuacan Molango, grown at Washington. A much more hairy 



form than either of the above, leaves broad with lobes short and 

 sinuses thrown up in folds ; stipules very large, broad ovate, suddenly 

 awl-shaped; bractlets within and alternating with the bracteoles, 

 occasionally present. A hybrid of G. hirsutum approximating closely 

 to G. punctatum. 



(4) ' Mexican Cotton ' from the ' Secretario de Fomento,' City of 

 Mexico, n. 5. Is a much-branched form with long spreading hairs 

 on the round smooth stems and all the young parts ; leaves often 

 quite entire or only angled the others 3-lobed on the apex ; flowers 

 large, tinged with purple ; external gland obscure ; bracteoles 

 ovate oblong, with the central teeth much longer than the others ; 

 bractlets not seen. This comes much nearer G. hirsutum than to 

 G. mexicanum. 



(5) ' Mexican Cotton ' from Mexico, n. 6. Leaves large, from 

 3-7-lobed (much like Durango above), hairy on the very young 

 parts ; flowers pale only, faintly tinged with purple ; bractlets not 

 observed ; seeds large, coarse, coated with woolly white fuzz and 

 fairly abundant floss, somewhat harsh. A hybrid of G. mexicanum 



x hirsutum.
