232 WILD AND CULTIVATED COTTONS 



botanical specimens supplied, remarks : ' The semi-cluster and 

 cluster cottons are adapted to rich bottom-lands where the ordinary 

 varieties become too "weedy" in growth, that is, produce large 

 stalks with few bolls. They are grown in the bottom-lands of 

 Georgia and Alabama and in Southern Arkansas. They produce a 

 medium-sized boll with a good percentage of lint, and are productive 

 under favourable conditions. The peculiar cluster characteristic is 

 due to a shortening of the internodes of the primary or fruiting 

 branch. The secondary or sterile branch is not affected. Jackson's 

 Limbless Cotton, sometimes called African Limbless Cotton, which 

 was extensively advertised a few years ago, belongs to this group. 

 It is rarely mentioned now. It was not essentially different from 



Drake's Welborn's Pet, Drake's Cluster, and other standard cluster types that 



Cluster. j iave k een cultivated for many years.' 



Chaco. (6) ' Chaco Cluster ' Cotton from Colonia Benitz, Chaco, Argentina, 



n. 166 (seeds obtained from Marcus Brioleni), and grown at Waco, 

 Texas. Is a very hairy plant, in this respect strongly of the hirsutum 

 type, but the leaves are 3-7-lobed, the lobes broad ovate acuminate, 

 and with 3 to 5 glands on the veins below ; inflorescence crowded in 

 the condition figured by Todaro as his G. maritimum, var. poly car pum, 

 that is to say a condition in which extra flowers (2, 3 or 4 in place of 

 one) are crowded within the axils of the leaves ; seeds small bent 

 angled, fuzz imperfect, floss very woolly. A hybrid cotton G. hirsutum 

 x mexicanum. (Cf. p. 281.) 



Welborn's (7) ' Welborn's Pet,' obtained from Arkansas. This is a similar 

 form to the last, with very broad, almost glabrescent, leaves ; the 

 flowers crowded in the axils; the fruits with thick smooth woody 

 valves that often open out flatly (square across) : seeds large, obtuse 

 beaked, fuzz complete, rust-coloured and floss woolly. It is a hybrid 

 of G. mexicanum x ? hirsutum. 



Willet's HI- SEMI-CLUSTER SERIES. (8) ' Willet's Bed Leaf,' received from 



Bed Leaf, j^ ^. Willet Seed Co., Augusta, Georgia. This very remarkable 

 plant has the branches, leaf -stalks, young leaves and bracteoles of a 

 purple tint ; external and internal glands of the flower very 

 conspicuous and naked, that is to say, not protected by bractlets ; 

 teeth of the bracteoles very long, narrow, awl-shaped and fimbriated. 

 It is a hybrid with its strongest strain apparently towards G. mexi- 

 canum, though it would be no surprise to learn that the other 

 ancestor had been G. purpurascens. Bohr a century ago described a 

 red-leaved cotton with fuzzy seeds.
