This embraces the forms of the so-called Sea Island Cotton, in 

 fact, most of the Long Staple Cottons of the United States of America 

 and of Egypt. Its separation from G. vitifolium has been made 

 from industrial rather than botanical reasons. By some authors 

 G. barbadense has been made, but incorrectly, to include also the 

 Bourbon cottons. 



Descrip- A shrubby perennial, found only in cultivation and usually treated 



as an annual ; glabrous, or nearly so, except on the leaf stalks and 

 veins of the leaves and the under surfaces of young leaves ; leaves 

 fully half or more segmented into 3 to 5 usually spreading ovate 

 oblong acuminate lobes, central one not materially larger than the 

 others, but bearing on the vein below a distinct gland (or occasionally 

 also the lateral veins may have glands) ; peduncles usually shorter than 

 the petioles, rigid and strongly angled ; flowers not twice the length of 

 the bracteoles ; braoteoles free, ciliate and eglandular ; capsules ovate 

 acuminate, 3- or 4-valved ; seeds free from each other, ovate, beaked, 

 smooth, black, naked, except a small tuft of hair at the apex ; wool 

 long, silky, pure white, and readily separable from the seed. (See 

 Plates Nos. 45 and 46 A.) 



It may now be useful to furnish a more detailed description of this plant 

 as accepted by me : Stems round, often blue-black, smooth, glabrous, 

 interruptedly angled ; leaves in texture thick, smooth, usually drying in the 

 herbarium into greenish-grey, not the brown colour so constant in G. 

 brasiliense, often with a purple tinge when fresh (especially along the 

 prominent midribs, which look as if composed of three folds), in size the 

 leaves are 3 to 5 by 2 to 4 incnes, in main shape ovate oblong, cordate, 

 | segmented into 3-5 lobes which normally ascend, ovate oblong, acuminate, 

 the sinus thrown up in a fold, glabrate, with a few hairs on the veins (the 

 tendency to become glabrous, to have large broad cordate leaves, with 

 5 spreading lobes, marks the advance from G. vitifolium through G. barba- 

 dense to the variety of this species distinguished as maritima) ; stipules 

 linear, ovate, acute, oblique ; petiole nearly as long as the leaf, often with 

 a lew long hairs. Inflorescence axillary, solitary, on special leafy shoots that 

 become much elongated; pedicels about 1 inch long, angled in maturity,
