216 WILD AND CULTIVATED COTTONS 



Speci- this species ; WEST INDIES : St. Lucia (J. J. Walsh named O. bcvrbadewe, 

 Linn., var. integra, Griseb. ; SOUTH AMERICA : Paraguay (Thos. Morong, n. 

 978, seeds with imperfect fuzz and leaves resembling (?. microcarpum) ; 

 British Guiana (E. F. im Thurn, n. 79 a specimen that closely resembles 

 Seemann's n. 32, and has the twigs, petioles and leaves pilose and pollen- 

 grains very distinctive. 



"West In the British Museum Herbarium there are, as usual, several highly 



Indian. instructive historic specimens in addition to some modern collections that 

 amplify the above enumeration. The Sloane Herb. (vol. 6 ff. 55 and 56) are 

 Sloane's own JAMAICA specimens of the plant he named O. brasilianum 

 (' Hist. Jam.' n. p. 67 et seq.), and these prove to be typical examples of the 

 present species the leaves densely tomentose, as also the flowers and the 

 seeds, sometimes fuzzy, at other times naked, but never united into a kidney 

 mass. Then in Petever's set of specimens (also in the Sloane Herb.) there 

 is (vol. 162 f. 289) a very tomentose plant that I take to be this species. 

 This is included in Petever's special set of Jamaica plants, but the label 

 bears the name Vaillant, and may thus have been procured from the Eoyal 

 Gardens of Paris. From Jamaica also came W. Wright's n. 40, collected 

 in 1765-77, which curiously matches exactly Sloane's specimen, and thus 

 confirms the conclusion that the tree cotton of Jamaica, a century ago, was 

 not G. brasiliense as hitherto supposed. 



In the general Herbarium of the Museum there are J. Miers' collections 

 from SOUTH AMERICA: Lima, n. 1055, Bolivia, n. 7573, Buenos Ayres, 

 n. 1220; New Granada, Voyage J. J. Triana, n. 3138/5286 ; Costa Eica and 

 Guatemala, F. C. Lehmann, n. 1912 ; POLYNESIA : Atoi, Sandwich Islands 

 (named G. incfocum), Barclay, n. 1248 (cult, in 1837). 



American. In the Herbarium, Eoyal Botanic Gardens, Edinburgh, in addition to 

 duplicates of some of the plants above enumerated there are examples of 

 this plant from : SOUTH AMERICA : Spruce, n. 6541 ' PI. Exsic. -ZEquatore- 

 ales, Chanduy, in litore Maris Pacific! ' ; Paraguay : coll. by Thos. Morong 

 1888-90, n. 978 (named G. maritimum, var. polycarpum, Tod) ; Bolivia : 

 coll. by Britton and Eusby in 1890, n. 647 (Yunyas), and by the same in 

 1891, n. 1201 (Cochabamba) ; Socotra : by Dr. Bayley Balfour (B.C. 5) 

 collected in 1888; and on Garieh Plain, collected during Ogilvie-Grant- 

 Forbes Exped. 1899 ; WEST INDIES : certain specimens of a plant collected 

 by Dr. Parnell in 1840 at Montego Bay, Jamaica. These match very closely 

 Seemann's n. 32, and are therefore in all probability examples of a remark- 

 able hybrid between G. peruvia/num and G. vitifolium. In shape of leaf, 

 pilose surface and small sharply toothed bracteoles, they closely resemble 

 the latter, but in seed, fuzz and floss, they come very near to the former. 

 I should not be surprised were Seemann's specimens, and the present set, 

 viewed in the future as exemplifying a form sufficiently distinct to justify 

 separate recognition. Lastly there is in Edinburgh a plant collected by 

 Mr. G. F. Scott Elliot, n. 2103, in Madagascar, which I have some difficulty 

 in determining. It looks as if it might be a cross between G. ptvnctatvm 

 and G. peruvianum. 



In the Cambridge Herbarium : A duplicate of Spruce's n. 6541. In the 

 Calcutta Herbarium there is a specimen collected in Madras, and which has 

 been named G. arboreum and recorded under Wallich's n. 1875. In the 

 Herbarium E.E.P. Calcutta : A sample of Egyptian cotton grown at Sibpur ;
