 Eayangos, from seed obtained from Khartoum) ; E. AFRICA : Abyssinia, ex 

 herb. Tranqueville, n. 266 ; Lower Shire Valley, Sir John Kirk (speaks of 

 a cultivated perennial shrub, which appears to be a hybrid of this plant) ;

In the British Museum Herbarium there are many examples of great 

 interest. In the Sloane Herb. (Beaufort collections, vol. 132, f. 18) there are 

 leaves said to have come from Barbados (? seeds grown at Badminton) ; 

 specimen in Clifford's Herb, (named ' G. arboreum 8 '). INDIA : Wight, 

 n. 180 ; Heifer's Bengal specimen, n. 44 ; JAVA : Horsfield Herb. ; AFRICA : 

 Welwitsch, nn. 5,235 and ? 5,222 ; MADAGASCAR : Boivin, 1854 ; AMERICA : 

 Mexico, Palmer, n. 10 (1886). In the Cambridge University Herbarium the 

 following may be specially mentioned: Friendly Islands (Tonga) coll. by 

 Mathews, nn. 149 and 150 ; Ind. Or. Wight Herb., n. 180 (ex herb. Henslow). 

 In the Edinburgh Herbarium : a specimen named G. indicum, Griechen- 

 land (a form that looks almost as if it were a hybrid of G. hirsutum and 

 G. herbaceum). In the Herbarium, Eoyal Botanic Gardens, Calcutta, there 

 is a long series of specimens that fall into this position of which mention 

 may be made, Wight, n. 218 ; G. Thomson, collected near Madras, 1845 ; 

 a specimen from Tahiti. In M. de Candolle's Herbarium, Geneva, collected 

 by P. Levy in Nicaragua in 1870 (n. 381), hi which the bracteoles are very 

 small and more ovate acute than is ordinarily the case. From the United 

 States of America, Herbarium of Plant Industry, Department of Agriculture, 

 a long series has been most obligingly sent me for inspection. The more 

 interesting will be discussed in a further paragraph (see pp. 231-9). In the 

 Herbarium of E.E.P., Calcutta, there are specimens collected by me at 

 Mangrol, also in Bhavnagar, during explorations conducted in 1894. In 

 Ahmedabad it was found wild in a hedge around a garden (n. 1742). 



In every one of the above the indication is given of its being a cultivated 

 plant, or one which has escaped from recent cultivation. In some respects 

 this species recalls the JceJcchi cotton of Guatemala described by Co jk, except 

 that the glands do not seem to be ordinarily protected with the structures he 

 names as bractlets. 



Affinities Nomenclature. The nearest affinities of the Mexican cotton are 



of Mexican doubtless G. hirsutum, on the one hand, and G. purpurascens on the 

 other, but it is quite distinct from either. Eoxburgh (' Hort. Beng.' 

 pub. 1814) alludes to it as introduced into India by W. Hamilton 

 in 1804 ; but subsequently he seems to have confused it with Bourbon 

 cotton (G. purpurascens), and gave both plants the botanical name 

 of G. barbadense, Willd., (see ' Fl. Ind., in., p. 187). He further 

 alludes to Mexican cotton apparently, under G. hirsutum (grey 

 seeded), while curiously enough his two MS. illustrations (nn. 425
