258 WILD AND CULTIVATED COTTONS 



matches exactly the next sample. INDIA: (a solitary specimen Cult. 

 Saharanpur, Dr. Falconer, n. 286). MALAYA : Cambodia, Pierre, n. 1,043. 

 AFRICA : Source of the Nile, Speke and Grant (said to be found near ruins of 

 a deserted village, 1860-63) ; Egypt, many (described as G. barbadense) ; 

 Senegal, (ex. herb. J. Gay spoken of as ' Cotonier de Georgie ') ; Gold 

 Coast, specimen recently contributed by Mr. Dudgeon under the name 

 ' Kidney cotton of Sittam, E. Akim, Ashantee,' and a second sample spoken of 

 as native black-seeded cotton of Labolabo. MADAGASCAR : (ex Herb. Paris) 

 collected Voy. M. de Boivin, 1847-52 (shoots long-angled, often with solitary 

 peduncles at each joint and thrown to one side). WEST INDIES : no examples. 

 AMERICA : Argentine (Tucuman), collected by Tweedie in 1837 ' grows 

 plentifully but cotton of little use.' 



In the Linnean Herbarium there is a leaf and flower shown by me on 

 Plate No. 49A which may be this species : it appears to have come from 

 Surinam. 



In the British Museum Herbarium there are in many respects the 

 most interesting specimens of this species to be seen anywhere. In the 

 Sloane section there is a fairly long series, but mostly in the form of leaves 

 only, such as Plukenet's set, vol. 84, f. 87 (leaf almost entire) also 85, f. 146 ; 

 (Beaufort set) vol. 132, f. 18, two specimens, one the present species, the 

 other G. ? mexicanum, said to be from Barbados ; (Petiver's set) vol. 159, 

 f. 205, a fragmentary specimen furnished by Dr. J. Marshall from ? Virginia 

 mentioned in Petiver's list, the preface of which is dated 1698 ; lastly (Boer- 

 haave's set), vol. 322, a specimen collected from his garden, source not 

 stated. In the general herbarium there is a specimen from Java by Horsfield ; 

 from Egypt a doubtful specimen by Schweinfurth, n. 186 ; from Ecuador by 

 Spruce (1857) ; Surinam by Berthoud-Coulon, n. 249 (possibly a new 

 species) ; and from Paraguay by Hassler, n. 7,578 (also possibly a new species). 



In the Calcutta Herbarium there are two sheets of this plant that match 

 Falconer's n. 286 very closely ; these bear as the record of their history 

 the letters H.B.C. but no date. A third sheet that may be a hybrid between 

 this species and G. mexicanum is named G. flavescens, but is dated Novem- 

 ber 16, 1807, and appears to have been obtained from Madras and has 

 been recorded under Wallich's n. 1,875. 



In M. de Candolle's Herbarium at Geneva there is a specimen from 

 Jamaica collected by Murray in 1827 ; several sheets from Egypt such as 

 n. 317, collected in 1834 and a somewhat doubtful specimen named ' Jumel 

 cotton ' ; specimen collected M. Boissier, cult. Maloga 1837 ; and a plant 

 named G. religiosum identified with Bohr's ' muselin ' cotton. 



Nomenclature. "While I have thus not discovered in any her- 

 barium specimens of this plant recorded as procured from Mexico 

 proper, as already stated I am disposed to think that Hernandez (Lc.) 

 may have intended to indicate it as the Ychcaxihuitl of the Mexicans. 

 His drawing manifests most of the more diagnostic conditions of 

 G. vitifoUum, though of course 250 years ago it is not likely that 

 the plant would have been recognised as different from G. brasiliense 

 or G. peruvianum. Hernandez speaks of this species as extremely
