overlooked the fact that, of the Ihree specific homonyms iinder the name 

 of C. triloba, the earliest in point of date is that of Thunberg, so that this 

 is the name which has to be used in rediicing the plant to a variety of 

 C. Orientalis. Thomson's Indian spécimens are those of a more mobile 

 plant with narrower leaves (in spite of its name of latifolia).

127. Argemone mexicana L. — Gunjour in S. Kommbo district; 

 grows near moist ground, such as the village well (Lester, n. 1 S). Common 

 almost everywhere in the Tropics as an introduced weed (Bowdich). Gol. 

 D. Prain says (Journ. Bot. 1895, p. 326) in his monographie revision of 

 Ihe genus Argemone, that it is rather unfortunate that Bauhin's specific 

 epithet was not taken up by Tournefort or by Linnaeus, because the one 

 by which it is known is somewhat of a misnomer. The plant came to 

 Gerard from the Antilles group, not from Mexico; except as a plant, al- 

 most certainly introduced, from the vicinity of one or two of the ports on 

 the east coast of Mexico, the species is unknown from Mexico in European 

 herbaria. By the Mandingos of the Gambia an infusion of the leaves is 

 used for coughs.

129. Capparis polymorpha Guill. et Perr. Fl. Senegamb. Tent. 

 24, t. 5 (1831). — In woods of the Gambia opposite the Senegambian 

 province of M'Boro. In FTA. is reduced by Oliver to C. tomentosa Lamk. ; 

 from West African spécimens of which, however, it seems sufficiently 

 distinct (Heudelot, n. 370). Vallot (Etudes fl. Sénégal, 1882, p. 77) also 

 keeps C. polymorpha separate. A spécimen of « C.puberulay collecled by 

 Don also seems to belong here. Brass's type-specimen of the latter is in 

 herb. Banks. 



130. Boscia angustifolia Guill. et Perr. Fl, Senegamb. Tent. 26, 

 t. 6. — Dog Island, in Lower Niumi district. The Gambian plant here 

 figured (for which I propose the name of var. alternifolia) represenls only 

 the less fréquent form with alternale leaves. The more common form,
