F&m. ^^. BORRAGINACEM 



220. Heliotropium indicum L. — Gunjour in South Kommbo 

 district (Lester, n. 4 S). Local name « Cock's comb ». An infusion is used 

 in venereal disease among the Mandingos. 



Fam. 56. SOLANACEyE 



221. Physalis angulata L. — St. Mary's Island (Bowdich). Niumi 

 district (Lester). Native name « Gubum Pap ». Used as an external counler- 

 irritaiit, like mustard. 



222. Capsicum frutescens L. — St. Mary's Island (Bowdich). 



223. Solanum aculeastrum Dunal. — SL Mary's Island (Bow- 

 dich, as « 5. Sodomœum »). 



224. Solanum aethiopicum E. Torner, Cent. Plant. II. 10, n. 126 

 (.lun. 1756). et reimpr. in Amœnit. Academ. IV. 307 (Nov. 1759). — 

 St. Mary's Island (Bowdich). 



225. Solanum aggregatum Jacq. (1790). — St. Mary's Island 

 (Bowdich, as « S. nodiflorum «). This is the plant probably intended by 

 Bowdich, as it is identical with Solanum nigrum var. Guineënse L., which 

 is found both in Sierra Leone and in the Senegambian province of Futa- 

 Jallon. 



226. Solanum Carolinense L. — St. Mary's Island (Bowdich). The 

 leaves are bruised, boiled, and applied externally for Grawcraw, a kind 

 of itch. Possibly introduced from North America. 



227. Solanum diplosinuatum Klotzsch. — Shrubs 3-4 feet 

 high, growing about Gunjour in South Kommbo district (Lester, n. 3 S). 

 FT A. IV. sect. 2. 244. 



Other species of Solanum are also given by Bowdich as growing in 

 St. Mary's Island, in the neighbourhood of Bathurst; but they are not 

 identifiable except in so far as they are obvions introductions. 



Fam. 57. APOCYNACE^ 



228. Landolphia Heudelotii Gand. 2"«. — FT A. IV. sect. 1. 55. 

 Kommbo district (Heudelot). Lower Niumi district, on dry sandy soil near 

 Albreda. and very common along the R. Gambia (Perrottel, n. 491). Ori- 

 ginally described from almost glabrous spécimens; such seem, however, 

 to occur rarely, the tomentose form being the the common one. This 

 species is, among Apocynacex, undoubtedly one of the most valuable 

 sources of rubber in West-Africa.
