F. N. WILLIAMS. FLORULA GAMBIGA. ÖO 



doubt has been given to too many. The majoriLy, consistiiig of 142 names 

 of planls, are disposed of as follows. There are 3cryptogams; 29 are those 

 wliich have certainly been inlroduced more or less ibr cultiva lion, 50 are 

 referred only lo the genus, and 60 names (tlial complète the 142) are most 

 probably errors, many of them only two obvious. It may be of inlerest to 

 give Ihese 60 planls: — Commelina erecta, Poiygonum bistorta, Cheno- 

 podium multifldum, Amaranthus angustifoliiis, Riiellia alopeciiroides, 

 Nepela multiciliata, Mentha citrata, Solanum furiosum, Crescentia Cujete,

 LoranlhusSenegalensis, Sonchus crassifolius, Carduus benediclus, Chryso- 

 coma {Ihree species), Senecio nemorensis, Cotula umbellata, Calendula 

 pluvialis, Pavonia arislata, Clematis chinensis, C. glauca, Cleome triphylla, 

 Hibiscus trionum, Hibiscus vesicarius, Sida muricata, Melrosideros um- 

 bellata, Psidium pyriformis. Phaseolus lathyroides, Hedysarum nummu- 

 larifolia, Inga fraxinea. I. unguis-cali, Cassia acuminala, Moringa arabica, 

 Indigofeia (three species), Robinia flava, Erylhrina picta, Glycine apios, 

 Medicago falcata. Favolus glaber, Mimosa Nilolica, Securidaca erecla, 

 Elseodendron argam, Rhamnus cassinoides, Samara floribunda, Cucurbita

Florx Seneqambiae Tentamen (1831 — 1833J, by Guillemin, Perrotted et 

 Richard. — The first volume only of this ambitions and excellent work 

 was published, with beauliful plates, It includes the Senegambian plants 

 fiom Ranunculacese to Myrtacese inclusive {i. e. to the 79th order in De 

 Candolle's Prodromus). Unfortuna lely the work was never resumed. Several 

 Oambiaii plants are enumerated, chiefly in the neighbourhood of Albreda 

 (al that time an enclave in British territory owned by France as a detached 

 portion of Senegal), collected byLeprieurin 1827 and by Perrottet in 1829. 

 Leprieur's plants are not numbered, but of Perroltet's some are and some 

 not. Some of the species herein described are reduced (in many instances 

 somewhat arbiti'arily) in the lirst two volumes of FL of Trop. Aftica. 

 The name of « Senegambia >> has always been a loose geographical ex- 

 pression, and has been applied to an area of West Tropical Africa varying 

 with the blas of the carlographer. It is now best abandoned, the more 

 especially now that Senegal and French Guinea are distinct colonies, ad- 

 ministralively severed in 1893, and their boundaries clearly defined in 

 1899. The title-page of this volume is dated 1830—1833; but the earlier 

 part was issued in 1831, and ihe later portion in 1833 (fide W. P. 

 Hiern). 



Niger Flora (1849), ediled by Hooker. The second portion of this work, 

 under the title of «Flora Nigritiana », by Bentham and Hooker fil., enume- 

 rates several of the Gambian plants collected by G. Don 27 years before, 

 and a few by Capt. Boteler. They are, however, usually mentioned in- 

 cidentally, and not asconstituents of the Flora of the territory. 



Flora of Tropical Africa (1868 — 1906, and not yet complète). This 

 important work occasionally cites species as from Gambia, but usually 

 includes the coiony in the comprehensive expression of « Senegambia » ; 

 so tbat it is not often possible, in the Flora per se, to sifl out the species 

 which have been recorded as found in Gambia. In the following list, 

 therefore, this extensive Flora is only cited in the case of those species in 

 which the actual name of «Gambia » is quoted as one of the specific areas 

 (distinct from Senegambia) in which the plant is recorded to have been 

 found. Cited throughoul in the abbreviated form of « F T A ».
