The arrangement followed in the présent List is Ihat of Engler and 

 Pranll, wilh the species placed alphabetically under each genus; with the 

 slight modification that the Orders are grouped into the higher grade of 

 Séries, — a principle in systematic taxonomy first introduced byWarming 

 of Kopenhagen, and endorsed by Goebel, and afterwards by Pfitzer. 

 « Orders » as hère understood, as also by Warming and Goebel, are équi- 

 valent to the « séries », of Engler and Prantl, the « cohorls » of Bentham 

 and Hooker, and the « alliances » of Lindley. Engler, in his Syllabus. fol- 

 lowing Eichler, does not recognize the terni of « orders » at ail, nor does 

 he recognize the necessity of defining any intermediate grade between 

 the subclass and the séries, but groups his families (équivalent to the 

 « orders » of the older systematists) into séries under each subclass. 



In the following enumeration only Ihose species are described a tiength 

 which hâve not hitherto been l'ound beyond the présent political limils of 

 the Colony of Gambia, though this is not going so far as to say that such 

 plants are endémie in Gambia. Furlher investigation of the Flora of ad- 

 joining countries, and assiduous sifting and sorting of the accumulaled 

 matehal of future collectors, will probably reduce iiiany such claims, and 

 and will not add many olhers. At the end of the paper a list of such plants 

 will be given. This will be followed by a list of the new names or new 

 combinations, which adjustment of the synonymy or the exigencies of the 

 Berlin Recommendation s require. 



Références are only given in the case of new names published after 

 30 December 1885. Ihe terminal date of the names which areincluded in 

 the Index Kewensis : or where the authorities or citations are différent 

 from Ihose quoted in the Index Kewensis, or otherwise inaccurate.
