The area incliided for Lhe plants, wliich are enumerated in this paper, 

 is lhe area comprised within lhe présent political limits of lhe colony of 

 lhe Gambia, as finally setlled in lhe Anglo-French Agreement daled Oc- 

 tober 1905. The ratification of this Agreement was the delinite seulement 

 of an arrangement, signed at Paris on 10 August 1889, concerning the 

 délimitation of the English and French Possessions on the West Coast of 

 Africa, and establishing lhe fronlier line separating lhe colony of the 

 Gambia from Senegal on the north and French Guinea on the south. At 

 the easlern end of the colony, by the instrument of October 1905, the 

 enclave of Yarbutenda, near lhe head of navigation, is ceded to French 

 Guinea, so as to give France acceds to lhe head-waters and to the navi- 

 gable course of the river Gambia. North and south of the river, the fron- 

 lier, formerly vaguely deflned, is clearly marked out, and somewhal modi- 

 fied from the previously assumed uncerlam boundaries. These final 

 modifications in the settlement of lhe fronlier line are carefully lakeninlo 

 account in the préparation of Ulis list of plants. Their inclusion in or 

 omission from this part of West Africa bears a strict référence to the 

 aulhenlic map of lhe colony in the Officiai Handbook for the Gambia 

 Colony and l'rotedorate, by Mr. F. Bisset Archer, of the Colonial Service, 

 recenlly published (May 19Ü6). This bas to be borne in mind, as the most 

 useful of the few collections of planls from lhe Gambia was made during 

 lhe journey of lhe Gambia Delimilalion Commission of 1890—91, which 

 kept lo lhe neighbourhood of the alleged frontier. Only those planls from 

 lhe collection which were gathered in localilies which proved aflerwards 

 lo be in British territory, are included in the présent list: lhe olhers are 

 slriclly exciuded.
