INTRODUCTION. 



By I. H. Burkill, M.A., F.L.S. 



I N the autumn of 1894 Messrs. F. V. McConnell and J. J. Quelch first visited Roraima ; 

 they were there again in the autumn of 1898, and on hoth occasions not only encamped 

 higher on the slopes of the mountain than any previous traveller, but they spent nights 

 on the summit in order that the time given to collecting its flora and fauna should be 

 uninterrupted. The collections of plants were transmitted to Kew, and hoth are 

 enumerated in this paper.
