﻿TROPICAL AFRICAN SCREW PINES. 

 By A. B. Rendle, M.A., F.L.S. 

 (Plate 847.) 



In the notes appended I have tried to bring together the material 

 preserved at the British Museum and at Kew, and to discover how 

 many species of Pandanus from Tropical Africa are therein repre- 

 sented. In this attempt, Prof. Balfour's list in the Linnean Society's 

 Journal (Botany, xvii. 33-68) has been of great service, and it is 

 matter of much regret that the monograph of which it was to have 

 ^een the forerunner is still a desideratum. Some species I have 

 ventured to describe merely from the fruit, thinking it better, 

 where these were obviously representatives of new species, to give 

 them a name rather than to relegate them to indeterminatse. For 

 facilities in examining several of the fruits in the Kew Museum 

 I am indebted to the courtesy of the Director of the Royal Gardens. 



As the species seem to keep fairly to the coast line, in our pre- 

 sent knowledge, I have kept the East and West tropical ones 

 distinct. The uncertainty about P. Candelabrum Beauv. is a 

 deterrent to the description of nearly allied West tropical forms ; 

 I have, however, come as nearly as is, I think, at present possible 

 to the elucidation of Beauvois' species.
