On the Vegetation of Clarence Peak, Fernando Po; with De- 
scriptions of the Plants collected by Mr. Gustav Mann on 
the higher parts of that Mountain. By J. D. Hodker, Esq.,

[Read March 7th, 1861.] 
A KNOWLEDGE of the temperate flora of any spot on the west 
coast of Tropical Africa has long been one of the greatest deside- 
rata in botanical geography, not only on account of the intrinsic 
interest that must attach to the plants of the extremely few 
isolated points so elevated as to possess a temperate climate in 
that vast humid and torrid area, but also from the light such 
plants might be expected to throw on the floras of St. Helena, 
the Cape de Verd, and the Canaries; all of which (and especially 
the former) contain peculiar endemic genera, whose nearest allies 
might be expected to exist on the mountains of the neighbouring 
continent. 
Within the last year the outlines of such a desiderated flora 
have been supplied by the energy and resolution of Mr. Gustav 
Mann, of the Royal Gardens, Kew, who was appointed by Lord 
John Russell (Foreign Minister) to succeed the late lamented 
Barter, as botanist to Dr. Baikie's Niger Expedition, but who, 
being unable to ascend the river and join that expedition, has 
devoted a year and a half to exploring the island of Fernando Po, 
and has twice reached its lofty summits, 10,700 feet above the sea ; 
on both occasions collecting indefatigably and preserving his 
collections well.
