Abstract

A FLOR1STIC INVENTORY OF THE LOMA MOUNTAINS IN SIERRA LEONE

Our surveys in Sierra Leone of the flora of the Loma Mountains and the foothill country have enabled us to produce an inventory of the I 576 species, subspecies or varieties of Angiosperms belonging to 757 genera and 135 families. Gymnosperms are lacking.

As in any other natural region, the Loma flora is the result of a long and complex process which took place in much earlier times. Under the influence of climatic factors, migration, speciation and also anthropological action, floristic elements with very different origins have ultimately arranged themselves into a particularly diversified but unstable mosaic and it is for us to unravel the mechanisms that have brought this about.
