Description We examined the floristic composition and its relationship with environmental
factors across 80 floristic relevés of Piliostigma stands distributed along a north-south gradient
in Burkina Faso. Various diversity indices were computed. Detrended Correspondence Analysis
and Canonical Correspondence Analysis (CCA) were used to explore the relationship between
species occurring in Piliostigma stands and environmental variables. The results showed that
Piliostigma communities show only limited variation in species composition among sites. The
first two axes of the DCA together explained 16.5 % of the floristic variation. The CCA showed
that climatic variables explain 42 % of the species variance. The Piliostigma reticulatum
asssociation is adapted to reduced rainfall and sandy soil, whereas the P. thonningii association
occurs preferentially on clay soil.
