(Received on March 15，2 006)
The taxonomy of Anemone L. species distributed in the Southem Hemisphere was
re-evaluated on the basis of ac ritical morphological analysis of the available herbarium
material. A conspectus，ke y，de tailed morphological descriptions，to gether with figures of
flowers and fruits，a nd critical notes on all taxa are presented. Wea ccept 21 Anemone
species representing nine sections，a nd we confirm the validity of A. triternatα，A .
fanninii and A. peruviana which were not accepted by other authors. Wei nterpret the
mo叩hologicalsimilarities between A. thomsonii，A . caffra and A. janninii，A .
