This is the African representative of the Persian and 
Caucasian Hpimedium pinnatum, tab. 4456, from which it 
is distinguished by its leaves being invariably only tri-folio- 
late, and by its much more strongly ciliate-toothed leaflets, 
which are perennial, and when young of a beautiful bronze- 
colour shot with green. In the form and colouring of the 
sepals and petals these two species are so alike that they can 
hardly be ranked higher than geographical forms, and it is 
far from improbable that specimens connecting them will be 
found in Southern Europe, if not in Africa. The texture of 
the leaves is so firm that even in this climate they persist 
during the winter. ce 
Epimedium Perralderianum is a native of the moun- 
tain-woods of Babor, Foughell and Tababor in Hastern 
Khabylie, at elevations of 3000 to 5000 feet, whence it was 
introduced into cultivation by Dr. Cosson. The plants 
from which our figure is taken are perfectly hardy in Kew, 
and were presented by Dr. Reichenbach.
