Caperonia. | CXXIL. EUPHORBIACE® (PRAIN). 83] 
Dusén’s Cameroon specimen has the leaves rather distinctly punetate above, but. 
does not otherwise differ from MOller’s St. Thomas’s Island plant. This. very distinet 
species, though first described from African wuterial, appears to be an introduction 
from America, where it is wide-spread (West Indies, Hd. Forsyth: Panama, Sutton 
Hayes 703; Brazil, Trail 743; Peru, Tweedie) , and has hitherto been confused now 
with C. palustris, now with C. castaneafolia. It is the only Caperonia, besides 
C. cordata, St. Hil., with the leaves palmately nerved at the base.

This Species is most nearly allied to C. palustris, and is only distinguishable by 
the colour of its seeds. We have not seen the specimens colleeted by Stuhhnann 
at Quillimane,
