Mercurialis annua , Linn., is a species widely spread in the Mediterranean basin, 
whence it extends northwards to Central and Western Europe, and westward to 
Madeira and the Canaries. It appears to have been introduced to South Africa, as 
a weed, before the middle of the eighteenth century, but even yet it has not become 
very common or spread very far from the Cape Peninsula.
