FLORA OF BRAZIL. 99 
The shrub on which I have established this genus, and 
heve named it in honour of Sir Walter Raleigh, the 
celebrated American voyager, has very much the habit of 
some species of Weinmannia; but in the structure of its 
flower and fruit it comes near to Prockia and Banara. It 
seems to be the only plant belonging to the Order which has 
opposite leaves.
