The typical plant of Java has very much larger leaves than our form. 
A very narrow lanceolate-leaved plant, invariably male, and growing in the 
same locality as caninum, I have always believed to be a male form of it. 
It is the var. angustifolium of Miquel and Hooker of caninum, and a variety 
of bcehmeyicsfolium, an erect Chavica, of C. DeCandolle. It was abundant 
in the Garden jungle.
