 free, shorter than the antbers or scarcely exceeding them. Anthers termi-

The genus, as at present constituted, is dispersed over the tropical regions of the ^e^^ 

 well as the Old World, with one species extending to the East Mediterranean region. 

 Anstrahau species are, however, as far as hitherto ascertained, all endemic. 



Flowers small ia compound cymes. Corolla rotate. Leaves 

 broad or narrow, not cordate.
