Of this species, also, the collection contains only a poor specimen, 

 with male flowers. The leaves, about 3 inches long, and 2i inches 

 wide, are rounder, of a thicker and more coriaceous texture than those 

 of the preceding species, and quite entire. The male inflorescence and 

 flowers, however, are similar, except that the calyx is not so deeply 

 four-cleft, and its rounded lobes very obtuse.
