Williamsia sablanensis (Elmer) Merrill comb. nov.

This new genus is manifestly allied to Urophyllum, but is at once distinguished 
from that genus by its sessile, axillary, solitary or fascicled flowers, and the 
presence at the base of the calyx of two cupular, imbricate, 4-toothed bracts, 
inclosing the base of the calyx, the lower one the smaller. It seems to be even 
more closely allied to Gonyanera Korth., but is readily distinguished from that 
genus by its more numerous ovary cells. Dedicated to Mr. R. S. Williams of 
the New York Botanical Garden, who made extensive botanical collections in the 
Philippines from October, 1903, to July, 1905.
