Williamsia sablanensis (Elmer) ^Merrill comb. nov. 



TJrophyllum sahlanense Elmer Leafl. Philip. Bot. 1 (1006) 39. 



Luzon, Province of Benguet, Sablan, Elmer 6131, April, 1904 (type) ; Baguio, 

 Elmer 8551, March, 1907; M'iUiams 1028, October, 1904. Mixdaxag, District of 

 Zamboanga, Copela^id 16^2, Eebruary, 1905; Sax River, Williams 2336, February 

 15, 1905: Lake Lanao, Camp Keithley, Mrs. Clemeiis 531. May, 1905, and without 

 number, July, 1907. 



This new genus is manifestly allied to TJrophyllum, 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, 190.3, to July, 1905.
