SOME GENERA AND SPECIES NEW TO THE 
PHILIPPINE FLORA. 
By Elmer D. Merrill. 
(From the botanical section, Biological Laboratory, Bureau of Science, 
Manila, P. I.) 
In recently published papers on Philippine botany many genera and 
species have been recorded from the Philippines that were previously not 
known to occur in the Archipelago, one of the striking proofs of the 
present comparatively limited knowledge that we have of the flora of the 
Philippines. As collections of botanical material are made in various 
islands of the group, genera and species previously known from sur- 
rounding regions are constantly being found, and a few of these, mostly 
observed in recently collected material, are recorded in the following- 
paper. 
ALISMACEiE. 
SAGITTARI A Linn. 
Sagittaria sagittifolia Linn. Sp. PI. (1753) 993; Buclienau in Engler’s 
Pflanzenreich 16 (1903) 46. S. sagittcefolia var. diversifolia Miclieli in DC. 
Monog. Phan. 3 (1881) 66. 
Mindanao, Lake Lanao, Camp Keithley (888 Mrs. Clemens) November, 1906. 
Europe and Asia, extending to Hainan, Formosa, Japan and Java. 
This widely distributed species has previously been known as a Philippine 
plant only by the doubtful record given by Naves, 1 who states that he saw living 
specimens in the Island of Panay, and dried specimens in Vidal’s herbarium, 
although Vidal does not record the species in any of his published works on the 
Philippine flora. 
GRAMINEyE. 
Phalaris minor Retz. Obs. 3:8; Hook. f. FI. Brit. Ind. 7 (1897) 221. 
Luzon, Province of Benguet, near Baguio (Major E. A. Mearns ) April, 1907, 
probably introduced. 
Southern Europe to British India, South Africa and Australia.
