In recent!}' published papers on Pliilippine 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. 



ALISMACE.E. 



SAGITTARIA Unn. 



Sagittaria sagittifolia Linn. Sp. PL (1753) 993; Buchenau in Engler's 

 Pflanzenreich 16 (1903) 46. 8. sagitttefolia var. diversifolia Micheli in DC. 

 Monog. Phan. 3 (1881) 66. 



Mindanao, Lake Lanao, Camp Keithley (888 Mrs. Clemens) November, 1900. 



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 Jiaves,'^ who states that he saw living 

 .specimens in the Island of Panay, and dried specimens in Vidal's herbarium, 

 although Tidal does not record the species in any of his published works on tlie 

 Pliilippine flora.

Phalaris minor Ketz. Obs. 3:8; Hook. f. Fl. Brit. Ind. 7 (1897) 221.
