DOUBTFUL AND EXCLUDED SPECIES 



Cyperus albus Presl Rel. Haenk. 1 (1828) 175; Miq. Fl. Ind. Bat. 3 



(1856)-287; Steud. Syn. PI. Glum. 2 (1855) 52; Naves Novis. App. 



(1882) 306; C. B. Clarke in Philip. Journ. Sci. 2 (1907) Bot. 81. 

 "Hab. in insula Luzon" Presl. This is a Pycreus judging from Presl's 

 description of the styles as 2-fid. It is necessary to examine the type to 

 determine its status. 

 Cyperus luzonensis Presl Rel. Haenk. 1 (1828) 174; Steud. Syn. PI. Glum. 



2 (1855) 52; Miq. FL Ind. Bat. 3 (1856) 287; Naves Novis. App. 



(1882) 306; C. B. Clarke in Philip. Journ. Sci. 2 (1907) Bot. 81. 

 "Hab. in insula Luzon" Presl. The type should be examined as the 

 status of the species is hardly determinable from the description alone.
