Poa LUZONIENSIS, Merrill, in Philipp. Journ. Sc. i. Suppl. (1906) 180. 
Distrib. Utakwa Valley, with no precise locality. 
Identical with a plant from the mountains of Java [at Nyadasar at 2000 metres 
(Koorders) and probably Tosari (Hullett)]. I have seen no Philippine specimens, but 
the description by Merrill suits this plant. :
