Type specimen number 16168, A. D. E. Elmer, Irosin 

 (Mt. Bulusan), Province of Sorsogon, Luzon, May, 1916. 



This remarkable plant was discovered at the upper 

 edge of a high water fall, lodged upon the very end of 

 the overhanging bed rocks of a very humid densely wood- 

 ed gulch at 2000 feet altitude. It was the only plant I have 

 seen during my six months exploration in this region. 



It belongs to the sectiou of Eubractea and is the 

 first Alpinia in this section reported from the Philippine 

 Islands.
