HORNSTEDTIA Retz.

Represented by number 17176, Elmer, Irosin (Mt. Bu 

 lusan), Province of Sorsogon. Luzon, September, 1916. 



Hornstedtia pubescens (Ridl.) Elm. n. comb. Amomum 

 lepicarpa pubeacens Ridi. in Leaf. Philip. Bot. II, 604, 1909. 



In my opinion it quite deserves specific rank by 

 reason of its being a much larger plant, coupled with 

 numerous other specific characters. The flower and fruit 

 belongs to Hornstedtia rather than to Amomum.
