Wenzel in Leyte, and by Weber, Reillo, Serrato, Lyon, and Disdan, 
the types are preserved in the Herbarium of the Bureau of 
Science at Manila, and the cotypes in my herbarium. The types

ADENOSTYLIS Blume 
1. ADENOSTYLIS ELMERI Ames in Elm. Leafl. Philip. Bot. 5 (1912) 
1552. 
This interesting species has been found again by Father M. Vanoverbergh 
in Bontoc Subprovince, Luzon. The type was collected in Baguio, Province 
of Benguet, in March, 1907, by A. D. E. Elmer, 5,000 feet above sea level. 
From A. marivelensis Ames this species is to be distinguished by its much 
smaller flowers.
