spur white with shades of mallow pink or phlox purple, the 
anther cap marguerite yellow and the base of the labellum pri- 
muline yellow. 
Luzon, Rizal Province, Pasay, Mrs. Geo. H. Fairchild’s gar¬ 
dens, Bur. Sci. 80820 Quisumbing, October 2, 1930. The 
plants were originally collected near Kilometer 42, Mountain 
Road to Bontoc, Mountain Province, growing on exposed rocks 
and they are now under cultivation in Mrs. Fairchild’s gardens. 
This species belongs in the group with De'ndrobium ramosii 
Ames, D. o’brienianum Kranzl., and D. epidendropsis Kranzl. 
It is especially close to the first, but differs radically in being 
a much larger plant with very much larger flowers with dis¬ 
similar floral details. 
The species is dedicated to Mrs. Geo. H. Fairchild, an orchid 
enthusiast with large collections in her gardens at Pasay, near 
Manila, and in Baguio. Through her untiring interest in Phil¬ 
ippine orchids, she has succeeded in cultivating many of the 
beautiful, rare, and wild orchids of these Islands.
