Luzon, Rizal Province, Pasay, Mrs. Geo. H. Fairchild’s gar¬ 
dens, Bur. Sci. 79663 Quisumbing, August 22, 1930. The living 
plants were originally collected by Mr. Emilio Ermitano, an 
orchid grower and dealer of Manila, from the grasslands below 
the Canon Road, Baguio, Mountain Province, in February, 1929, 
and sold to Mr. W. Parsons, who has the plants now in his 
gardens at Geneva, Switzerland. The same variety was again 
collected by Mr. Ermitano from about the same locality, in 
February, 1930, and sold to Mrs. Geo. H. Fairchild. 
The new variety appears to be a natural hybrid between the 
light purple Spathoglottis plicata Blume and the yellow Spatho¬ 
glottis vanoverberghii Ames. The floral structure and form re¬ 
semble those of S. plicata Bl. The pubescence of the peduncles, 
pedicels, and outer surface of the sepals, however, is a feature 
of S. vanoverberghii Ames. The variety is readily distinguished 
from the two species by the color of the flowers. This variety is 
named in honor of Mr. W. Parsons, who, during his residence in 
Manila, courteously placed the facilities of his orchid collection 
at the disposal of the junior author. Mr. Parsons, at his home 
in Genthod, near Geneva, has now the best and largest collection 
of Philippine orchids in Switzerland.
