Luzon, Manila, Bureau of Science orchid house, Phil. Nat. 
Herb. 104 Quisumbing, February 28, 1933. The living plants 
were originally gathered by Novaliches orchid peddlers from 
the mountains of Rizal Province, Luzori, back of the town of 
Antipolo. The plants are now being cultivated in the Bureau 
of Science orchid house and in the gardens of Mrs. Remedios C. 
Gonzales. The description was based on Bureau of Science ma¬ 
terial which flowered in Manila February 28, 1933. The flowers 
are fairly large and odorless, and remain fresh for three to 
four days. Pedicellate ovary apple green; sepals straw yellow; 
petals and labellum chalcedony yellow; spur straw yellow with 
shades of ecru-olive and some very pale purple, light lumiere 
green at the tip. 
In the herbarium of the senior author is a colored sketch of 
this species from the Reichenbachian collection in Vienna. 
Thanks to this authentic record, one more obscure species is 
now shown to be represented by a recent definite collection. 
Apparently the original collection was destitute of leaves. It 
was described (and shown) as having light rose or reddish 
pedicellate ovaries whereas the recent collection has the pedi¬ 
cellate ovary apple green. 
A species closely allied to Dendrobium Guerreroi Ames and 
Quis. but differing from it in its fusiform, short, angled stems, 
in its few-flowered racemes, in the color of the flowers, in the
