tusa, 5.5 ad 7 mm longa, 2.9 ad 3.5 mm lata, 1-nervia. Labellum

cm in diameter, conspicuously many-ridged with rounded angles. 
Leaves distichous, linear, obtuse, 4 to 7 cm long, 3 to 4 mm wide. 
Racemes short; the flowers appearing singly, about 1.4 cm 
across. Lateral sepals broadly triangular, subacute, 6.5 to 8 
mm long, about 15.6 mm broad along the column-foot, 6- to 
7-nerved. Dorsal sepal oblong-ovate, subacute, 6 to 7 mm long, 
about 3.5 mm wide, 5- to 7-nerved. Petals oblong-elliptic, ob¬ 
tuse, 5.5 to 7 mm long, 2.9 to 3.5 mm wide, 1-nerved. Spur or 
mentum conical with elongated apex. Labellum simple, cuneate- 
obovate, crenulate on the anterior margins, 15.7 to 18 mm long,

Luzon, Manila, Bureau of Science orchid house, Bur. Sci. 
85617 E. Quisumbing, December 14, 1932. Living specimens 
were presented to the junior author by Mr. L. H. Phillips, 
formerly of Bukidnon, Mindanao, who collected them from the 
hills of Bukidnon. The plants have flowered several times in 
the Bureau of Science orchid house during the months of July, 
August, and December. The flowers are not fugacious (re¬ 
maining fresh for two days) and are slightly fragrant. The 
sepals are marguerite yellow. The petals almost white with a 
slight tinge of primrose yellow at the tips, and the spur slightly 
cream-colored; the ridge at the middle of the labellum apricot 
yellow. 
This species is allied to Dendrobium gracile (Bl.) Lindl., but 
differs in not having subulate leaves, in its oblong-ovate dorsal 
sepal, and in the color of the flowers.
