lanceolate, broadly obtuse, 1-nerved, about 3.75 mm long, 1.25 mm 
wide. Labellum attached to the foot of the column, spurred, 
3-lobed; lateral lobes erect, petaloid, linear, slightly curved, ob¬ 
tuse, about 2.75 mm long, 0.75 mm wide; middle lobe a short 
fleshy, conical, papillose tooth; spur cylindric-conic, dorsoven- 
trally flattened, about 4 mm long, 2 mm wide, the tip broadly 
rounded or subtruncate. A pair of minute uncinate lobules 
stand inside the base of the lateral lobes. Gynostemium very

Luzon, Benguet Subprovince, Baguio, gardens of the Mansion 
House, Bur. Sci. 82203 Quisumbing, May 6, 1931. The living 
plants were originally from the mountains near Baguio, but the 
exact locality is unknown. At present the living plants are 
growing in the Bureau of Science orchid house. Sepals and 
petals white dotted with purple-red; labellum white except the 
inner surfaces of the lateral lobes which are dotted with purple- 
red ; anther yellow; back side of the column carmine; pedicellate 
ovary marguerite yellow. 
Among the Philippine species, this plant appears to be allied 
to Sarcochilus palawanensis Ames but differs strikingly in its 
short racemes and in the dissimilar form of the perianth seg¬ 
ments.
