NEW OR NOTEWORTHY ORCHIDS 
at intervals of about 1 cm. Pseudobulbs 5 mm. long, 
obpyriform, about 3 mm. thick at the base, much wrinkled 
when dry, yellowish or greenish, monophyllous. Leaf 
1-2.5 cm. long, 4-7 mm. wide, elliptical or elliptic-lanceolate, 
rounded at the base and passing into a short petiole, acute, 
coriaceous. Petiole 2 mm. long, slender. Scapes up to 
4.5 cm. long, arising from the base of the pseudobulbs or 
from the rhizome between the pseudobulbs, liliform, weak, 
1-flowered.. Flowers dark purple when dry, described as 
being black by the collectors. Pedicel and ovary about 
2.5 mm. long, subtended by an abbreviated tubular bract. 
Lateral sepals 4.5-5 mm. long, about 1.5 mm. wide near the 
base, triangular-lanceolate, acuminate, acute, 3-nerved, the 
nerves closed. Dorsal sepal 5 mm. long, lanceolate, similar 
to the laterals, 3-nerved, minutely glandular on the upper 
surface near the tip. Petals about 3 mm. long, scarcely 
1 mm. wide below the middle, above the middle suddenly 
contracted into a caudate glandular termination, 1-nerved. 
Labellum 3-lobed, about 2 mm. long, 1 mm. wide across the 
expanded lateral lobes, obscurely cordate at the base; 
lateral lobes extending to about the middle of the labellum, 
rounded in front, erect or nearly so when in natural position, 
diaphanous, 1 mm. long; middle lobe about 1 mm. long, 
hardly .5 mm. wide, rather lleshy, copiously glandulose. 
Disc with a gnomon-like keel along the middle which extends 
from near the base of the labellum to about the centre of the 
mid-lobe. Column short, produced into a distinct foot, with 
a stelidium on each side in front at the summit. 
From Bulbophijllum peramoenum Ames, which is a 
closely allied species, B. glandulosum differs conspicuously in 
having dissimilar petals which are distinctly and profusely 
glandulose above the middle. From B. Toppingii Ames, an¬ 
other closely allied species, it is separable by its conspicuously 
glandular petals and labellum and in its dark purple flowers.
