24 AMES. 
Lateral sepals triangular-lanceolate from a broad base, 7 mm 
long, tapering into a slender bristle-like tip, at base, in front 
protuberant, forming a rounded mentum. Upper sepal shorter 
than the laterals, about 6 mm long, cymbiform, acuminate, acute. 
Petals linear-lanceolate, obtuse, 4 mm long, 1-nerved, somewhat 
thickened at the tip, very finely pubescent. Labellum lingulate, 
about 4 mm long, margin ciliolate, strongly deflexed near the 
middle, base rotund when spread flat. Column minute with two 
erect stelidia. 
MINDANAO, Province of Misamis, Mount Malindang, Major E. A. Mearns 
& W. I. Hutchinson, For. Bur. 4608, flower yellow-white, 2,400 m above sea 
level, June 4, 1906. 
In general habit similar to B. dasypetalum, but very distinct from that 
species in the details of the inflorescence. 
The specimen from Mindanao, Mearns & Hutchinson, For. Bur. 4601, 
referred tentatively to B. adenopetalum Lindl.’ appears to belong here. 
From B. adenopetalum it differs in its larger leaves and in the absence of 
caudate tips to the lateral sepals. According to the brief description of 
B. braccatum given by Reichenbach f. in “Linnaea,” B. lancipetalum appears 
to be distinct from that species. In the Philippines there is a puzzling 
group of Bulbophyllums, all so closely allied that for proper interpretation 
a careful study of many specimens will be necessary. To this group belong 
B. adenopetalum and B. Ramosii characterized by caudate-tipped lateral 
sepals, B. dasypetalum and B. lancipetalum characterized by triangular- 
lanceolate lateral sepals, shortly if at all caudate, and B. braccatum which 
is said to have apiculate petals. At the present time, from material at 
hand, a thorough study of this group is being made which will be published 
in the near future.

This interesting species of the § Cirrhopetalum has come to 
hand from the Island of Polillo. The leaves are very thick, 
elliptic or nearly orbicular, 3 cm long by 17 mm wide or there- 
abouts, very shortly petioled, arising from diminutive, rugose, 
pyriform pseudobulbs, 1 cm long. Scape 1.5 to 2 dm tall, 
slender, with several minute, closely appressed, acute bracts. 
Umbel many-flowered, nodding. Bracts of the umbel linear, 
about 8 mm long, crowded. Pedicel slender, together with the 
ovary 5 mm long. Lateral sepals ligulate, 2 em long. Upper 
sepal 5 mm long, lanceolate, prolonged into a slender, bristle- 
like tip, 3-nerved. Petals lanceolate, acuminate, acute, 3-nerved, 
about 3.5 mm long, margin of the upper half entire, margin of 
"Orchidaceae 2: 206.
