AMES. 
Bulbophyllum (§ Monanthaparva) halconense Ames sp. nov. 
Rhizome thread-like, less than 1 mm. thick. Pseudobulbs 1-3 cm. 
apart, round-pyriform when mature, rugose when dry, about 5 mm. 
long, about 4 mm. in diameter at base. Leaves narrowly elliptic-oblong, 
very fleshy (not apiculate), 1.5-2. 5 cm. long, 4-6 mm. wide, acute, con- 
tracted into a very slender petiole. Scape exceeding the pseudobulbs, 
filiform, 1.5-3 cm. long, sheathed at base. Flower solitary, relatively 
large. Pedicel filiform, subtended by a tubular, obliquely truncate, apic- 
ulate bract dilated at its mouth. Lateral sepals narrowly lanceolate, 
caudate-tipped, 12-14 mm. long, about 3 mm. wide near the base. Upper 
sepal similar to the laterals, 12-14 mm. long, caudate-tipped. Petals 
ovate, acute, 5 mm. long, 2.5 mm. wide. Labellum lanceolate from a s 
cordate base, acute, dilated at the middle, 3.5-4 mm, long, 2 mm. wide. 
( From dried speciments it appears to have been strongly convex in life. ) 
Column short with a minute tooth in front at about the middle. 
On trees in ridge forest, flowers dark purple, at 4,500 ft. alt. on Mount Hal- 
con, Nov. 16, 1906, Merrill (No. 5832). On the same sheet with the type is 
a small species of the Monanthaparva section with much smaller flowers and 
shorter scapes. 
Bulbophyllum (§ Racemosae) Merrittii Ames sp. nov. 
Near B. cylindraceum Lindl. Roots copious. Rhizome creeping. 
Pseudobulbs small, about 1 cm. long, about 5 mm. thick, when mature 
surrounded by the elongated fibrous remains of. sheathing bracts. Leaves 
coriaceous, 7-16 cm. long, 2-3.2 cm. wide, rounded at the tip, gradually 
tapering into the comparatively slender, about 3 cm. long petiole. Scape 
slender, exceeding the leaves, provided with several distant, closely ap- 
pressed bracts. Bracts of the inflorescence minute, triangular, 1 mm. 
long, acute. Flowers in a dense, slender, 4-5 cm. long raceme. Lateral 
sepals strongly deflexed, ovate-falcate, subobtuse, 3-nerved, 2.5-3 mm. 
long, 1.25 mm. wide near the middle. Upper sepal ovate-lanceolate, 
subobtuse, 2.75-3 mm. long, about 1.5 mm. wide at base. Petals oblong, 
obtuse, 1-nerved, 1.5 mm. long, 0.75 mm. wide. Labellum lingulate, 
1.5 mm. long, 1 mm. wide, rounded-obtuse at the tip, very fleshy with 
two callus-like thickenings at base. Column minute. 
At 1,475 ft. alt. on Mount Halcon, June 15-27, 1906, M. L. Merritt (No. 4338). 
Bulbophyllum (§ Monanthaparva) mindorense Ames sp. nov. 
Rhizome inconspicuous/ concealed by the depressed, 3-4 mm. long 
pseudobulbs, which form a continuous, sometimes branching chain, 
which is closely appressed to the bark of trees on which the species is 
epiphytic. Leaves lanceolate, acute, 6-8 mm. long, up to 3 mm. wide, 
shortly petiolate. Scapes filiform, up to 4 cm. long. Flower with a 
very long pedicel, apparently wihout a subtending bract, the pedicel
