ORCHIDACEiE HALCONENSES. 
329 
Dendrobium sp. 
Material not sufficient for description. 
Epiphyte at 5,000 ft. alt. on Mount Halcon, Nov. 26, 1906, Merrill (No. 
5577). 
The paucity of Dendrobium species in the collections from Mount Halcon and 
its neighborhood is noteworthy. 
ERI A Lindl. 
Eria aeridostachya Reichb. f. ex Lindl. Journ. Linn. Soc. 3: 48 (1859); 
Reichb. f. in Seem. El. Vit. 301. 
Epiphyte at about 6,400 ft. alt. on Mount Halcon, flowers brown-purple, odor- 
less, Nov. 15, 1906, Merrill (No. 5518). 
Philippines and Fiji Islands; also ascribed to Java and the Malay Peninsula. 
Several closely allied species are likely to have been confused in the literature of 
distribution under the name E. aeridostachya. Lindley’s plant and Reichenbach’s 
Seemann plant agree. 
Eria (§ Trichotosia) binabayensis Ames sp. nov. 
Allied to E. oliganthci Hook. f. . Plants rather stout, 4-5 dm. tall. 
Stems about 5 mm. in diameter. Leaves oblong-lanceolate, tapering 
gradually toward the point, about 1 dm. long, 1—2 cm. wide, rigid, 
coriaceous, pubescent. Inflorescence leaf-opposed, clothed with dense, 
cinnabar-red tomentum. Bracts about 1 cm. long. Raceme short, 3 
cm. long, probably becoming longer as the flowers develop. Lateral 
sepals triangular-lanceolate, densely tomentose externally, 1 cm. long, 
about 8 mm. wide at base. Upper sepal oblong, narrower than the 
laterals. . Petals linear-spathulate, subobtuse, 7-8.5 mm. long, 2 mm. 
wide above the middle. Labellum 1 cm. long, narrowly cuneate at base, 
then gradually dilated to within 2 mm. of the tip, where it is con- 
stricted and about 4 mm. wide; above the constriction it is again dilated 
into a transversely oblong, 6-7 mm. wide plate; disc bicarinate. 
Epiphyte in humid forest along the Binabay River, flowers nearly flesh colored, 
the narrow petals white, labellum with yellow-purple spots, Nov. 3, 1906, Merrill 
(No. 5661) . 
It is highly probable that the racemes of the specimens examined had not 
attained their full length when collected. At maturity they most likely resemble 
the racemes of such closely allied species as E. vulpina, E. ferox, and E. velutina. 
Eria (§ Hymeneria) compacta Ames. sp. nov. 
Roots elongated, much branched. Pseudobulbs approximate, elon- 
gated-pyriform, about 5 cm. long, about 1 cm. in diameter at base, 
bifoliate. Leaves rigid, coriaceous, oblong-lanceolate, obtuse, 4.5-5. 5 cm. 
long, 10-14 mm. wide. Inflorescence about 3 cm. long. Bracts ovate- 
lanceolate, 5 -mm. long, about 2 mm. wide, acute, equaling or exceeding 
the pedicels of the flowers. Lateral sepals triangular-lanceolate, acute, 6 
mm. long, 2.5 mm. wide at base. Upper sepal lanceolate, slightly broader
