AMES. 
long, 3 mm. wide near the base, oblong-lanceolate, acute. Upper sepal 
about 9 mm. long, ovate-lanceolate, acute. Petals narrowly lanceolate, 
slightly carinate dorsally along the median nerve, 7 mm. long, about 2.5 
mm. wide. Labellum 7 mm. long, apex strongly deflexed, subacute, 
saccate ; lamina somewhat rhombic in outline, intramarginally bicarinate. 
In humid forest, terrestrial, at 900 ft. alt. along the Binabay River, Nov. 2, 
1906, Merrill (No. 5552). 
In habit T. mindorensis recalls T. graminea BL, differing from our species 
mainly in its smaller, terminal raceme and flowers. The measurements given 
above for the height of the plant apply to specimens which appear to have been 
broken. Specimens with roots were not collected by Mr. Merrill. 
NEPHELAPHYLLUM Bl. 
Nephelaphyllum mindorense Ames. sp. nov. 
Closely allied to N. pulchrum Bl. 
Plants about 2 dm. tall. Ehizome creeping, slender, rooting at in- 
tervals. Stems purple. Leaves with the under surface uniformly dark 
purple, upper surface mottled, ovate-lanceolate, acuminate, acute, 8-10 
cm. long, 3—5.5 cm. wide near the base. Petioles relatively slender, 
about 3 cm. long. Peduncles exceeding the leaves, clothed with several 
scarious, tubular, acute sheaths. Inflorescence loosely few-flowered. 
Bracts about 1 cm. long, linear, acute, scarious, somewhat shorter than 
the pedicels of the white flowers. Lateral sepals linear-acute, 1-nerved, 
9 mm. long, 1.5 mm. wide. Upper sepal similar and equal to the 
laterals. Petals oblong, acute, slightly broader above than below the 
middle, 1-nerved, about 8 mm. long, 3 mm. wide. Labellum suborbi- 
cular, entire 9-10 mm. long, 9-10 mm. wide, with 3 prominent con- 
verging lamellae near the apex, which pass basally into the main nerves 
of the hairy disc. Spur blunt, inflated, 4-5 mm. long. 
Terrestrial in humid forest at about 900 ft. alt. along the Binabay River, 
Nov. 2, 1906, Merrill (No. 5623). 
CHRYSOGLOSSUM Bl. 
Chrysoglossum villosum Bl. Bijdr. 338, f. 7 (1825). 
Terrestrial, flower odorless, or nearly so, petals twisted, dark purple in the 
middle, Binabay River, Nov. 2, 1906, Merrill (No. 5838). — Mount Halcon, June 
15-27, 1906, M. L. Merritt (No. 4398). 
The specimens on which the above determination is based agree too well with 
G. villosum Bl. to be separated from it specifically. 
Java, Borneo, Perak. 
DENDROCHILUM Bl. 
Dendrochilum (§ Platyclinis) arachnites Reichb. f. Gard. Cliron.. n. s. 17: 
256 (1882). 
Epiphyte at 6,800 ft. alt. on Mount Halcon, flowers pale greenish, odorless, 
Nov., 1906, Merrill (No. 5511). 
Endemic in the Philippines.
