AMES. 
scarious, sheathing the stem. Peduncle sparsely pubescent, with about 3 
lanceolate, scarious, about 1 cm. long bracts below the loose, racemose in- 
florescence. Moral bracts linear-lanceolate, acute, scarious, about 1 cm. 
long. Flowers white. Lateral sepals linear-oblong, about 1.2 cm. long, 2 
mm. wide, concave, lightly carinate, cucullate with several hairs at the tip. 
Upper sepal similar to the laterals, broader, adhering lightly to the 
petals. Petals 1.2 cm. long, spathulate, obtuse, linear below the middle, 
free from each other at the base, cohering above the middle by their inner 
margins. Labellum adhering to the column, produced at base into a 
rather slender bilobed-tipped spur which protrudes between the lateral * 
sepals; free portion narrow, a little dilated beyond the column, then 4- 
lobed; proximal lobes divaricate, oblong, obtuse, 1.5 mm. long, 1 mm. 
wide, separated from the distal lobes by a short 1 mm. long claw or 
isthmus; distal lobes divaricate, 1.5 mm. long, about 2 mm. wide, margin 
irregular; on the disc two thin longitudinal lamellae, free at the ob- 
liquely truncate apex. Two wart-like calli are situated in the spur near 
its base, on the dorsal wall. From tip of spur to apex of labellum 
1.5 cm. 
Terrestrial in damp ravine, by small stream on Mount Haleon, Nov. 9, 1906,

Cheirostylis octodactyla Ames sp. nov. 
Eelated to C. Griffithii Lindl. Plants rather stout in relation to their

cm. long, 5-11 mm. wide, 5-6 mm. apart on the stem. Petioles short, 
sheathing at base. Flowers one or two, white, 1 cm. long, standing at 
right angles to the erect stem. Lateral sepals united nearly to the apex, 
lanceolate, subacute, 8 mm. long. Upper sepal oblong-lanceolate, acute, 
somewhat dilated near the base, 8 mm. long. Petals lightly adhering 
to the upper sepal, linear-spathulate, about 8 mm. long, 2 mm. wide near 
the tip. Labellum linear-oblong, about 9 mm. long to the tip of the 
slightly dilated 8-fingered apex, 2.5 mm. wide at base; on each side a 
row of 7-8 setae. Digitate divisions of the apex 3 mm. long.
