at base near the apex of the column foot, about 8 mm. long, 2.5 mm. 
wide near the middle, broader below. Upper sepal lanceolate, acute, 
about 9 mm. long, narrower than the laterals. Petals linear-lanceolate, 
or linear-oblong, subobtuse, 3-nerved, about 8 mm. long, 2 mm. wide 
near the middle. Labellum ecallose, smooth, 5 mm. long, basal half 
with the sides erect (conduplicate when dry), apical half oblong, rounded 
at the apex, 2 mm. wide. 
Terrestrial in mossy ridge forest at 7,000 ft. alt. on Mount Halcon, very 
abundant but only one plant found in flower, flowers white, base of tube purple 
within, Nov. 16, 1906, Merrill (No. 5514). 
Eria (§ Convolutae) Merrillii sp. nov. 
Pseudobulbs about 1 dm. long, very stout, compressed, 3 cm. or more 
in diameter, diphyllous (sometimes bearing more than 2 leaves). Leaves 
oblong-lanceolate, about 3 dm. long (up to 6 dm.), 4-7 cm. wide. 
Peduncle comparatively stout, arising from near the summit of a pseu- 
dobulb (erect? or drooping?), bearing numerous very large, nearly white, 
somewhat purple-tinged flowers in a dense, elongated raceme. Raceme 
about 3 dm. long. Bracts triangular-lanceolate, acute, 1.5-2 cm. long, 
about 4 mm. wide at base. Ovary very strongly winged, distantly 
resembling an auger on account of the spiral turnings of the wings. 
Lateral sepals 1.5 cm. long, linear-falcate, tapering to an acute apex 
from a 6 mm. broad base. Upper sepal linear, 1.9 cm. long, 3 mm. 
wide, tapering' gradually to an obtuse tip. Petals similar to the lateral 
sepals, 1.6 cm. long, about 4 mm. wide at base. Labellum 11-11.5 mm. 
long, 3-lobed; lateral lobes comparatively small, curved, about 1 mm. 
long, 1 mm. wide, obtuse, 5.5 mm. from the base of the labellum; 
middle lobe 7 mm. -long, 2.5 mm. wide, oblong, acute. Through the 
disc of the labellum extend 5 prominent nerves or carinse. 
Epiphyte at 1,250 ft. alt. along the Alag River, flowers very fragrant, with 
odor of the swamp Habenaria of the eastern United States, Nov. 12, 1907, Merrill 
(No. 5519). 
This robust Eria is allied closely to E. rugosa Lindl., E. striolata Reichb. f., 
E. fragrans Reichb. f., and E. cochleata Lindl. The strongly developed, spirally 
twisted wings of the ovary are very curious and quite distinctive of this species 
and E. cochleata. 
Eria (§ Hymeneria) Merrittii Ames sp. nov. 
Pseudobulbs rather stout, cylindrical from a stout rhizome, 7-10 cm. 
long, about 5 mm. thick, 2-3-leaved at the summit. Leaves linear- 
lanceolate, about 12 cm. long, about 1.5 cm. wide, acuminate, acute. 
Peduncle short, about 4 cm. long, breaking forth from the upper part 
of the pseudobulbs. Bracts lanceolate, acute. Flowers white. Lateral 
sepals linear-lanceolate, acute, about 6-7 mm. long, 1.5 mm. wide at 
base. Upper sepal linear-lanceolate, about equal to the laterals. Petals
