NEW OR NOTEWORTHY ORCHIDS 
or more long, with several ovate-lanceolate smooth somewhat 
spreading bracts. Racemes about 7 cm. long. Bracts of the 
raceme 5 mm. long, smooth or only sparsely glandular along 
the margin. Lateral sepals 7.5-8 mm. long, 3 mm. wide at 
the base, triangular-ovate, forming a conspicuous mentum 
which is 2.5 mm. long and obtuse. Dorsal sepal about 8 mm. 
long, lanceolate, subacute, strongly concave at the base, 
more than twice longer than the column. Petals 7.5 mm. 
long, 2 mm. wide below the middle, elliptic-lanceolate from 
a broad base, subacute, 3-nerved. Labellum 6 mm. long, 
about 4 mm. wide near the base, broadly ovate, obtuse, 
with the margin on each side — near the middle — coarsely 
and unequally dentate, 3-nerved, the lateral nerves much 
branched. Disc ecallose. Column fleshy, 3 mm. long, pro¬ 
duced at the base into an elongated foot. 
The nearest ally of this species is Eria philippinensis 
Ames, which has much larger flowers, different leaves and 
stouter stems which are provided with swollen sheaths. 
From E. vagans Ames it differs in habit. The structure of 
the labellum suggests E. dagamensis Ames, but from that 
species it is quite distinct in habit.
