from all in its entire linear lip.

(Type in U. S. Nat. Herb. No. 1205899.) 
Brassia parviflora A. & S', sp. nov. Herba mediocris 
sed floribus parvis. Radices crassae. Folia in basi congesta, 
imbricantia, disticha, vaginis conduplicatis articulata; 
lamina lanceolato-oblonga, breviter acuminata. Scapus 
quam folia multo brevior. Bracteae racemi pauciflori ova- 
ria pedicellata superantes. Sepala lateralia lanceolato- 
linearia. Sepalum dorsale anguste lanceolatum. Petala 
oblique lanceolato-oblonga. Labellum elliptico-lanceolatum, 
dimidio inferiore carinis binis conspicuis ornatum. 
Plant caespitose, medium-sized but with very small 
flowers, about 35 cm. tall to the apex of the erect leaf. Roots 
very stout, fibrous, 2-2.5 mm. in diameter. Pseudobulbs 
apparently lacking. Leaves crowded at the base, densely 
imbricated, distichous, articulated to membranaceous con- 
duplicate striate-nervose sheaths; blade lanceolate-oblong, 
8-27.6 cm. long, 14-29.5 mm. wide (the outer blades suc¬ 
cessively smaller with the outermost very small), short- 
acuminate above, slightly narrowed to a eonduplicate base 
or very gradually narrowed to a channelled petiole. Inflores¬ 
cence half the length of the larger leaves. Peduncle below 
the raceme 13-14 cm. long, lower half concealed by the leaf- 
sheaths, exposed upper half with one or two loose tubular 
scarious sheaths. Rachis 5.2 cm. or less long, 3- to 5-flow- 
ered. Floral bracts conspicuous, lanceolate, the lowermost 
1.9-2.1 cm. long, much surpassing the pedicellate ovary, 
acuminate, eonduplicate, scarious, nervose. Flowers very 
small for the genus. Lateral sepals lanceolate-linear, with 
recurved apices, 1.76 cm. long when extended, 2.1 mm. wide 
near the base, gently falcate, 1- to 3-nerved, fleshy in the 
longitudinal middle, and subcarinate dorsally. Dorsal sepal 
narrowly lanceolate, 1.41 cm. or more long, 2.8-3 mm. wide.
