NEW OR NOTEWORTHY ORCHIDS 
petioled, but the drawing shows a sessile lamina, and the 
type specimen in our herbarium has a leaf with a narrowly 
cuneate, scarcely petioled base. The lip, moreover, is not 
about 1.5 mm. long as cited, but almost 3 mm. long, and is 
thus nearly as large as the lip of P. dentipetala. 
Pleurothallis fractiflexa A. & 5. sp. nov. Herba 
parva, epiphytica, caespitosa. Caules minuti, monophylli. 
Folium spathulato-oblanceolatum, inferne sensim angusta- 
tum. Inflorescentiae plures, axillares, folia multo superantes, 
laxiflorae. Sepala lateralia in laminam lanceolato-ellipticam 
bidentatam connata. Sepalum dorsale oblongo-lanceolatum, 
concavum. Petala falcato-lanceolata, apice incrassato pubes- 
centi. Labellum minus, panduratum. 
Plant small, caespitose, 6-7 cm. high. Roots fibrous, 
filiform, flexuous, glabrous. Stems minute, about 4 mm. 
long, enveloped by 2 scarious tubular sheaths. Leaf solitary, 
erect, spatulate-oblanceolate, about 1.3-2.8 cm. long, 2.5- 
4.6 mm. wide, acute and obscurely tridenticulate at the 
apex, very gradually narrowed to a petioled base, margined, 
coriaceous. Inflorescences very flexuous, twice surpassing 
the leaf or more, filiform, lax; rachis fractiflex, 2- to 28- 
flowered, flowers loose. Lateral sepals connate into a lan¬ 
ceolate-elliptical lamina, about 6 mm. long, bidentate with 
acute teeth, dorsally bicarinate, sparsely ciliate, rather 
closely pubescent through the center within, 4-nerved. Dor¬ 
sal sepal oblong-lanceolate, 6.4-7 mm. long, 2 mm. wide 
near the base, acute, 3-nerved, unicarinate on the outer sur¬ 
face, concave, ciliate. Petals falcate-lanceolate, 5.1-5.8 mm. 
long, about 1.2 mm. wide across the oblong basal part, 
rather abruptly narrowed into the anterior half which is 
linear, apical portion slightly dilated, much thickened, sub- 
terete and pubescent, 1-nerved. Labellum pandurate, some¬ 
what convex in natural position, about 2.6 mm. long; claw 
minute oblong, membranaceous; lamina with a pair of slender 
auricles at base, broadly rounded at the apex, margins of 
the basal half somewhat erect and minutely pubescent, those 
of the anterior half revolute and long-ciliate. Disc trav-
