ORCHIDACEAE QUAEDAM AMERICANAE 
Pleurothallis abjecta Ames sp. nov. Herba epiphyt- 
ica, dense caespitosa. Caules secundarii abbreviati, mono- 
phylli. Folium in petiolum sulcatum productum; lamina 
elliptica, marginata, apice breviter apiculata, coriacea, 
quam pedunculus brevior. Pedunculus singulus, fili- 
formis, infra flores nudus. Flores subfasciculati vel in 
racemum valde abbreviatum contracti, purpureo-tincti. 
Sepala lateralia usque ad medium vel supra medium cohae- 
rentia, laminam ellipticam formantia. Sepalum dorsale 
valde concavum, quam sepala lateralia multo angustius. 
Petala triangulari-lanceolata, acuminata, acuta. Label- 
lum anguste linguiforme, per medium sulcatum, utrinque 
prope marginem incrassatum, obtusum, margine dense 
pilifero. Columna in pedem brevem producta, apice den¬ 
ticulate. 
Plants densely caespitose with slender spreading whitish 
roots. Secondary stems slender, up to 5 mm. long, clothed 
with scarious sheaths which soon pass away, monophyl- 
lous. Leaf with the petiole included up to 1 cm. long, 
about 3 mm. wide; lamina 5 mm. long, elliptical, apiculate 
at the tip, strongly marginate, coriaceous, rigid, erect. 
Peduncle single, with the raceme up to 1.5 cm. long, very 
slender, naked below the contracted few-flowered raceme, 
erect, slightly exceeding the leaves. Flowers few, purplish, 
subfasciculate, subtended by infundibuliform scarious acute 
bracts. Pedicels persistent, about 2 mm. long, slender. 
Ovary 2 mm. long, dilated upward from a slender base, 
articulated with the pedicel. Lateral sepals 3-4 mm. long, 
coherent (for about three-fourths or one-half of their length), 
forming an elliptical lamina 2 mm. wide across the middle, 
4-nerved, free tips somewhat convergent, subacute. Dorsal 
sepal 3.5 mm. long, elliptic-lanceolate, elongate-cucullate, 
obtuse, 3-nerved. Petals 3 mm. long, about 1 mm. wide 
near the middle, triangular-lanceolate from a broad base, 
acuminate, acute, 1-nerved. Labellum nearly 3 mm. long, 
hardly 1 mm. wide, up to the base provided with hairs of 
irregular length along the strongly deflexed margin, oblong- 
lanceolate; apex obtuse, entire, with shaggy glandular 
hairs. Disc sulcate to about the middle, thickened on each
