NEW OR NOTEWORTHY ORCHIDS 
gatae, permagnae, flores excedentes. Flores flavi. Sepala 
lateralia anguste oblonga, apice cymbiformi. Sepalum 
dorsale simile. Petala leviter curvata, anguste oblonga, ob- 
tusa. Labellum in basi sagittatum, supra basim dilatatum, 
supra medium contractum, apice obtuso, extus per medium 
carinatum. Discus prope medium minute glandulosus. 
Columna generis. 
Epiphytic herb, 30-37 cm. tall. Roots fleshy, densely 
white-villose. Leaves long-petiolate; lamina elliptic-lan¬ 
ceolate or ovate-lanceolate, acuminate, acute, 9-15 cm. long, 
' 3-6 cm. wide, membranaceous, often asymmetrical, erect or 
recurved; petioles 8-14 cm. long, slender, sulcate, clasping or 
sheathing at the base, more or less equitant. Peduncle (in¬ 
cluding the raceme) 28-40 cm. long, glabrous, erect, stout, 
almost entirely concealed by elongated bracts, bearing at the 
summit a dense bracteate raceme. Bracts of the peduncle up 
to 11.5 cm. long, about 1 cm. wide, closely appressed, obtuse 
or subacute, tubular at the base. Raceme about 6.5 cm. 
’ long. Bracts of the raceme about 5 cm. long, 6-12 mm. wide, 
narrowly oblong-lanceolate, acute, much exceeding the flow¬ 
ers, obliquely ascending, glabrous. Flowers yellow, about 
2.5 cm. long, with the perianth segments more or less conni- 
vent. Ovary glabrous. Lateral sepals 2.5 cm. long (includ¬ 
ing the blunt mentum), 5 mm. wide, narrowly oblong-cymbi- 
form and shortly carinate at the tip, glabrous. Dorsal sepal 
about 2.5 cm. long, narrowly oblong, acute, adhering lightly 
to the petals, glabrous. Petals about 2 cm. long, 3 mm. wide, 
obtuse, 1-nerved, narrowly oblong, somewhat curved. Label¬ 
lum 2.5 cm. long, conspicuously dilated above the sagittate 
base, then gradually narrowed upward to the obtuse tip, dis¬ 
tinctly carinate through the basal half on the outer surface 
and densely but minutely glandulose; auricles of the sagit¬ 
tate base 1.5 mm. wide, obtuse, conspicuously thickened on 
the outer half. Disc densely and minutely glandulose below 
the middle. Column 2 cm. long, conspicuously glandular- 
hairy on the inner surface. 
Among Costa Rican species, Stenorrhynchus Standleyi is 
niost closely related to S. bracteosus Ames & Schweinf., but
