CENTRAL AMERICAN ORCHIDS 
latiora quam longiora, minute glanduloso-puberula, trans¬ 
verse bilobata, lobo posteriore oblongo, obtuso, lobo an- 
teriore lineari, subacuto. Labellum trilobatum; lobis lat- 
eralibus anguste ellipticis, e medio unguiculatis, per medium 
carinatis ut videtur, glanduloso-puberulis, margine glandu- 
loso-ciliatis; lobo medio partem anteriorem loborum lat- 
eralium vix demidio aequanti, lineari, dense glanduloso, 
apice bulboso. Columna apice valde cuneato-dilatata. 
Pollinia duo, anguste pyriformia. 
Epiphytic herb, caespitose. Roots fibrous. Secondary 
stems erect or ascending, up to 9 cm. long, slender, concealed 
by about ten elongated closely oppressed sheaths which are 
about 7 mm. apart. Sheaths densely muricate, dilated at 
the tip, the expanded portion marginate. Leaf up to 3.5 
cm. long, 9-11 mm. wide, elliptical, tridenticulate at the tip, 
narrowed below into an abbreviated conduplicate base. 
Peduncle up to 4 cm. long, three or more flowered, the 
flowers opening in succession. Raceme up to 2 cm. long, 
flexuose. Pedicels obliquely ascending. Lateral sepals up 
^ to 2.4 cm. long, 6 mm. wide near the base, coherent up to the 
middle, forming a lanceolate-bicaudate lamina, densely 
glandulose-hairy on the upper surface, apparently yellow 
tinged with purple when fresh, fading to yellow as the flowers 
mature. Dorsal sepal about 2 cm. long, up to 6 mm. wide 
near the base, ovate-acuminate, terminating in a slender 
caudate tip, glandular-ciliate on the margin, smooth on the 
inner surface, glandulose on the outer surface on the three 
prominent nerves, the mid-nerve deeply carinate. Petals 
5 mm. wide, hardly .75 mm. long opposite the point of in¬ 
sertion, posterior portion oblong, 2 mm. long, anterior 
portion linear, 3 mm. long. Labellum glandulose, 1.25 mm. 
long, 3-lobed; lateral lobes elliptic, 1.25 mm. long; middle 
lobe porrect between the lateral lobes, linear, half as long 
ns the anterior portion of the lateral lobes, densely glandular. 
Column about 2 mm. long. 
In habit similar to Lepanthcs horrida Reichb. f., from 
which it differs in the middle lobe of the labellum and in the 
outline of the petals. The lateral sepals appear to have 
been yellow suffused with purple, the upper sepal deep
