ORCHIDACEAE QUAEDAM AMERICANAE 
appressed to the labellum, angulate on each side below the 
summit. 
Allied to Epidendrum tampense Lindh, from which it 
differs in having smaller flowers and the peduncle much 
shorter than the leaves. The column is minutely angled on 
each side, in front, so as to suggest rudimentary divaricate 
stelidia. 
Panama, Province of Chiriqui, Alanje, H. Pittier s. n. 
(Type from plant cultivated in Washington, D. C., U. S. 
Nat. Herb. No. 716250.) 
Epidendrum colonense Ames sp. nov. Caules rigidi. 
Folia disticha, ligulata, obtusa. Flores terminales, duo, 
Sepala petalaque lineari-oblonga. Labellum trilobatum; 
lobi laterales semiovati; lobus medius anguste lanceolatus, 
sulcatus, nervo prominent! in medio. Columna abbreviata, 
crassa. 
Roots fibrous, branched, smooth. Stems about 2 dm. tall, 
stout. Leaves about 4.5 cm. long, up to 1.3 cm. wide, very 
thick, much wrinkled when dry, ligulate, rounded at the tip, 
deeply sulcate through the middle, jointed to the rigid 
closely appressed sheaths, distichous, 1-1.5 cm. apart. 
Flowers terminal, apparently in pairs, each flower subtended 
by a rigid complanate spathaceous bract. Pedicel with the 
ovary 1 cm. long, rigid. Lateral sepals about 1.4 cm. long, 
2 mm. wide, linear-oblong, tapering gradually to an acute 
tip, very fleshy, rigid, many-nerved. Dorsal sepal similar, 
obtuse. Petals 1.4 cm. long, 2 mm. wide, similar in texture 
to the sepals, linear-oblong, subacute, many-nerved. La¬ 
bellum 1.4 cm. long, 3-lobed; lateral lobes semiovate, 5 mm. 
long, obtuse, each forming a deep sinus with the middle lobe, 
its blunt apex porrect; middle lobe 9 mm. long, 3 mm. wide 
near the middle, narrowly lanceolate, acute, deeply sulcate, 
with a conspicuously raised median nerve, which passes to 
the base of the labellum and forms two distinct divergent 
ridges; on either side of the middle lobe near the base is a 
distinct callus-like thickening. Column about 3 mm. long, 
stout, toothed at the tip.
