NEW OR NOTEWORTHY ORCHIDS 
mucronate at the rounded apex, chartaceous, mid-nerve sul- 
cate above and prominently carinate beneath; petiole 1-2 
cm. long, slender, 1-jointed near the middle. Inflorescences 
solitary, subequaling or surpassing the leaf, 4.7-5.5 cm. long. 
Peduncle up to the raceme 2.4-3.5 cm. long, filiform, with 
2-3 scarious infundibuliform sheaths. Raceme short, often 
flexuous. Flowers very small. Sepals ovate, 1.7-1.8 mm. 
long, acute or subacute, strongly cucullate, 1-nerved, dor- 
sally keeled. Petals linear-lanceolate, falcate, 1.6-1.7 mm. 
long, subacute, 1-nerved. Labellum simple, ovate, 1.6-1.8 
mm. long, subacute, densely papillose on the inner surface. 
Column short, stout. 
Pleurothallis ovatilabia is closely allied to P. stenostachya 
Reichb. f., but it is distinct in having solitary inflorescences 
which are relatively elongate and even sometimes surpass 
the leaf. It differs from P. lancilabris (Reichb. f.) Schltr. in 
its larger leaves, shorter pedicels and ovate, acute (not lan¬ 
ceolate, acuminate) perianth-segments. 
Herbarium specimens furnished this diagnosis. 
Honduras, Department of Copan, Loma del Guano, 
between Los Ranchos and Stac. El Limon, if. Piitier 8456, 
May 6-7, 1919. “Epiphyte. Elowers yellow.” (This collec¬ 
tion consists of a dwarf, apparently immature plant up 
to 2.5 cm. tall, with leaf-blades up to 1.8 cm. long.) 
Costa Rica, Province of Cartago, Vicinity of Pejivalle, 
Paul C. Standley & Juvenal Valerio 47213a, February 7-8, 
1926. About 900 meters altitude. (Type in Herb. Ames 
No. 23640.) 
Panama, Province of Chiriqui, Forests around El 
Roquete, H. Pittier 2990, March 4, 1911. 1000-1300 me¬ 
ters altitude. “Epiphytic. FI. small, yellow, in unilateral 
spikes.” (This collection was determined by Schlechter as 
“Pleurothallis lancipetala (R. f.) Schltr.”) This name is 
obviously an error and was doubtless intended for P. lanci¬ 
labris.
