NEW OR NOTEWORTHY ORCHIDS 
Stems filiform, up to 4 cm. tall, composed of about 5-7 in¬ 
ternodes, closely enveloped in tubular sheaths which are 
minutely hispid on the nerves and end in spreading in- 
fundibuliform hispid mouths. Leaf solitary, cuneate-spatu- 
late, obovate or elliptic, the largest reaching nearly 2 cm. 
long and 9 mm. wide, obtuse, shortly petioled. Inflores¬ 
cences commonly 1-3 (rarely 5 peduncles are present), fili¬ 
form, more or less surpassing the leaf, up to 7.8 cm. long in¬ 
cluding the raceme (though generally much shorter), usually 
arcuate or diffuse. Rachis fractiflex, up to 6.1 cm. long and 
31-flowered (sometimes very short and apparently 2- to 
3-flowered). Lateral sepals obliquely ovate-lanceolate, about 
one-half connate, 3.2-3.9 mm. long, abruptly acuminate or 
shortly caudate with more or less incurved apex, 2-nerved, 
the nerves marked dorsally by low denticulate keels. Dor¬ 
sal sepal ovate, cucullate, about 4.2 mm. long, 2.8-3.8 mm. 
wide, abruptly acute, 3-nerved, the nerves bearing denticu¬ 
late keels on the outer surface. Petals very irregularly sub¬ 
quadrate with the upper margin bilobed, about 1.9 mm. 
long measuring the longer anterior margin which extends 
into an obtuse point, subequally wide, base truncate. The 
posterior portions of the petals overlap in the natural posi¬ 
tion. Labellum very minute, simple, reniform or reniform- 
ovate, apiculate, .5 mm. long, .8-9 mm. wide. Column 
shorter than the petals, much larger than the labellum; 
clinandrium enlarged. Anther pyriform, 2-celled. Pollinia 
2, pyriform. Ovary with 6 denticulate or erose keels. 
The description was made from a large series of dried 
specimens supplemented by flowers preserved in formalin. 
Lepanthes minutilabia recalls L. Jimenezii Schltr. in 
habit, but it differs from that species in having relatively 
smooth stems and very dissimilar flowers. The minute lip 
is remarkable.
