rounded below with a very short petiole, marginate, 
chartaceous; lamina up to 2.8 em. long and 1.45 em. 
wide; petiole channelled, up to 8 mm. long. Inflores- 
cences one to several, axillary, very short, reaching to 
about the middle of the leaf, 1- to 8-flowered. Flowers 
rather small. Sepals glabrous, membranaceous. Dorsal 
sepal oblong-ovate, abruptly acute, 3-nerved, about 4 
mm. long and 2.1 mm. wide. Lateral sepals a little small- 
er, very obliquely ovate, abruptly acute, 2-nerved, con- 
nate near the base, about 8.5 mm. long and 2.4 mm. wide 
near the base of the free part. Petals smaller than the 
sepals, transversely bilobed with lobules horizontal, about 
1.3mm. long, up to3 mm. wide; posterior lobe obliquely 
ovate to suborbicular, broadly obtuse to rounded; ante- 
rior lobe obliquely triangular-ovate, obtuse, about as long 
as but narrower than the posterior lobe. Lip adnate to 
the column near the base, 3-lobed; lateral lobes peltate, 
with an obliquely triangular claw and a narrowly oblong 
apex (slightly broader toward the front) which is about 
2 mm. across; mid-lobe much smaller, elliptic, deeply 
concave, finely pubescent without. Column arcuate, 
slightly dilated above, about 1.8 mm. long. 
Lepanthes pumila appears to be very similar to the 
Bolivian L. stdlarensis Schltr., but usually has larger pro- 
portions throughout, especially much broader leaves and 
petals and a rather dissimilar lip. It differs from 1. dui- 
densis A. & S. and L. Schnittert Schltr. in its larger size, 
2- to 8-nerved sepals and dissimilar petals. It varies from 
the Costa Rican L. decipiens A. & S. in its commonly 
larger size and in its dissimilar lateral sepals and petals.
