Lepanthes grandiflora A. & S. sp. nov. Herba caes- 
pitosa, parvula. Caules monophylli, vaginis tubulatis 
arctis pubescentibus omnino inclusi. Folium ovatum vel 
ellipticum, in vivo valde crassum. Pedunculi breviores, 
biflori. Flos grandis. Sepala lanceolata, valde attenuata, 
in dorso carinata. Petala transverse bilobata; lobi oblongi, 
lobus anterior longior. Labellum minus, trilobatum; lobi

Plant caespitose, small, up to 8 cm. tall to the tip of the 
erect-spreading leaf. Roots fibrous, flexuous, filiform, mi¬ 
nutely pubescent. Stems slender, monophyllous, up to 5.5 
cm. high, entirely concealed by 7 or less sheaths which are 
close tubular and pubescent on the longitudinal nerves with 
dilated hispid infundibuliform mouths. The latter are con¬ 
spicuous in the fresh plant. Leaf elliptic to broadly ovate, 
shortly petioled; lamina up to 2.3 cm. long, 1.3 cm. or less 
wide, acute and minutely tridenticulate at the apex, cuneate 
or rounded at base, very fleshy in the fresh specimen. In¬ 
florescences commonly solitary (occasionally remnants of 
several old ones appear), 2-flowered at the summit, with an 
abortive terminal flower. Peduncle shorter than the leaf 
(usually much so), filiform. Flowers very large for the plant, 
when spread out up to 3.7 cm. wide from the tip of the dor¬ 
sal sepal to the apex of the lateral ones. Sepals widely 
spreading, the margins ciliolate. Lateral sepals connate 
near the base, lanceolate, long attenuate above, 1.5-1.82 
cm. long, 4-5 mm. wide at base of free portion, oblique, 
3-nerved, the mid-nerve dorsally carinate. Dorsal sepal 
similar, 1.57-1.79 cm. long, 4.6-5.4 mm. wide near the base, 
3-nerved, the mid-nerve with a ciliolate keel on the outer 
surface. Petals relatively minute, transversely bilobed, 4.6-6 
mm. wide from tip to tip, very minutely pubescent; posterior 
lobe oblong to oblong-ovate, broadly rounded at its apex;
