ulis obtecti. Folium ovatum, acuminatum, apice in dentes 
tres subaequales divisum. Petioli plus minusve duo. Ra- 
cemus abbreviatus. Flores distichi, succedanei. Sepala 
lateralia usque ad medium cohaerentia, ovata, acuminata, 
valde acuta, in sicco diaphana. Sepalum dorsale ovato- 
lanceolatum, acutum. Labellum trilobatum; lobis lateralibus 
subquadratis, valde obtusis; lobo medio valde incrassato, 
glanduloso, abbreviate. Columna gracilis. 
Plant epiphytic, up to 9.5 cm. high. Roots fibrous, 
whitish. Secondary stems 1.5-7 cm. long, monophyllous, 
very slender, the longer ones with six closely oppressed 
sheaths which are hispidulous longitudinally along the 
prominent nerves, dilated at the summit, terminating in 
an acute tip, purplish when dry. Leaf 2-3 cm. long, up 
to 1.7 cm. wide, coriaceous, ovate, acuminate, subequally 
tridentate at the apex, contracted at base into a short 
sulcate petiole. Peduncles one to three, shorter than the 
leaf, with the raceme about 1.5 cm. long, very slender. 
Bracts of the inflorescence minute. Flowers distichous, 
crowded, opening in succession. Lateral sepals about 2 mm. 
long, coherent to about the middle, ovate, acuminate, 
acute, 3 mm. wide from margin to margin at the point of 
coalescence (free portion of each sepal 1.5 mm. wide). 
Dorsal sepal 2.5 mm. long, 2 mm. wide, ovate-lanceolate, 
acute, 1-nerved. Petals 1 mm. long, about 2 mm. wide, 
deeply bilobed or crescentiform, the lobes obtuse. Labellum 
1 mm. long, 3-lobed; lateral lobes oblong, subquadrate, 
obtuse, much exceeding the middle lobe, carinate on the

In habit Lepanthes appendiculata resembles L. sama- 
censis Ames, but differs from it in the form of the petals and 
labellum. In the shape of the petals it is comparable to 
L. acuminata Schltr.
