NEW OR NOTEWORTHY ORCHIDS 
Restrepia Lankesteri A. & S. sp. nov. lierba caespi- 
tosa. Caules vaginis distichis laxis scariosis omnino obtecti. 
Folium singulum, erectum, elliptico-ovatum. Inflorescentiae 
uniflorae, folium aequantes, plures. Flos grandis. Sepala 
lateralia libera vel in laminam oblanceolato-oblongam 
bidentatam connata. Sepalum dorsale lanceolatum, longe 
clavato-caudatum. Petala sepalo dorsali similia, minora, 
in basi utrinque unidentata. Labellum trilobatum; lobi 
laterales parvi, falcato-lanceolati, incurvi; lobus intermedins 
oblongus, in apice truncatus, prope basim suborbiculari- 
dilatatus. 
Plant with a creeping rhizome and crowded stems, up 
to 18 cm. tall to the tip of the erect leaf. Roots fibrous, 
flexuous, glabrous, numerous. Stems up to 12 cm. long, 
monophyllous, entirely concealed by distichous sheaths 
which are very loose, conduplicate, scarious and approxi¬ 
mate or somewhat imbricating. Leaf elliptic-ovate, shortly 
petioled; lamina 4-5 cm. long, 1.72-2.9 cm. wide, obtuse 
with a minutely tridenticulate apex, rounded or slightly 
cuneate at base, coriaceous, thick and fleshy in the living 
state, mid-nerve conspicuously sulcate above and carinate 
beneath. Inflorescenses 1-flowered, commonly several, about 
equaling the leaf. Peduncle filiform, naked above the base 
which is clothed with 3 tubular imbricating membranaceous 
sheaths of which the lowest one clasps all the peduncles. 
Ovary mostly concealed by a close tubular membranaceous 
sheath. Flower large for the genus. Sepals and petals with 
a slight fleshy thickening at the very base. Lateral sepals 
apparently free or connate into a lamina which is oblanceo- 
late-oblong, about 2.6 cm. long, 9.1 mm. wide above the 
middle of the lamina, bidentate with obtusely acute apices, 
concave at base, 12-nerved beyond the middle. Dorsal sepal 
lanceolate with an elongate caudate tip, 2.52-2.68 cm. 
long, about 3 mm. wide near the base, unicarinate dorsally, 
5-nerved; the cauda fdiform, 1.42-1.62 cm. long, fleshy with 
a thickened ellipsoid apex. Petals similar to the dorsal sepal 
but much smaller, nearly 2 cm. long, about 1.5 mm. wide 
near the base, 3-nerved with the lateral nerves marginal.
