long time.” Flowers yellow inside, reddish yellow outside. 
(Type in Herb. Ames No. 28136.) 
Maxillaria foliosa A. & S. sp. nov. Herba caespitosa. 
Caules ramosi, vaginis foliorum omnino obtecti. Pseudo- 
bulbi rari, elliptico-complanati, vulgo bifoliati. Folia nume- 
rosissima, disticha, oblonga. Flores axillares, rari. Sepala 
oblonga, acuta, lateralia obliqua. Petala falcato-oblonga, 
minora. Labellum supra medium obscure trilobatum, trun- 
cato-rotundatum. Columna generis. 
Plant 15-18 cm. tall. Roots numerous, slender, fibrous, 
longitudinally sulcate, glabrous. Stems caespitose, branching, 
entirely concealed by striate-rugose leaf-sheaths. Pseudo¬ 
bulbs ellipsoid, strongly flattened when dry, about 1.5 cm. 
long, erect-ascending, usually diphyllous, commonly about 
2 cm. apart on the branches (some branches have none), dull, 
rugose. Leaves small, distichous, dense, spreading, caducous 
on the lower parts of the stem and branches, oblong to 
lanceolate-oblong with abruptly clasping bases, commonly ijj > 
2-3 cm. long (rarely up to 4.8 cm. long), about 5 mm. wide, 
rounded above with an obliquely bilobed apex, subcoria- 
ceous, the mid-nerve conspicuously sulcate above and cari- 
nate beneath. Flowers growing singly in the axils of the ' 
upper leaves, very sparse, pale yellow-green. Lateral sepals 
oblong, about 9 mm. long, 4 mm. wide, lightly falcate- 
oblique, acute at the rounded apex by reason of a dorsal 
mucro, 9-nerved with five nerves more prominent. Dorsal 
sepal similar. Petals oblong, lightly falcate, 8 mm. long, 
about 3 mm. wide, rounded above, with a minute dorsal 
mucro, 3-nerved with a weaker nerve on each side. Labellum 
oblong, dilated above the middle and consequently very 
obscurely 3-lobed, the dilated margins involute, about 8.8 
mm. long, about 3.6 mm. wide across the dilated portion ’ 
when spread out; apical lobe subquadrate, subtruncate, 
about 2.8 mm. long, about 3.2 mm. wide near its base; disc 
with a low callus in the middle, minutely papillose near the 
margins of the lateral lobules and near the apex of the la- 
bellum. Column stout, about 5.2 mm. long, anterior face 
concave, curving into a foot.
