NEW OR NOTEWORTHY ORCHIDS 
Plant 12-26 cm. tall. Rhizome creeping, terete, the 
younger parts concealed by scarious sheaths which waste 
into fibers in anthesis, up to 3 mm. in diameter. Roots 
fibrous, densely lanuginose. Pseudobulbs cylindric to pyri¬ 
form, finely rugose in the dried plant, about 2.7 cm. long, 
2.2 cm. or more apart, enveloped by a pair of scarious nervose 
sheaths. Stem emerging from beneath the pseudobulb by a 
more or less decumbent base, invested by long sheaths, up 
to the leaves about 4-9 cm. long. Leaves 2, subopposite at 
the summit of sheaths which invest the stem; lamina ovate, 
lanceolate-ovate or elliptic-ovate, 5-7.5 cm. long, 3-4.5 cm. 
wide, acute or abruptly acuminate, subcuneate at base, 
membranaceous, the mid-nerve sharply carinate on the un¬ 
der surface. Peduncle up to the inflorescence erect or slightly 
arcuate, rigid, 7.5-16 cm. long, naked, grooved and very 
narrowly winged. Inflorescence very short, dense, subum- 
bellate, rachis up to 1 cm. long. Floral bracts minute, tri¬ 
angular-lanceolate, scarious. Pedicellate ovary fdiform, 1-2 
cm. long in anthesis, widely spreading, 6-channeled. Flow¬ 
ers minute. Lateral sepals strongly reflexed, ovate or ob¬ 
long-ovate, 3.6 mm. long, about 2 mm. wide, obtuse, very 
obliquely inserted at the base, 3-nerved. Dorsal sepal 
broadly ovate, 3.9 mm. long, about 2.5 mm. wide, obtuse, 
with 3 main nerves. Petals more or less circinate, triangu¬ 
lar-linear, about 3.6 mm. long, obtuse, 1-nerved. Labellum 
strongly concave, about 3 mm. long from base of column to 
apex of lamina, triangular-ovate in outline, broadly truncate 
at base with erect lanceolate-triangular incurved or unci¬ 
nate lobules, obtusely 3-lobulate at the apex, the central tooth 
longest. Disc excavated in the center by a pair of elliptical 
depressions separated by a broad fleshy ridge and bounded 
in front by a fleshy 3-lobulate callus which is coincident 
with and near the 3-lobulate apex. Column stout, minute. 
Malaxis uncinata was described from dried specimens. 
In habit it resembles many of the subumbellate species of 
the genus. Florally it differs from the closely allied M. 
hastilabia (Reichb. f.) 0. Ktze. and from M. Maxonii Ames 
in the peculiar uncinate lobules at the base of the lip.
