TROPICAL AMERICAN ORCHIDS 
Dichaea verrucosa cS: S. sp. nov. Caules penduli, 
dense distichifolii. Folia parva, oblongo-elliptica, patentia. 
Flores singuli ut videtur, breviter pedicellati, pro herba 
grandes. Sepala petalaque similia, lanceolato-ovata, valde 
concava, dorso subdense muricata. Labellum late rhombi- 
cum, ancoraeforme, apiculatum vel acutum, medio utrin- 
que cum lobulo lineari retrorso. Columna brevis, cum lig- 
ula infrastigmatica lineari. 
Stems exceeding 13.2 cm. in length (incomplete in our 
specimens, but apparently long and pendulous), densely 
leaved, entirely concealed by imbricating leaf-sheaths. 
Leaves very numerous, distichous, not articulated; blades 
spreading, elliptic or oblong-elliptic, 9 (rarely 8)-12.5 mm. 
long, 4-6 mm. wide, apically rounded with a caducous api- 
cule. Peduncle short, 1-flowered, subequaling the leaves, 
axillary, filiform, spreading. Floral bracts minute, two in 
number; one shallowly infundibuliform, membranaceous and 
abruptly apiculate; the other within the first, rigid, obliquely 
ligulate and acuminate. Ovary short, densely papillose- 
muricate with longer papillae above, enveloped by the outer 
bract. Flower large for the plant; perianth segments con- 
nivent, rather fleshy. Sepals and central part of petals sub- 
densely muricate without, all concave. Lateral sepals lanceo¬ 
late-ovate, 9.1-10.6 mm. long, 3.9-5.8 mm. wide, acumi¬ 
nate, subcarinate above, 7-nerved (indistinctly 8-nerved), 
lightly oblique. Dorsal sepal 10-11.9 mm. long, about 
5 mm. wide below, 9-nerved, similar to the lateral sepals. 
Petals similar to the sepals, 8.6-10.9 mm. long, 4.2-4.9 mm. 
wide, dorsally carinate at the apex, lightly oblique, 7-nerved 
with a faint short outer nerve on each side. Labellum broadly 
rhombic in outline, anchor-shaped, concave, 7.1-8 mm. long 
including the short quadrate claw, basal margins rounded 
and densely long-ciliate; lamina abruptly dilated into a pair 
of linear-lanceolate retrorse obtuse lobules which are about 
2.5 mm. long, anterior portion in natural position rounded 
and apiculate (by reason of the incurved sides),—when ex¬ 
panded rounded-triangular and acute,—11-12-nerved. Col¬ 
umn very short, with a conspicuous ligulate pubescent infras- 
tigmatic appendage.
