gradually smaller and more separate above. Inflorescence 
nodding, loosely paniculate with three or four short lat- 
eral branches; branches apparently 4-flowered, with a 
rachis about 1 cm. long. Bracts semiamplexicaul, broadly 
ovate, concave, acute, those subtending the branches 
much larger than the floral bracts. Flowers small, 
‘‘mignonette and dark violet,’’ distinctly pedicelled. 
Dorsal sepal ovate-lanceolate, short-acuminate, 6.5-7 
mm. long, about 2.6 mm. wide when expanded, with 
revolute or recurved sides. Lateral sepals shorter and 
broader than the dorsal sepal, obliquely oblong-ovate, 
acute and apiculate, about 6 mm. long and 8 mm. wide. 
Petals obliquely linear, acute, slightly decurved, 6—-6.5 
mm. long, 0.9-1 mm. wide. Lip adnate to the column- 
foot, broadly obovate, retuse-truncate and apiculate at 
the apex, cuneate at the base, ecallose, with the upper 
margins on each side irregularly crenulate-erose, 6.5-6.9 
mm. in greatest length, 5.5-5.8 mm. wide near the mid- 
dle. Column short, stout, lightly arcuate, broadly winged 
especially above, concave in front, 3-toothed at the apex, 
about 4 mm. high at the back, extended into a short 
stout foot. Anther incumbent, semiovoid, 2-celled with 
each cell divided into two chambers. Pollinia 4, com- 
planate, with the outer ones smallest. Pedicel and ellip- 
soid ovary finely pubescent. 
This species, representing a genus hitherto unrecorded 
from Peru, seems to be allied to the Brazilian Orleanesia 
yauaperyensis Rodr. However, it differs from that spe- 
cies in having eight leaves instead of four, in having larger 
(especially broader) blades which are obtuse and bilobu- 
late, rather than acute. The flowers of this plant are also 
rather smaller than in the Brazilian species.
