NEW OR NOTEWORTHY ORCHIDS 
cronata, uninervia, in dorso carinata. Petala flabellato- 
spathulata, antice latissime rolundata. Labellum simplex, 
oblongo-lanceolatum, valdissime naviculare, acutum, in basi 
callo magno siibquadrato excavate ornatum. Golumna abbre- 
viata, rostello longissimo praedita. 
Epiphytic herb, 8 cm. high to the tip of the longest leaf. 
Roots fibrous, lanuginose, slender. Leaves equitant, ob¬ 
long-linear, more or less falcate, up to 6.1 cm. long, 5-7.5 
mm. wide near the middle, acute, gradually narrowed be¬ 
low, articulated to sheaths which are short complanate 
their upper edge with a broad scarious protruding margin. 
Inflorescence arcuate, shorter than or subequaling the leaves. 
Peduncle up to the raceme short, very narrowly winged, 
with several prominent spreading bracts. Raceme loosely 
few-flowered; rachis flexuous. Floral bracts lanceolate, acu¬ 
minate, carinate, minutely erose, spreading. Flowers up to 
8 in number, green and white. Lateral sepals broadly ob- 
ovate, 2.8 mm. long, or 3.8 mm. long including the prominent 
mucro, about 2 mm. wide, rounded and minutely erose at 
the apex, 1-nerved, dorsally carinate, somewhat oblique. 
Dorsal sepal very similar, cucullate. Petals spatulate- 
flabellate, 3.1-3.5 mm. long, about 3 mm. wide above, 
broadly rounded at the apex, minutely apiculate in the mid¬ 
dle, 1-nerved, the basal and anterior margins minutely erose. 
Labellum oblong-lanceolate, very strongly navicular and con¬ 
cave, about 4 mm. long in natural position with the anterior 
part upeurved, acute, dorsally keeled especially in the an¬ 
terior half, denticulate near the apex, 5-nerved. Disc at 
base with a large subquadrate excavated callus which is 
dilated toward its base. Column minute, extended into a 
very large elongate recurved rostellar process which sub¬ 
equals the labellum. Anther with an elongate channeled 
beak. Pollinia 4, pyriform-obovoid. 
Ornithocephalus Valerioi was described from a single 
dried specimen. It is apparently allied to 0. elephas Reichb. f., 
but it has differently formed lateral sepals and petals and a 
very large rostellar process.
