Plant erect or curved, 50 cm or more long. Roots stout, 
greatly elongated, piercing the leaf sheaths of the lower part of 
the stem, up to 45 cm long. Stems rigid, about 1 cm in diameter, 
terete, somewhat flattened toward the apex, concealed by tubu¬ 
lar leaf sheaths; internodes 2 to 3.5 cm apart. Leaves distichous, 
oblong, 9 to 11.5 cm long, 3 to 3.7 cm wide, leathery, thick, flat, 
spreading, pale yellowish green, equally or unequally bilobed at 
the broad apex. Racemes rather stout, ascending, 3- or 4-

cm in length. Flowers large, about 4 cm across, very lax, fleshy, 
fragrant, lasting for a month or longer. Floral bracts deeply 
clasping or amplexicaul, triangular-ovate, apiculate, dorsally 
carinate, 7 to 10 mm long. Pedicellate ovary trigonous, mar¬ 
guerite yellow, about 2 cm long. Lateral sepals elliptic, 2.5 to 
2.8 cm long, 1.1 to 1.3 cm wide at the widest portion, subacute, 
at the very tip with a dorsal horn, which is 4 mm long. Dorsal 
sepal similar. Petals oblanceolate, 2.3 to 2.5 cm long, 0.8 to 
0.9 cm wide, subacute, with a horn at the very tip. Labellum 
about 1.9 cm long, fleshy, 5-lobed, base deeply concave; the basal 
lobes broadly rounded, auriculate, bluntly angled in front, erect, 
about 4 mm long, deeply connate with the sides of the column; 
middle lobe 3-lobed with lobes at right angles; side lobes trian¬ 
gular-lanceolate, 7 to 8 mm long, subacute, erect-spreading; ter¬ 
minal lobe linear-triangular, strongly compressed laterally and 
keel-like (when viewed from the side, highest beyond the mid¬ 
dle), obtuse, about 9 mm long, 4 mm wide at the base. Disc 
with several pubescent lines at the base between the basal 
auricles. Column short and stout, about 8 mm long with a pair 
of linear or linear-triangular arms at the apex. Ovary semi-

80831 Quisumbing, May 26, 1930. The living plants were epi¬ 
phytes collected from the forests of Atimonan, Tayabas Prov¬ 
ince, Luzon. Sepals and petals barium yellow to citron yellow 
barred with cinnamon brown. The middle lobe of the labellum 
"white, the lateral lobes marguerite yellow and spotted at the 
base with coral red on top. Gynostemium barium yellow. 
While this species was originally described as a member of 
the genus Trichoglottis, it is certainly aberrant from the general 
conception of that group in its relatively elongate several-flow¬ 
ered inflorescences of large flowers and especially in its spurless 
labellum.
