temium crassum, perbreve, superne tridentatum, in pedem elon- 
gatum extensum. 
Stems rather tall, branching sparingly near the top, up to 
115 cm long, pseudobulbous at base; lower part 5 to 15 cm long, 
fusiform, enlarged at the middle and tapering at both ends, con- 
spicously ridged, 1.5 to 2.5 cm in diameter with 3 internodes 
1.5 to 3.5 cm long; upper part slender, terete, 2 to 3 mm in 
diameter, greenish olive or reddish brown. Leaves subterete, 
channelled, filiform, subulate, 8 to 16 cm long, 1.5 to 2.5 mm 
in diameter, dark green. Flowers produced singly from tufts 
of bracts along the naked termination of the stems or from the 
axils of upper leaves, 3.5 to 4 cm long, 3 to 4 cm across. The 
bracts small, hyaline. Pedicellate ovary 1.6 to 1.8 cm long. 
Lateral sepals very broadly triangular, very oblique, as long as 
the dorsal sepal, forming with the column-foot a spur that is 
stout, rather recurved, obtuse, 1.8 to 2 cm long. Dorsal sepal 
triangular-lanceolate or ovate-lanceolate, acute, 1.5 to 1.8 cm 
long, 0.9 cm wide, 5- to 7-nerved. Petals ovate-lanceolate acute, 
about 1.4 cm long, 0.6 cm wide, 3- to 7-nerved. Labellum tri- 
lobed near the apex, cuneate at the base, obovate, 2.3 to 2.5 cm 
long; lateral lobes broadly triangular; the middle lobe larger 
than the lateral lobes, semiorbicular, notched at the apex, crisped, 
the margins minutely crenulate, papillose. Disc through the 
basal part lightly tricarinate, the keels produced in front into 
a single fleshy band. Column very short and stout with three 
teeth at the apex, extended into an elongated foot.

79065 Quisumbing, May 24, 1930, the living plants being orig¬ 
inally collected at Atimonan, Tayabas Province. 
The flowers open one at a time on the nodes along the naked 
termination of the stems or in the axils of apical leaves and 
are very fragrant, the odor approaching that of Dendrobium 
crumenatum Sw. In habit the flowers differ from those of D. 
crumenatum Sw. in that they remain fresh on the plant for 
several days. The sepals, petals, spur, and pedicellate ovary are 
chartreuse yellow with some cream color at the apices of the 
petals and sepals. The lateral lobes of the labellum including 
the cuneate base are white, the reticulations are dark rhoda- 
mine purple or true purple, the middle lobe of the labellum and 
the disc are chartreuse yellow. The plants first flowered in 
the Bureau of Science orchid house June 1, 1929, and again May 
24, 1930.
