culatus. Discus lineis 3, nervisque purpureis, parallelis percur- 
sus. Gynostemium perbreve, in pedem elongatum extensum. 
An epiphyte 30 to 55 cm high. The stems flushed with 
purple; the lower part pseudobulbous, angled, much thickened, 
consisting of three internodes which are up to 4.5 cm long and 
5 to 7 mm in diameter; the upper part terete, 1.5 to 2 mm 
in diameter. The leaf sheaths cylindrical, as long as the inter¬ 
nodes. Leaves terete, acicular or subulate, acute, 5.5 to 10.5 
cm long, 1.75 to 2.5 mm in diameter, ascending, glabrous, rather 
fleshy and rigid, flushed with brownish purple. Flowers odor¬ 
less, few, pale purple, appearing singly at the extremities of 
the stems. The bracts minute and very much shorter than the 
pedicellate ovary. Pedicellate ovary slender, about 7 mm long. 
Lateral sepals very broadly and obliquely triangular, acute, 
about 7 mm long, 7 mm wide along the column-foot, 3- to 5- 
nerved, forming an obtuse spur. Dorsal sepal triangular- 
lanceolate, acute, about 6.5 mm long, 3 mm wide at the base, 
5-nerved. Petals narrowly elliptic, obtuse, about 6.5 mm long, 
1.75 mm wide, 1-nerved. Labellum gradually cuneate at the 
base, dilated somewhat at the apex, lightly trilobed beyond the 
middle, about 12 mm long; lateral lobes subrounded, denticu¬ 
late, about 1.5 mm wide across the apex; middle lobe subqua¬ 
drate, denticulate, the apex very broadly rounded and apiculate, 
about 2.5 mm long, 3.5 mm wide. Disc traversed by three dis¬ 
tinct parallel lines, which are conspicuously purple. The column 
very short, tridentate at the apex, extended into an elongate foot.

Brown, December 24, 1929. Living plants were collected by 
Dr. William H. Brown, director of the Bureau of Science, Ma¬ 
nila, during a trip to Coron Island, while en route to Culion 
Leper Colony, situated on Culion Island, Palawan Province. 
These plants were found growing as an epiphyte on small trees 
on cliffs along the shore, and are now being cultivated in the 
Bureau of Science orchid house. 
Dendrobium modestum Reichb. f. has heretofore escaped all 
modern collectors. However, a record in the herbarium of 
Oakes Ames shows a sketch from the herbarium of Reichen- 
bach that represents unmistakably a species similar to the one 
from Coron Island. A minor discrepancy appears in the short, 
scarcely uncinate lateral teeth of the column.
