Canoe Camp, 150 ft., and Camp I, 700 ft. 
A charming plant, allied to M. Warapusse, Schlecht., but the lip is neither reniform 
nor toothed, and the auricles are blunt and incurved. The foliage is described by Kloss as 
dark green and light green or purple-brown and reddish green, and the flowers as deep 
yellow and crimson, or green to yellow to dull crimson. The leaves show when dry a paler 
broad bar up the centre. In habit it somewhat resembles M. micrantha, Hook. fil., of 
the Malay Peninsula, and in the form of the flower M. calophylla, Reichb., of Siam. 
MICROSTYLIS ATRO-BRACHIATA, Ridl., sp. nov. 
Caulis 4 cm. longus. Folia 4, lanceolata, acuta, basi breviter cuneata, viridia, 
inequalia, obliqua, 5-nervia, marginibus crispis, 5 cm. longa, 1°5 em. lata vel 
minora, petiolo 14 cm. longo. Racemus gracilis, 28 cm. longus, ad medium nudus. 
Flores parvi, approximati. Bractee lanceolate, acuminate, angustissime, deflexæ, 
3 mm. longe vel minores. Pedicelli brevissimi, 1 mm. longi. Sepalum posticum 
oblongo-lanceolatum, obtusum, lateralia ovata, obtusa, latiora, 2 mm. longa. Petala 
lineari-oblonga, obtusa, angustiora. Labellwm hastatum, integrum, acutum, 2 mm. 
longum, auriculis triangularibus exeurvis. Colwnna cylindrica, erecta, longa, pallida, 
stelidiis magnis atro-viridibus oblongo-ellipticis deflexis. Anthera minuta, lanceo- 
lata, obtusa. Rostellum erectum, lanceolatum, obtusum, eequilongum, virescens. 
Camp Vla, 3100 ft. 
Allied to M. tubulosa, J. J. Sm., it is one iol a small group in which the column is 
unusually tall and slender, the stelidia deep blackish green and very conspicuous, the 
anther small, and the rostellum large and nearly or quite as tall. Except for the fact 
that there are species of the genus known which connect these long-columned species 
with the typical forms with the short column, one would certainly distinguish these 
generically. ‘The column and anther are pale yellow, or perhaps white, the stelidia of 
a deep blackish green, elliptic and rounded at the top, and hanging down; the rostellum, - 
long, conspicuous and narrow, is also a very remarkable feature.
