with the specimen collected by Cuming (no. 2141) preserved in the Her- 
barium of the British Museum of Natural History. This species should 
not be confused with Cestichis compressa which is a much larger plant 
with a larger lip. That C. compressa is very closely allied to C. Cumingit 
can not be denied, but for the present it seems wise to regard them 
specifically distinct.

OBERONIA Lindl. 
Oberonia benguetensis sp. nov. 
Folia ensiformia, acuta, ad basim imbricata. Pedunculus 
elongatus, multo folia excedens, multibracteatus. Bracteae cir- 
citer 2 mm longae, setaceae. Racemus gracilis. Flores flavidi, 
minuti, circiter 1 mm longi.’ Sepala lateralia ovato-lanceolata. 
Sepalum superius triangulum. Petaia linearia, attenuata. Lab- 
ellum ad basim rotundatum, oblongum, ad apicem bilobum; 
lobi minuti, valde separati. 
Roots fibrous. Plants diminutive, about 4 cm high to the tip 
of the tallest leaf, stem very short. eaves ensiform or some- 
what falcate, acute, the largest about 3 cm long and 4 mm across 
from edge to edge, fleshy. Peduncle up to 1 dm long, much 
longer than the leaves, beset with numerous, spreading, setaceous 
bracts 2 mm long. Raceme somewhat drooping, about 5 cm 
long, 5 mm in diameter at the base when in flower. Flowers 
yellowish, irregularly verticellate, minute, exceeding the bracts. 
Floral bracts linear-acute, about 2 mm long, margin minutely 
denticulate. Pedicel and ovary 2 mm long, smooth. Lateral 
sepals ovate-lanceolate, concave, about 1 mm long. Upper sepal 
triangular, subacute (half lanceolate). Petals linear-lanceolate, 
tapering gradually from the base to the subacute tip. Labellum 
rounded at the base, 1 mm long, from about the middle to the 
tip oblong, each distal angle produced into a diminutive blunt 
lobe, recalling, although vaguely, Oberonia similis Lindl. (which ° 
is, however, lobed at the base), lobes about 0.5 mm apart. 
Column minute. «
