VIII, c, 6 Ames: Notes on Philippine Orchids 439 
dilated above, 2.5-3 cm long. Peduncles to the tip of the ra- 
ceme 17-20 cm long, arising from near the summit of the stem, 
ascending, with about four tubular bracts 4-5 mm long. Raceme 
loosely flowered, about 1 dm long with scale-like bracts sub- 
tending the flow^ers. Pedicels and ovary 1 cm long, slender. 
Flowers yellow, somewhat triangular in the bud. Lateral sepals 
oblong-spathulate, obtuse, deflexed, 9 mm long, 4 mm wide, fleshy. 
Upper sepal elliptic-oblong, obtuse. Petals oblong, obtuse, 8 mm 
long, about 3 mm wide. Labellum fleshy, rigid, 4 mm long, 
affixed to the base of the column, 3-lobed, subtriangular seen 
from the side, the lateral lobes forming the rounded apex of the 
triangle; middle lobe minute, fleshy, erect or slightly inflexed, 
thickened and obscurely round-toothed at the apex, about 1.5 
mm long, lateral lobes rounded in front, fleshy but not so thick 
as the rest of the lip. At the apex the lip is divided dorsoven- 
trally by a rigid membrane into two shallow compartments ; on 
each side above the compartments a triangular fleshy pubescent 
callus is affixed to the lateral walls of the sac and these calli are 
connected by a ridge of elevated tissue which joins a longitudinal, 
abbreviated keel at the back, the distal end of which passes into 
the dividing wall of the apical compartments. Gynostemium 
fleshy, 3 mm long, produced into an elongated beak in front, 4 
mm long. 
Leyte, Dagami, C. A. Wenzel U, November 25, 1912, 
The distinct septum of the labellum appears to be suflficient to place 
Camarotis philippinenais in Sarcantkits. Vidal placed this species in Sar- 
cochiltts but the internal structure of the labellum indicates close relation- 
ship with Sarcanthus. 
The Sarcantkinae-Aerideae of Pfitzer constitutes a large and puzzling 
group of genera several of which may be merged or more liberally broken up 
as further studies are made on fresh or alcoholic material.
