NKW 0]\ NOTEWORTHY ORCHIDS 
at the base and abruptly contracted, jointed to more or less 
complanate sheaths which are 5-10 mm. long. Peduncle 
commonly terminal, rarely terminal and lateral, simple or 
sometimes branched at the base, including the raceme up 
to 8 cm. long, elongating during the flowering period, the 
sterile or flowerless part shorter than the subtending leaf. 
Raceme many-flowered, slender, with a slightly zig-zag 
rachis. Bracts of the raceme 3-4 mm. long, with the 
margin more or less hyaline, strongly concave, ovate, acute, 
widely spreading, equaling the ovary during anthesis. 
Flowers white with a white and purple labellum. Lateral 
sepals 3 mm. long, forming a blunt mentum, 3 mm. wide 
to the tip of the mentum, broadly triangular, obtuse or sub¬ 
acute, 3-nerved, with the mid-nerve slightly prominent. 
Dorsal sepal 3 mm. long, strongly concave, elliptic-ovate, 
obtuse. Petals about 3 mm. long, 2 mm. wide across the 
tip, gradually narrowed toward the base, oblong-spatulate 
or cuneate-spatulate, truncate at the tip or obscurely and 
bluntly 3-lobed. Labellum 4 mm. long, about 3 mm. wide 
across the tip, subpandurate, truncate, 7-ncrved. Disc pro¬ 
vided near the base with a conspicuous U-shaped callus 
which is 1 mm. high at the base, its sides intramarginal 
and about 2 mm. long. Column 2 mm. long, prolonged into 
a conspicuous foot which is 2.5 mm. long; rostellum with a 
U-shaped incisure at the tip. 
Closely allied to Appendicula xytriophora Reichb. f., 
from which it differs conspicuously in the shape of the 
petals and labellum, and in the tendency to produce simple 
stems. In A. xytriophora the petals tend to be oblong rather 
than cuneate-spatulate, and are about as broad at the tip as 
at the base, while the labellum is not conspicuously wider 
at the tip than at the base. [Fig. 9, habit and flower.] 
Philippines, Leyte, C. A. Wenzel 0635, November 11, 
1914. Epiphyte in forest. 600 meters altitude. (Type in 
Llerb. Ames No. 26651): Wenzel 0702, November 23, 1914. 
600 meters altitude: Wenzel 0685, November 20, 1914: 
Wenzel 0668, November 15, 1914. 600 meters altitude. On 
the evidence of other specimens examined this species would 
seem to be a native of Luzon, Mindanao and Samar.
