Alyxia monticola .sp. now 
Scandens, Alyxiae luzoniensi ^Merr. adniodum similis, sed differt foliis 
majoribus longius pctiolatis magis acuminatis ma^s conspicue venosis^ 
et ram is crassioribus. 
Cymes axillary, few-flowered : flowers unknown : peduncles stout, about 
1 cm long, brown-tomentose ; pedicels strongly 4-angled, 3 mm long, 2 
mm wide, tomcntose; bracts at base of calyx 2, ovate, obtuse, 3 mm long; 
calyx deeply 5-parted, the segments similar to the bracts but slightly 
longer, pubescent on the costa and margins; stipe of fniit 6 mm long, 
pubescent, the fruits oval in outline, not constricted, up to 22 mm long, 
12 mm in diameter. 
A woody vine, the branches about 5 mm in diameter at the base, the 
bark drying yellowish-green to dark-brown, the vegetative parts glabrous: 
leaves in whorls of 4 or 5; petioles 8 to 10 mm long, 1.5 to 2 mm wide; 
lamina subcoriaceous, oblong or oblong-oblaneeolate, 8.5 to 14.5 cm long, 
2.5 to 4.8 cm wide, the base acute and decurrent, the margins slightly 
revolute, the apex abruptly contracted into an obtuse or subacute acumen 
8 to 12 mm long; pairs of veins about 50, nearly straight, terminating 
in a slender lateral vein about 1 mm from the margin, the lamina espe- 
cially when viewed from the upper surface appearing distinctly margined. 
ZON, Province of Tayabas (Infanta), Mount Binuang, in mossy forest at 
840 m elevation. Bur. Sci. 9S60 Robinson. The nearest alliance of the species 
seems to be with A. luzoniensis Merr., but it differs by the characters noted 
above. The leaves more nearly resemble those of A. monilifera Vidal, but the 
structure of the fruit is conspicuously different, not constricted, and the size of 
it3 single compartment much greater than that of those of A. monilifera.
