to 6 cm wide, narrowed above to the rather prominently acum- 
inate apex, the acumen blunt, the base broadly rounded, often 
slightly inequilateral, margins distantly crenulate-serrulate in 
the upper two-thirds, the basal part entire, of about the same 
color on both surfaces when dry, rather pale, not shining; 
lateral nerves about 7 on each side of the midrib, slender, obscure 
or subobsolete, the reticulations obsolete. Tendrils slender, 7 
cm long or less. Inflorescence axillary, solitary, 5 to 7 cm long, 
rather narrow, the primary branches 1.5 cm long or less. 
Flowers not known, apparently umbellate on the ultimate branch- 
lets. Fruit, very immature, ellipsoid to obovoid, very fleshy, 
5 to 8 mm long (apparently larger when mature), crowned by 
the remains of the style.

A species, although known from imperfect material, young fruits only 
being available, manifestly belonging in this genus. It is well characterized 
by its unifoliolate leaves, the single leaflets very greatly resembling the 
leaflets of a number of species of Tetrastigma. It was at first thought 
that the present species was referable to Tetrastigma, but the remains 
of the style and stigma on the young fruits shows no indications of the 
Tetrastigma-character, being quite entire.

This species is known to the Tagalogs as ayo or ayu, and is the one 
described by Blanco as Vitis pedata FI. Filip. (1837) 71, ed. 2 (1845) 52 
(non Linn.). The fruits are globose, russet-brown when mature, the pulp 
colorless or cream-colored, very juicy, acid or nearly tasteless, edible, and 
are eaten by the natives with fish. According to Mr. Borden’s notes the 
fleshy leaves are also eaten by the natives.
