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 

 Tetrostifirma-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 PI. 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.
