foliolis oblongo-ovatis, breviter acuminatis, chartaceis, usque ad 
18 cm longis, margine distanter denticulato-crenatis ; inflores- 
centiis axillaribus, pubescentibus bipinnatim umbellatis, quam 
petiolo brevioribus ; floribus 4-meris, petalis extus pubescentibus, 
oblongo-ovatis vel ovatis, obtusis, apice vix corniculatis, haud 
cucullatis; ovario glabro; stigmatibus sessilibus, 4-lobatis, lobis

A scandent shrub, glabrous except the inflorescence. Branches 
terete, striate, brownish-gray when dry, longitudinally striate, 
sparingly rugose with prominent lenticels. Tendrils simple, 
leaf-opposed, 15 cm long or longer. Leaves 3-foliolate, their 
petioles about 5 cm long ; leaflets oblong-ovate, chartaceous, 
rather pale when dry, of the same color and slightly shining or 
dull on both surfaces, 11 to 18 cm long, 4.5 to 10 cm wide, the 
apex shortly acuminate, the base acute or somewhat rounded, 
the margins distantly denticulate-crenate ; nerves 7 to 10 on each 
side of the midrib, distant, curved, not very prominent, the 
reticulations lax, obscure ; petiolule of the middle leaflet 3 to 3.5 
cm long, of the lateral ones about 1 cm long. Inflorescence 
axillary, peduncled, bipinnately umbellate, pubescent, about 4 cm 
long, the peduncles solitary or in pairs, 1.5 to 2 cm long, each 
bearing from 3 to 5 umbellately arranged primary branches 1 to 
1.5 cm in length, each primary branch bearing numerous, um- 
bellately arranged flowers, their pedicels 3 to 5 mm in length. 
Staminate flowers: Calyx disklike, truncate, about 1.5 mm in 
diameter. Petals 4, ovate to oblong-ovate, uniformly pubescent 
externally, 2.5 mm long, free, obtuse, not corniculate at the apex 
and but little cucullate. Staminodes about 1 mm long, slender, 
spatulate. Ovary ovoid or subglobose, glabrous, not attenuate, 
apex abruptly rounded, 1.5 mm long; stigma sessile, 4-lobed, 
the lobes spreading, short, about as long as wide. 
Polillo, Bur. Sci. 10400 McGregor, October 18, 1909, flowers pale 
yellow. 
Apparently most closely allied to Tetrastigma quadridens Pierre of 
Cochin China, but still very different from that species according to its 
description.
