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,

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.
