Apparently closely allied to Tetrastigma lanaceolarium Planch., but 

 distinguished by its 7-foliolate leaves, and its very differently shaped, 

 relatively broad leaflets.

Frutex scandens glaber; foliis pedatim 7-foliolatis, longe pe- 

 tiolatis, foliolis oblongis vel elliptico-oblongis, chartaceis, usque 

 ad 18 cm longis, subcaudato-acuminatis, margine grosse irreg- 

 ulariter sinuato-serratis vel serrato-lobatis, nervis utrinque 12 

 ad 15, distinctis; inflorescentiis oppositifoliis, amplis, usque ad 

 15 cm longis, laxis, subumbellato-cymosis ; fructibus immaturis 

 obovoideis, 6 mm longis. 



A large, coarse, scandent vine, quite glabrous, the branches 

 terete, striate when dry, usually olivaceous, sparingly lenticel- 

 late. Tendrils 20 to 30 cm in length. Leaves large, pedately 

 7-foliolate, their petioles stout, 8 to 12 cm long; leaflets char- 

 taceous, brownish-olivaceous when dry, shining, oblong to elliptic- 

 oblong, 10 to 18 cm long, 4 to 7 cm wide, the middle one usually 

 somewhat larger than the outermost lateral ones, base acute, 

 apex rather shortly, abruptly, subcaudate acuminate, margins 

 very coarsely and irregularly sinuate-serrate or serrate-lobed, 

 the teeth sharp ; nerves rather prominent on the lower surface, 

 12 to 15 on each side of the midrib; petiolule of the middle 

 leaflet up to 5 cm long, the common ones of the 3 lateral leaflets 

 about 3 cm long, their petiolules proper 1 to 1.5 cm long, of 

 the outermost shorter than the inner ones. Inflorescence leaf- 

 opposed, lax, ample, about 15 cm long, peduncled, at first dichoto- 

 mously branched, then umbellately branched, the flowers umbel- 

 lately arranged on the ultimate branchlets. Flowers 4-merous. 

 Calyx truncate. Petals not seen. Ovary ovoid, glabrous, the 

 stigma sessile, distinctly 4-lobed, the lobes about as long as wide. 

 Fruit immature, obovoid, about 8 mm long.

A species well characterized by its large, pedately 7-foliolate, long- 

 petioled leaves; its rather prominently nerved, very coarsely toothed leaves; 

 and its ample, lax inflorescence, which is about 15 cm in length and about 

 as wide as long.
