Tetrastigma brunneum sp. nov. 
Frutex scandens, glaber, ramulis teretibus; foliis palmato 3- 
ad 5-foliolatis, foliolis coriaceis, in siccitate brunneis, ovatis, 
oblongo-ovatis, vel subellipticis, basi acutis vel rotundatis, apice 
abrupte subtenuiter acute acuminatis apiculatisque, margine 
distanter crenato-serratis ; inflorescentiis axillaribus, laxis, 
corymboso-paniculatis ; floribus 4-meris, subumbellato dispositis, 
circiter 1.5 mm longis, numerosis; fructibus obovoideis vel

rugosis, baud sulcatis. 
A woody vine 5 to 6 m in length, glabrous throughout. Stems 
and branches terete, light-brown, striate, the branchlets usually 
smooth, black or dark-colored when dry. Tendrils leaf-opposed, 
forked, up to 18 cm in length. Leaves palmately 3- to 5-folio- 
late, their petioles 1.5 to 5 cm in length. Leaflets ovate, oblong- 
ovate, or subelliptic, firmly coriaceous, always brown when dry, 
the lower surface a little paler than the upper one, slightly 
shining, 5 to 10 cm long, 2 to 5 cm wide, the middle leaflet 
larger than the lateral ones, abruptly and rather slenderly 
acutely acuminate, the acumen apiculate, the base rounded or 
acute, the margin distantly crenate-serrate, the teeth usually 
rather prominent, often apiculate; nerves 5 or 6 on each side 
of the midrib, not prominent, anastomosing, the reticulations 
lax, obscure; petiolules of the lateral leaflets 4 to 8 mm long, 
that of the middle one about 1.5 cm in length. Inflorescence 
axillary, rather lax, corymbose-paniculate, many-flowered, 
peduncled, about 8 cm long, enlarged in fruit and often forming 
terminal or subterminal more or less leafy panicles. Male 
flowers : Calyx shallowly cup-shaped, truncate, about 1 mm in 
diameter. Petals 4, free, oblong, 1.8 to 2 mm long, obtuse, 
cucullate at the apex inside. Filaments about 1 mm long, 
inserted under the broad disk; anthers 0.5 mm long, broader 
than long. Disk prominent, obscurely 4-angled or lobed. Female 
flowers: Calyx somewhat funnel-shaped, truncate, 1.2 mm in 
diameter. Petals as in the males. Staminodes slender, 1 mm 
long, slightly dilated at the apex. Ovary cylindric-ovoid, 
truncate, glabrous, 1.2 mm long; stigma sessile, disk-like, not 
at all or very obscurely lobed, 0.7 mm in diameter. Fruit 
obovoid to oblong-obovoid, about 8 mm long, apparently some- 
what fleshy, each containing two plano-convex seeds, or the
