brown when dry, coriaceous; its lax, long-peduncled panicles; and its 
apiculate petals. It appears to be allied to Tetrastigma brunneum Merr., 
but has entirely different male flowers. 
A third species with its leaves consistently dark brown when dry is 
represented by fruiting specimens from Benguet Subprovince, Elmer 5976, 
with immature fruits, and Bur. Sci. 13512 Ramos, with mature fruits. 
It may prove to be the same as the species just described, but it appears 
to be different, and has 3- to 5-foliolate leaves. 
TETRASTIGMA LITTORALE sp. nov. 
Frutex scandens inflorescentiis exceptis glaber, ramis tere- 
tibus; foliis pedatim 7-foliolatis, foliolis ellipticis vel ovato- 
ellipticis, coriaceis, usque ad 15 cm longis, in siccitate pallidis, 
abrupte brevissime acuminatis, basi acutis vel rotundatis, nervis 
utrinque 5 vel 6 ; inflorescentiis axillaribus, leviter pubescentibus, 
3- vel 4-pinnatim umbellato-corymbosis ; floribus 4-meris, pe- 
talis oblongo-ovatis, acutis, vix corniculatis, supra extus parce 
pubescentibus; ovario glabro. 
A vine 10 to 15 m in length, glabrous except the inflorescence, 
the branches brownish, terete, more or less lenticellate. Leaves 
pedately 7-foliolate, the petioles stout, 5 to 6 cm long, the middle 
leaflet larger than the lateral ones, its petiolule 3 to 4 cm long, 
the common petiolule of the three lateral leaflets 1.5 to 2.5 cm 
in length, the petiolules proper 5 to 15 mm long; leaflets sub- 
coriaceous or coriaceous, rather pale when dry, of the same 
color on both surfaces and dull or slightly shining, elliptic to 
ovate-elliptic, 8 to 15 cm long, 4.5 to 9 cm wide, the middle one 
larger than the others which gradually decrease in size out- 
ward, abruptly and shortly acumnate, the base acute or 
rounded, of the lateral ones somewhat inequilateral, the margin 
more or less recurved, distantly and irregularly serrate-crenate ; 
nerves 5 or 6 on each side of the midrib, curved, the reticu- 
lations lax, obscure. Inflorescence axillary, peduncled, solitary, 
about as long as the petioles, sparingly pubescent with scattered 
hairs, the peduncle 1.5 to 2 cm long, bearing about 4 umbellately 
arranged primary branches of about the same length as the 
peduncle, these again umbellately branched, the ultimate branch- 
lets with from 10 to 15 umbellately arranged flowers, their 
pedicels pubescent, 3 to 4 mm long. Pistillate flowers greenish- 
white, 4-merous. Calyx very obscurely and broadly lobed, or 
truncate. Petals 4, oblong-ovate, acute, 2.5 to 2.8 mm long, 
free, reflexed in anthesis, neither cucullate nor spurred, below 
glabrous, near the apex sparingly pubescent. Staminodes 
slender, 1.5 mm long. Ovary ovoid, glabrous, more or less nar- 
rowed upward but not attenuate, about 1.5 mm long; stigma
