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 scan dens inflorescentiis exceptis glaber, ramis tere- 

 tibus; foliis pedatim 7-f oliolatis, . 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

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
