riaceous, when dry of about the same color on both surfaces, 

 pale or brownish, dull or slightly shining, margins distantly 

 serrate, the teeth mostly small; nerves about 8 on each side of 

 the midrib, the reticulations obscure; petiolules of the lateral 

 leaflets 8 to 10 mm long, of the middle one 2.5 to 4 cm long. 

 Inflorescence axillary, dense, many-flowered, ferruginous or 

 brownish-pubescent, 3 cm long or less, the peduncles usually 

 about 1 cm long, umbellately branched. Female flowers 4- 

 merous, their pedicels short. Calyx shallowly cup-shaped, 1.2 

 mm in diameter, very obscurely 4-toothed. Petals oblong, 

 obtuse, cucullate, not at all corniculate, uniformly pubescent 

 externally, about 2 mm long. Staminodes slender, dilated at the 

 apex, about 1 mm long. Ovary cylindric-ovoid, uniformly pu- 

 bescent; stigma sessile, distinctly 4-lobed, about 1 mm in dia- 

 meter. Male flowers similar, shorter, 4- or 5-merous, the anthers 

 1 mm long. Fruit not seen. 



Mindanao, Lake Lanao, Camp Keithley, Mrs. Clemens s. n., November, 

 1906 (type) ; also from the same locality, No. 85, January, 1906, s. n., 

 January, 1907. A specimen with male flowers, November, 1906, is probably 

 the same; this has its leaves 3-foliolate and 1-foliolate on the same 

 branchlet. 



A species well characterized by its pubescent petals and ovaries, its 

 3-foliolate leaves with elliptic leaflets, and its very unequal petiolules, that 

 of the middle leaflet being very much longer than those of the lateral 

 ones. The dense inflorescense which is uniformly brownish or ferruginous- 

 pubescent is also characteristic. 



TETRASTIGMA ELLIPTICUM sp. nov. 



Frutex scandens, glaber; foliis 3-foliolatis, foliolis ellipticis, 

 coriaceis, in siccitate brunneis, usque ad 13 cm longis, apice acu- 

 minatis apiculatisque, base subrotundatis ad subacutis, margine 

 distanter serrulatis; inflorescentiis amplis, ut videtur laxis, cir- 

 citer 20 cm longis; fructibus anguste obovoideis, circiter 1 cm 

 longis. 



A scandent glabrous vine, the branches rather slender, terete, 

 lenticellate, dark-colored when dry. Leaves 3-foliolate, the pet- 

 ioles 4 to 5 cm long, the rachis produced about 3 cm above the 

 insertion of the lateral leaflets ; leaflets 3, elliptic, sometimes ellip- 

 tic-ovate, coriaceous, the smaller ones 6 cm long and 4 cm wide, 

 the larger up to 13 cm long and 7 cm wide, brown when dry, 

 slightly shining, the lower surface a little paler than the upper, 

 the apex prominently and rather slenderly acuminate, the acumen 

 apiculate, base somewhat rounded on subacute, margins distantly 

 denticulate; lateral nerves about 8 on each side of the midrib,
