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-floweTed, 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,
