LAPORTEA TRIPLINERVIA sp. nov. 
Arbor parva, subtus foliis pilis longis sparsis urentibus in- 
structs ; foliis oblongis, chartaceis vel membranaceis, usque ad 
18 cm longis, in siccitate viridis, utrinque subaequaliter angus- 
tatis, basi acutis, triplinerviis, apice acuminatis, nervis utrinque 
circiter 6 ; infructescentiis axillaribus, usque ad 6 cm longis, fruc- 
tibus in siccitate nigris, capitulis globosis, 8 ad 10 mm diametro, 
acheniis numerosis. 
A tree up to 13 m in height, the leaves with persistent, long, 
stiff, scattered, stinging hairs on the lower surface. Branches 
pale gray, terete, 4 to 6 mm in diameter. Leaves green when 
dry, in general oblong, chartaceous or membranaceous, 10 to 
18 cm long, 3 to 6.5 cm wide, entire, subequally narrowed 
to the acute, 3-plinerved base and to the acuminate apex, the 
upper surface rather densely white-puncticulate ; lateral nerves 
about 6 on each side of the midrib, rather prominent, curved; 
petioles 2 to 4 cm long. Infructescences axillary, up to 6 cm 
long, with few branches, the achenes arranged in dense globose 
heads at the tips of the branchlets, up to 15 or more achenes in 
each head, the heads black when dry, 8 to 10 mm in diameter. 
Luzon, Province of Tayabas, Mount Pular, Bur. Sci. 19 462 Ramos, 
January 15, 1913, on forested slopes. 
A species somewhat resembling Laportea luzonensis Warb., but with the 
leaves constantly acute and 3-plinerved at the base, the stinging hairs 
persistent on the lower surface, which sting even when dry, and with 
an entirely different arrangement of its fruits, the achenes crowded into 
dense, globose heads which are black when dry, not flabellately arranged.

HELICIA LONGIFLORA sp. nov. 
Arbor parva, circiter 8 m alta, glabra; foliis late oblongo- 
oblanceolatis, integris, usque ad 15 cm longis, breviter obtuse 
acuminatis, basi acutis ; racemis folia subaequantibus, paucifloris, 
pedicellis in paribus connatis ; floribus 2.5 cm longis. 
A small tree, quite glabrous, or the racemes with few, scattered, 
deciduous hairs, the branches rather stout, terete, brownish. 
Leaves subcoriaceous, broadly oblong-oblanceolate, 11 to 15 cm 
long, 3.5 to 5.5 cm wide, entire, the apex rather shortly and 
obtusely acuminate, sometimes falcate, the base gradually nar- 
rowed to the short stout petiole, cuneate and sometimes a little 
decurrent, upper surface olivaceous when dry, somewhat shin-

10 on each side of the midrib, curved-ascending; petioles 5 to 8
