LAPORTEA TRIPLINERVIA sp. nov. 



Arbor parva, subtus foliis pilis longis sparsis urentibus in- 

 structis; 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. 19^62 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- 

 ing, the lower brownish, dull; lateral nerves prominent, about 

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