shorter than the sepals; rudimentary ovary none. Pistillate 
flowers and fruits unknown. 
Luzon, Ilocos Norte Province, Burgos, Bur. Sci. 32854- Ramos, 
July 26, 1918, in dry forests at low altitudes. 
This species is entirely different from the other two known 
from the Philippines and probably belongs in the alliance with 
Tragia involuc7'ata Linn. It is well characterized by its oblong, 
somewhat undulate leaves, which are rounded, slightly cordate, 
and minutely peltate at the base, and by its spicately arranged 
staminate flowers. In this genus the pistillate flowers are 
usually found at the base of the staminate inflorescences; but 
none of the specimens of Tragia luzoniensis shows any indication 
whatever of pistillate flowers, so that apparently the present 
species is dioecious. The stinging hairs of the present species 
are very short and are apparently confined to the lower surface 
of the leaves. 
TRAGIA PHILIPPINENSIS sp. nov. 
Scandens, ramulis, foliis et fructibus pilis numerosis urenti- 
bus instructis ; foliis oblongo-ovatis ad oblongo-lanceolatis, usque 
ad 10 cm longis, basi late truncato-subcordatis, leviter hastatis, 
sursum gradatim angustatis, tenuiter acute acuminatis; sepalis 
9 3, accrescentibus, subcoriaceis, ovatis, circiter 10 mm longis, 
obtusis ad leviter acuminatis, integris; coccis circiter 7 mm 
diametro, perspicue hispidis, pilis urentibus. 
A scandent, herbaceous or subherbaceous vine, the branchlets, 
leaves, and other parts prominently hispid with scattered, white, 
stiff, stinging hairs 2 to 3 mm in length. Leaves membrana- 
ceous, oblong-ovate to oblong-lanceolate, 7 to 10 cm long, 2.5 
to 4 cm wide at the truncate-subcordate and slightly hastate 
base, gradually narrowed upward to the slenderly and sharply 
acuminate apex, often with 2 or 3 coarse teeth or shallow lobes 
on each side near the base, otherwise entire, both surfaces with 
scattered, stiff, stinging hairs, the upper surface brown or cas- 
taneous when dry, the lower greenish; lateral nerves 4 or 5 
on each side of the midrib, prominent, anastomosing; petioles 
about 3 cm long. Staminate flowers 3-merous, the buds trian- 
gular, the sepals reniform-ovate, about 3 mm long and 4 mm 
wide. Disk much thickened; stamens 3, about 2 mm long. 
Pistillate sepals in fruit 3, subcoriaceous, spreading, entire, 
ovate, obtuse to somewhat acuminate, about 10 mm long and 7 
mm wide. Fruits depressed, about 12 mm in diameter, brown.
