apiculate, the margine entire, or in the upper part with minute 
teeth at the ends of the lateral veins, both surfaces shining, 
the upper olivaceous, the lower paler, in age becoming quite 
glabrous, when young with scattered, long, white, stiff, stinging 
hairs; basal nerves usually 5; lateral nerves above the basal 
ones 5 to 7 on each side of the midrib, slender, distinct; petioles 
2 to 3 cm long. Racemes slender, including the peduncles 20 cm 
long or more, the flowers few, scattered (not seen) ; pedicels 
thickened, 2 mm long, each with a bract and two lateral brac- 
teoles, the bract oblong-ovate, acute or obtuse, somewhat pubes- 
cent, 1.5 mm long, the bracteoles lanceolate, 1 mm long. Per- 
sistent calyx-segments of the female flowers 6 (or 5), lanceolate, 
acute, entire, 2 to 2.3 mm long, slightly hirsute, not accrescent. 
Young fruits 3-locellate, slightly hirsute.

The species grows on large trees in forests, and the stinging- hairs on 
the leaves are irritating to the skin. It is undoubtedly most closely 
allied to the Javan Tragia hirsuta Blume, but differs in many characters, 
notably in its leaves, when adult, being quite glabrous. The genus is new 
to the Philippines, the species described by Blanco as T. innocua and T. 
bracteata certainly not belonging in the genus.

Frutex, partibus junioribus inflorescentiisque exceptis glaber; 
foliis oblongis ad late oblongo-oblanceolatis, chartaceis, usque 
ad 11 cm longis, acuminatis, basi rotundatis, integris, nervis 
utrinque circiter 7 ; petiolo 0.5 ad 2 cm longo ; inflorescentiis 
axillaribus, pedunculatis, usque ad 6 cm longis, corymbosis, mul- 
tifloris; floribus s circiter 5 mm longis, atropurpureis, sepalis 
petalisque 5; antheris 3. 
A shrub 2 to 3 m high, glabrous except the younger parts 
and the inflorescence. Branches slender, terete, grayish, gla- 
brous, the growing branchlets rather densely hirsute with pale, 
short, appressed hairs, the same type of indumentum on the 
young petioles, very young leaves, and the inflorescence. Leaves 
dark-brown when dry, oblong to broadly oblong-oblanceolate, 6 
to 11 cm long, 2 to 4 cm wide, entire, narrowed upward to the 
rather sharply acuminate apex, base slightly narrowed, rounded ; 
lateral nerves about 7 on each side of the midrib, slender, dis- 
tinct, anastomosing, curved, the reticulations obscure, lax; pe- 
tioles 0.5 to 2 cm long. Inflorescences numerous, axillary, soli- 
tary, long-peduncled, corymbose, many flowered, up to 6 cm
