ovate, 8 to 12 cm long, 3.5 to 6 cm wide, apex rounded to shortly 
and obtusely acuminate, below generally narrowed to the acute 
or cuneate base, the margins entire or very obscurely and dis- 
tantly crenulate-dentate ; lateral nerves 6 or 7 on each side 
of the midrib, prominent, more or less ascending, anastomosing, 
the reticulations lax; petioles stout, about 1 cm long. Fruits 
axillary and in the axils of fallen leaves, solitary or fascicled, 
or subspicately arranged on the very short axis, sessile, oblong, 
cylindric, 3-celled, 1 cm long, smooth, the basal bracteoles broadly 
ovate, obtuse, 2.5 mm long, glabrous; calyx-lobes crowning the 
fruit three, ovate, obtuse, 1.5 to 2 mm long.

between 250 and 400 meters. 
A most characteristic species, readily distinguished by being entirely 
glabrous, and by its obovate or narrowly obovate leaves; its numerous, 
sessile, oblong, cylindric fruits; and its 3-merous calyx, the latter a char- 
acter apparently new, or at least very rare, in the genus. 
SYMPLOCOS TRISEPALA sp. nov. § Babua, Lpdhra. 
Arbor parva, partibus junioribus et foliis subtus ad costa par- 
cissime longe ciliatis exceptis glabra; foliis oblongo-ellipticis ad 
oblongo-ovatis, coriaceis, usque ad 10 cm longis, acuminatis, basi 
obtusis, margine distanter glanduloso-denticulatis, nervis utrin- 
que circiter 7, subtus perspicuis ; spicis axillaribus, glabris, dense 
paucifloris, 1 ad 1.5 cm longis; calycibus tubo brevissimo, lobis 
3, ovatis, obtusis, circiter 3 mm longis. 
A small tree, entirely glabrous except for the widely scattered, 
long, ciliate hairs on the very youngest parts, petioles, and 
midribs on the lower surface of the leaves, perhaps ultimately 
entirely glabrous. Branches terete, reddish-brown, the branch- 
lets greenish-olivaceous, somewhat compressed. Leaves oblong- 
ovate to oblong-elliptic, coriaceous, 7 to 10 cm long, 3 to 4.5 
cm wide, yellowish-green when dry, shining, the apex distinctly 
and rather sharply acuminate, base obtuse, margins distantly 
glandular-denticulate, the gland-like teeth small, black when dry ; 
lateral nerves 7 on each side of the midrib, very prominent on the 
lower surface, anastomosing, the reticulations lax, prominent, the 
midrib impressed on the upper surface ; petioles 2 to 2.5 cm long. 
Spikes axillary, solitary, glabrous, 1 to 1.5 cm long, the flowers 
rather few, densely arranged, the subtending bracteoles ovate to 
elliptic-ovate, obtuse, coriaceous, 3 to 4 mm long, their margins 
glandular-denticulate. Flowers white or somewhat yellowish. 
Calyx-tube 1.5 mm long, the lobes 3, broadly ovate, obtuse, about 
3 mm long. Petals 5, broadly ovate to elliptic-ovate, 3.5 to 4
