the midrib and, to a less degree, the reticulations prominently 
pubescent; petioles pubescent, about 3 mm long. Flowers 5- 
merous, in axillary fascicles, their pubescent pedicels about 2 
mm long. Sepals 5, elliptic, rounded, pubescent, 2 to 2.5 mm 
long. Fertile stamens 10, glabrous, the alternating staminodes 
forming a very short tube, narrowly oblong, truncate, villous 
at the tip, 0.3 mm long. Ovary narrowly ovoid, densely villous, 
including the cylindric-capititate stigma about 1.7 mm long.

Manifestly in the group with Casearia grewiaefolia Vent., but with fewer 
lateral nerves. Above all easily distinguished by its numerous, minute, 
glandlike teeth. 
CASEARIA PUBESCENS sp. nov. 
Arbor, ramulis subtus foliis ad costa nervisque floribusque 
prominente pubescentibus ; foliis oblongis, integris, usque ad 20 
cm longis, chartaceis, abrupte acuminatis, basi aequilateralibus, 
rotundatis, breviter petiolatis, nervis utrinque 12, prominentibus ; 
floribus axillaribus, fasciculatis, breviter pedicellatis, 5-meris, 
staminibus fertilibus 10 ; ovario pubescente. 
A tree, the branchlets, flowers, and the lower surface of the 
leaves, especially on the midrib and lateral nerves, prominently 
pubescent with short, spreading, pale-brownish or somewhat 
tawny, rather soft hairs. Leaves oblong, chartaceous, brownish- 
olivaceous when dry, dull or slightly shining, 11 to 20 cm long, 
5.5 to 8.5 cm wide, the apex rather abruptly acuminate, the acu- 
men 1 to 1.5 cm long, rather blunt, base equilateral, rounded, 
margins entire, the upper surface glabrous, or somewhat pubes- 
cent along the midrib; lateral nerves 12 on each side of the 
midrib, prominent, curved-ascending, scarcely anastomosing, the 
reticulations fine; petioles pubescent, stout, about 5 mm long. 
Fascicles axillary, the bracteoles very numerous, ovate, acute or 
acuminate, pubescent, about 1 mm long, forming a dense sub- 
globose mass up to 5 mm in diameter, but few flowers developing 
at one time. Pedicels pubescent, about 1 mm long. Buds sub- 
globose. Sepals 5, elliptic, concave, rounded, densely pubescent, 
in bud about 2 mm long. Fertile stamens 10. Ovary ovoid, 
rather densely pubescent with cinereous or pale hairs, the style 
very short. 
Sarawak, Baram District, Entoyut River, Hose b5b, November, 1894. 
Apparently as closely allied to Casearia philippinensis Merr. as any 
other species; readily distinguished, however, by its leaves not being 
gradually narrowed upward but abruptly acuminate, rounded, not acute at 
the base, and its densely pubescent ovary. From C. lobbiana Turcz. it is 
distinguished by its more numerous lateral nerves and pubescent flowers.
