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 f ertilibus 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 U5U, 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.
