CYCLOSTEMON OLIGOPHLEBIUM sp. nov. 
Arbor glabra; foliis chartaceis, oblongo-ovatis ad ellipticis, 8 
ad 12 cm longis, integris, in siccitate pallide olivaceis, basi acu- 
tis ad rotundatis, equilateralibus vel leviter inaequilateralibus, 
apice tenuiter acuminatis, nervis utrinque circiter 5, perspicuis; 
floribus ¢ axillaribus, solitariis, breviter (2 mm) pedicellatis, 
sepalis late ovatis, rotundatis, 5 ad 6 mm longis, leviter pubes- 
centibus, ovario pubescente; fructibus globosis, glabris, circiter 
2.5 ecm diametro, 2-locellatis, pericarpio fragile, seminibus 2, 
plano-convexis, ellipticis, 1.3 cm longis. 
A glabrous tree, 8 to 12 m high, the branches and branchlets 
grayish, slender. Leaves chartaceous, oblong-ovate to elliptic, 
8 to 12 cm long, 3.5 to 6 cm wide, pale olivaceous and slightly 
shining when dry, entire, the base acute to rounded, equilateral 
or slightly inequilateral, the apex rather slenderly acuminate; 
lateral nerves about 5 on each side of the midrib, slender, curved, 
anastomosing, distinct on the lower surface as are the lax 
reticulations; petioles 5 to 8 mm long. Pistillate flowers soli- 
tary, axillary, their pedicels about 2 mm long, glabrous. 
Sepals 4, broadly ovate, rounded, 5 to 6 mm long, slightly 
pubescent. Ovary globose, pubescent, 4 mm in diameter, the 
stigma broadly 2-lobed, the lobes reniform, about 2 mm wide. 
Fruits globose, glabrous, about 2.5 cm in diameter, 2-celled, 
2-seeded, brown when dry, brittle. Seeds plano-convex, elliptic, 
about 1.3 cm long. 
MINpoRO, Bongabong River, For. Bur. 4036 Merritt, March 28, 
1906 (type), For. Bur. 12210 Rosenbluth, May 21, 1908. In 
forests at low altitudes, with the local name bato-bato. 
A species probably as closely allied to Cyclostemon microphyl- 
lus Merr. as any other described form, apparently well charac- 
terized by its few-nerved leaves.

HOMALANTHUS CONCOLOR sp. nov. § Monosepali. 
Frutex glaber; foliis orbiculari-ovatis, obscure obtuseque ac- 
uminatis, basi late rotundatis, peltatis, subtus perspicue biglan- 
dulosis, olivaceis, nitidis, utrinque concoloribus, 5 ad 7 cm longis; 
floribus ¢ numerosis, bracteis biglandulosis, unifloris, stamini- 
bus circiter 30; fructibus circiter 5 mm diametro. 
An entirely glabrous monoecious shrub, the branches and 
branchlets brownish olivaceous, smooth. Leaves peltate, or- 
bicular-ovate, chartaceous, 5 to 7 cm long, shining, olivaceous 
and of the same color on both surfaces, apex broadly rounded,
