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 5 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 cm diametro, 2-locellatis, pericarpio fragile, seminibus 2, 

 piano-con vexis, 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. 



MiNDORO, 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. § ^onosepali. 



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 s numerosis, bracteis biglandulosis, unifloris, stamini- 

 bus circiter 80; 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,
