A medium-sized tree. Leaves chartaceous, elliptic or oblong
to ovate-lanceolate, apex blunt-acuminate, base rounded or subcuneate, margin crenulate, glabrous except along principal
nerves, where there is a sparse pubescence, mainly of grayish
pilose hairs, with hairy domatia in the axils of nerves on underside, 5.8 to 7.3 cm long, 2.7 to 3.8 cm wide; secondary nerves
10 to 12 pairs; tertiary nerves rather indistinct, mainly reticulate; petioles 3 to 5 mm long. Inflorescences axillary, 4 to 5
mm long, lax, few-flowered; peduncle and branches slender,
glabrous or pubescent. Flowers "small, violet, not odorous, and
not showy," about 3 mm long, on stout, pubescent pedicels 1 to
1.5 mm long. Sepals broadly ovate, acute at apex, about 1.5
to 2 mm long and wide, tomentose outside, smooth within. Petals oblong, about 3 mm long and 1 mm wide, tomentose outside,
glabrous within. Stamens 15, small; filaments filiform, slightly
expanded at base, several times longer than anther; anther
oblong, about 0.1 mm long; appendage to connective aristate,
considerably longer than anther. Ovary and stylopodium tomentose, about 1.3 mm long and 0.6 mm in diameter, abruptly
tapering into 0.3 mm long style; stigma minute. Fruit ovoid,
about 1 cm long and 9 mm in diameter. Calyx lobes triangularovate, imbricate, rather closely surrounding and a little shorter
than fruit. Margins of calyx lobes frequently brownish and
scarious, sometimes very slightly reflexed. Fruit conical, faintly pubescent, with thin pericarp, the short style projecting
through a small circular depression at apex. Style glabrous,
about 0.5 mm long.
MINDANAO, Zamboanga Province, Naganaga, For. Bur. 21895
Villamil (type in the Philippine National Herbarium), May 18,
1914. The flowers were described from For. Bur. 31304 Zamuco, collected in Zamboanga Province, April, 1930.
This species has been found only in one district. The wood
seems to be of the quality of dalindingan.
Symington 81 has called attention to the close relationship of
this species to B. Curtisii King, and, possibly, to another species
of the Malay Peninsula.
5. Genus PENTACME A. de Candolle
The generic characteristics, as given by Brandis, are:
Sepals strongly imbricate. Petals broad, spreading. Stamens 15. Anthers oblong, on short broad filaments. Anther-cells equal, each prolonged
