1. CHAMPEREIA Griffith 
Erect glabrous shrubs or small trees with alternate, entire leaves. 
Flowers minute, in few-flowered cymes which are arranged in axillary 
panicles, the bracts minute. Calyx-lobes 5, valvate. Petals none. Stamens 
5, perigynous, opposite the lobes. Ovary superior, half immersed in the 
disk; stigma sessile, broad; ovule solitary, erect. Fruit an ellipsoid drupe. 
Species 2 or 3, Tenasserim to Malaya, 1 in the Philippines. 
1. C. manillana (Blume) Merr. Malalucban (Tag.). 
An erect glabrous shrub 2 to 4 m high. Leaves shining, oblong to 
oblong-ovate, shortly petioled, 7 to 14 cm long, base acute or rounded, apex 
acute or somewhat acuminate. Panicles pale-green, slender, 4 to 10 em 
long. Flowers pale-green or yellowish-green, about 2 mm long, the calyx- 
lobes oblong-ovate, acute, 1.5 mm long, spreading. Fruit glabrous, fleshy, 
ellipsoid, yellow or red, about 12 mm long, pericarp thin, seed large. 
In thickets, occasional, fl. Jan—March; widely distributed in the Phil-

40. OLACACEAE (OLAX FAMILY) 
Erect or climbing shrubs, or trees, with alternate, simple, entire leaves. 
Flowers small, regular, perfect, in axillary racemes or cymes. Calyx small, 
truncate, or 4- to 6-toothed, accrescent and enclosing the fruit. Petals 3 
to 6, free or coherent, valvate, sometimes cleft. Stamens 3 or more, opposite 
the petals, or alternate with them; staminodes twice as many as the 
stamens, often bifid, or none. Ovary superior, free, 1- to 5-celled, cells 
l-ovuled; style simple. Fruit a drupe or nut-like, surrounded by the 
enlarged, often fleshy calyx. 
Genera 26, species about 150 in the tropics of both hemispheres, 5 
genera and 5 or 6 species in the Philippines. 
OLAX Linnaeus 
Climbing shrubs or trees with alternate, entire, simple leaves. Flowers 
in axillary, simple or branched racemes, the bracts small. Calyx small, 
cup-shaped, truncate or slightly toothed, accrescent and surrounding the 
fruit. Petals 3 to 6, hypogynous, valvate, somewhat coherent or free. 
Fertile stamens 3, the filaments attached near the base of the petals; 
staminodes usually 6, attached near the edges of the petals, bifid. Ovary 
superior, free, more or less 3-celled below, 1-celled above; style simple; 
stigma 3-lobed; ovules 3, pendulous. Fruit nearly covered by the fleshy 
accrescent calyx, the stone 1-celled, 1-seeded. (Latin “smelling” in allusion 
to the rank-scented wood of some species.) 
Species about 30, tropics of the Old World, 1 in the Philippines. 
1. O. imbricata Roxb. Malabaguio (Tag.). 
A scandent shrub reaching a height of 10 m or more, or a small tree 
with pendulous branches, nearly glabrous. Leaves distichous, oblong-ovate, 
obtuse to acuminate, base rounded or acute, 6 to 15 em long. Racemes 
puberulent, many-flowered, dichotomous, 1.5 to 3 em long. Flowers white, 
the calyx truncate. Petals 3, free or nearly so, about 1 cm long, entire,
