Description
Shrub, high up to
2 m
.
Compound leaves are
12–46 cm
long; rachis rather thin, ca
28 cm
long; leaflets 3–9, alternate; chartaceous, leaflets blades 7–18 ×
4–10 cm
, glabrous, inequilateral, pointed at the base, abruptly acuminate at the tip, very slightly denticulate, with few oil glands; lateral veins, 6–9 pairs, prominent on lower surface; petiolules cylindric, glabrous,
3–4 mm
long; petiole cylindric, glabrous. Cymes are terminal, with a few small white flowers, much shorter than the leaves; pedicels longer than flowers, with 2 small bracts at the base or lower third. Flower buds are long, 6 ×
2.5 cm
, yellow-green, fragrant; calyxes 4-connate, indistinct, very shortly ciliate sepal with a big oil gland; petals 5, lanceolate,
4–6 mm
long,
1.5 mm
wide, glabrous, a few oil glands. Stamens are 10,
4 mm
long; filaments dilated and pubescent upper; anthers attached by the back, oval, with a few hairs. Disks are extremely short. Ovaries are cylindric, warty, glabrous, and distinctly constricted at ca ⅓ from the apex; styles longer than ovaries, with elongated styles, and pubescent lower; stigmas inconspicuous. Berries are oval, diameter
5–10 mm
, glabrous, with glands, and red when ripe, containing 1-2 seeds.
Phenology
Flowering between June and July, while fruiting from August to December.
Distribution and habitat
China
, SW
Guangxi
(Longzhou, Daxin, Jingxi, and Napo);
Vietnam
. Growing in forestry of limestone hill or valley forests between alt. 550 and
1400 m
.
Remarks
The species
Bergera macrophylla
shares few similarities of flowers with
B. kwangsiensis
, but both are so different in many morphological characteristics (
Mou
et al.
2020
). However, the taxon is more similar to
B. glabra
from
Vietnam
in leaf morphological characteristics, and different having fewer oil glands in the mesophyll, smaller cymes, fewer flowers and fruits.
