a deciduous shrub with smooth yellow-brown barks that grow to as
tall as 2m in height, inhabits foothill swamps or damp plains, with
branch ends drooped. Leaves are opposite, blades measuring 3-7cm
long, 1.5-3cm wide, obovate-oblong, tip portions becoming narrower
in a tail way, bases cuneate, with margins coarse serrations on
upper halves. Both surfaces and bottoms have no hairs on them.
However, there are many glandular dots on the backside. Cymes appear
from points above axils and give 10-20 light red-purple flowers,
each aperture in 4, and lobes open flat. Corollas are as long as 3mm
long. Stamens are 4 in number, and pistils one, both of which
project outside the corollas. Drupes, spherical, mature in purple.
Bloom time: July-August.
