a deciduous shrub with gray-brown barks, inhabits limestone or serpentinite areas, branching well to grow thick to approximately 2m
in height. Leaves are of opposite phyllotaxis, 1-3cm long, oval to
lanceolate-like oblong, with tips pointed, bases cuneate, margins
entire, and coarse hairs on veins on both sides and margins.
Petioles are 4-7mm long, and the pairs' grounds swell to merge. New
branch tips generally give two light-red-tinging flowers with
3-6mm-in-length peduncles. Corollas are funnel-shaped, and floral
tubes measure 1-1.5cm, with tips cleft in 4 and open flat. Bloom
