a deciduous small- tree to tree, grows in sunny thickets. Leaves
are opposite phyllotaxis; blades measure 5-12cm long, 3-6cm wide,
oblong to long-oblong, with tips abruptly becoming strong, broad-cuneate-shaped
bases, and fine serrations on margins. Deep to dark red, flowers set
themselves 2 or 3 on branch tips or axils; corollas are
funnel-shaped, 2.5-4cm long, and the upper parts are cleft in five.
Floral tubes' upper halves somewhat abruptly expand in a bell shape.
Ovaries, 1-1.3cm long, cylindrical, are seemingly peduncles, as
those positioned beneath calixes, besides slender and cylindrical.
Bloom time: May-June.
