Euonymus atropurpureus.   Wahoo,

ORIGIN:  Eastern and central USA and Canada.
DESCRIPTION: It is a deciduous shrub growing to 8 m tall, with stems up to 10 cm diameter. The bark is gray, smooth, and lightly fissured. The twigs are dark purplish-brown, slender, sometimes four-angled or slightly winged. The leaves are opposite, elliptical, 8.5–11.3 cm long and 3.2–5.5 cm broad, abruptly long pointed at the tip, and with a finely serrated margin; they are green above, paler and often with fine hairs beneath, and turn bright red in the fall. The flowers are bisexual, 10–12 mm diameter, with four greenish sepals, four brown-purple petals and four stamens; they are produced in small axillary cymes. The fruit is a smooth reddish to pink four-lobed (sometimes one or more of the lobes abort) capsule, up to 17 mm diameter, each lobe containing a single seed, orange with a fleshy red aril. The bark occurs in curved pieces or quills, 2-4 mm thick. Outer surface light brown, wrinkled.  Root bark may have root scars and adhering rootlets. Stem bark is smoother with lichens usually present. The inner surface is striated porous, sometimes with adherent patches of yellow wood. Fracture short but friable, showing a narrow brown cork, a whitish cortex and a darker phloem.
