Shrubs, to 4 m, flowering at 1 m; rhizomes absent. Stems clustered, branches occasionally arching to the ground and rooting at nodes; bark yellow to red, not corky, loosely verrucose; branchlets bright red, reddish brown, maroon, or green, occasionally green in winter and maroon in summer, appressed-hairy when young; lenticels protruding on 2d year branches, area surrounding them not suffused with purple on older branches; pith white. Leaves: petiole 5–38 mm; blade lanceolate, elliptic, or ovate, 3.5–20 × 1.5–12 cm, base cuneate, apex acute to acuminate, abaxial surface white, hairs appressed except near secondary vein axils, tufts of erect hairs present in axils of secondary veins, adaxial surface green, hairs appressed, sparse; secondary veins 5–7 per side, most arising from proximal 1/2, tertiary veins not prominent. Inflorescences flat-topped, 3–6 cm diam., peduncle 20–40 mm; branches and pedicels green to yellow-green, turning maroon in fruit. Flowers: hypanthium densely appressed-hairy; sepals 0.2–0.6 mm; petals white to cream, 2.5–4 mm. Drupes white, globose or subglobose, 6–10 mm diam.; stone subglobose, laterally compressed, 4–6 × 4–6 × 1.5–3 mm, furrowed laterally, apex rounded. 2n = 22.
"Shrub 1–3 m, often forming dense thickets; twigs bright red; pith large and white; lvs lanceolate to elliptic or ovate, mostly 5–10 cm and a third to two-thirds as wide, acute to gradually acuminate at the tip, acute to broadly rounded at base, distinctly whitened beneath; lateral veins in well grown lvs 5–7 to a side; infl flat or slight convex; fr white (reputedly sometimes blue), 7–9 mm; stone brownish-black, with 7–9 vertical yellow stripes; 2n=22. Streambanks and moist woods; Nf. to Alas., s. to Pa., Ind., Ill., and n. Mex. May–Aug. Pubescence of the lower lf-surface typically sparse and strictly appressed, that of the twigs minute and mostly appressed. (C. baileyi, a form common about the Great Lakes and in s. Ont., with the pubescence partly spreading; C. interior, a chiefly western form, also found e. to Mich. and Ind., with the infl and twigs tomentose) (C. stolonifera)"
