Habit | Plants 1–3 m. Stems erect to spreading, ± pubescent throughout; spines at nodes absent or 1–3, 5–20 mm; prickles on internodes absent or sparse. | Plants 1–2 m. Stems erect to spreading or prostrate, finely puberulent, sometimes glabrous except for prickles, not glandular; spines at nodes 1–3, 3–12 mm; prickles on internodes scattered to dense. | ||||||||
Leaves | petiole 1–3 cm, pilose with glandular and eglandular hairs, some plumose hairs at base; blade roundish to nearly reniform, 3- (or 5-)lobed, cleft 1/2 to midrib, proximal segments again shallowly cleft into 2 unequal lobes, 2–3.5 cm, base rounded to cordate, surfaces pubescent abaxially, subglabrous or finely pubescent adaxially, lobes cuneate, margins prominently crenate-serrate, apex rounded. |
petiole 0.7–5.5 cm, pubescent, stipitate-glandular; blade pentagonal, 3–7-lobed, cleft 1/2+ to midrib and again irregularly shallowly cleft, 1–7.8 cm, base truncate or cordate, surfaces glabrous or sparsely puberulent, sometimes glandular on main veins abaxially, sometimes with scattered, yellow, sessile, crystalline glands, lobes acutish, margins deeply 1 or 2 times crenate-dentate, apex acute. |
||||||||
Inflorescences | pendent, solitary flowers or 2–4-flowered racemes, 2–4 cm, axis glabrous or pilose, flowers evenly spaced. |
spreading to pendent, 5–18(–25)-flowered racemes, 3–4 cm, axis reddish stipitate-glandular and puberulent, flowers evenly spaced. |
||||||||
Pedicels | not jointed, 3–12 mm, glabrous or pilose; bracts oval, 1–2 mm, glabrous or ciliate with stiff hairs and glands. |
jointed (joint sometimes obscured by glands and difficult to see especially on short pedicels; may appear as darker line immediately proximal to ovary), 2–10 mm, glandular-bristly; bracts linear-lanceolate, 1.8–4 mm, puberulent and reddish or purplish stipitate-glandular. |
||||||||
Flowers | hypanthium greenish or purplish, obconic, 1.5–3.5 mm, glabrous or copiously pubescent; sepals not overlapping, spreading-reflexed, red or reddish or purplish green, narrowly oblong-deltate, 3.4–6 mm; petals distally nearly connivent to overlapping, erect, white or pink to red, cuneate-lunate to obovate, not conspicuously revolute or inrolled, 1.2–3 mm; nectary disc not prominent; stamens 2.5–3.5 times as long as petals; filaments linear, 3.5–7 mm, glabrous; anthers cream, oval, 1 mm, apex rounded; ovary glabrous; styles connate ca. 1/2 their lengths, 5–11 mm, copiously pilose-villous in proximal 3/4. |
hypanthium cream to orangish, shallowly saucer-shaped to crateriform, (0.7–)1–1.2(–1.5) mm, glabrous; sepals somewhat overlapping, spreading or reflexed, cream to pale yellowish green or dull reddish brown, reddish color deepening with age, very broadly ovate-oblong, 1.5–3.5 mm; petals widely separated, erect, pale yellowish green distally and reddish proximally to reddish throughout, broadly fan-shaped to semicircular, cuneate-flabellate, not conspicuously revolute or inrolled, 1–1.5(–1.7) mm; nectary disc prominent, pinkish, raised, angled, covering most of ovary; stamens slightly longer than petals; filaments linear, 1.1–1.7 mm, glabrous; anthers yellow, transversely oblong, 0.5–1 mm, broader than long, apex blunt; ovary sparsely to thickly stipitate-glandular with slender, usually reddish- to purplish-tipped hairs, rarely glabrous; styles connate to middle, 1.4–2 mm, glabrous. |
||||||||
Berries | palatable, purplish black, subglobose, 6–12 mm, glabrous. |
palatable but insipid, red, becoming black or dark purple, ellipsoid, 4–8(–14) mm, slenderly stipitate-glandular, bristly with reddish stipitate-glandular hairs. |
