Characteristics

Shrubs or trees, to 3(–5) m. Stems: new growth essentially glabrous, lines of curved hairs absent. Leaves: stipules narrowly triangular, 1–2.5 mm; petiole to 1/3 blade, adaxial groove hairy with minute, ± sinuous hairs; blade lanceolate-ovate to ovate, unlobed, 3.5–10.5 × 1.5–4 cm, base rounded to cuneate, margins coarsely serrate in distal 2/3–3/4, apex acute to short-acuminate, ± pinnately veined, surfaces glabrate, nectary present abaxially on midvein near base. Inflorescences solitary flowers in axils of distal leaves. Pedicels jointed at middle or distally, 7.5–15 cm; involucellar bractlets 6–8, triangular, 0.06–0.18 cm, margins not ciliate. Flowers pendulous; calyx divided 1/8–1/2 length, often 3-lobed, tubular to narrowly funnelform, (1–)1.4–2 cm, lobes broadly triangular, apices acute to obtuse, glabrate, neither accrescent nor inflated, nectaries absent; petals strongly recurved, rose-pink to red, darker on veins, broadly to narrowly obovate, deeply and irregularly pinnatifid-laciniate, 4–6.5 × 1.5–3.5 cm, glabrous; staminal column straight or curved apically, pendulous, pink to red, 5.5–9 cm, bearing filaments in distal 1/3–1/2, free portion of filaments not secund, 4.5–7.5 mm; pollen yellow; styles pink to red, 7–15 mm; stigmas pink to red. Capsules brown, oblong-cylindric, 3.5–4 cm, glabrous or puberulent. Seeds brown, angulately reniform-ovoid, 2–3 mm, smooth, glabrous or puberulent. 2n = 34, 40, 42, 45 (all cultivars).

Shrub up to 4 m high, glabrous or nearly so. Leaves rather short-petiollate, the petiole slender, up to 1.7 cm long, canaliculate and stellate-hirtellous above, the stipules subulate-filiform; blade elliptic to narrowly elliptic, acute to obtuse at the base, acute at the apex, serrulate-denticulate at the margin, up to 6 cm long and 2.5 cm wide, glabrous, usually 3-palminerved, the nervation slightly prominent beneath. Flowers showy, solitary in the upper leaf axils, pendent, the pedicels very long, slender, articulated near the middle, up to 14 cm long, glabrous to minutely papillate; epicalyx none or the bractlets usually very minute; calyx tubular-cam-panulate, irregularly lobed, 15-20 mm long, spathaceous, glabrous or minutely papillate; petals reflexed, obovate, long-unguiculate, deeply pinnately dissected into numerous oblong or= spatulate lobes, 4-7 cm long, pink or red; staminal tube slender, 5-lobulate at the apex, well exceeding the corolla and up to 9 cm long, antheriferous on the upper part, the filaments up to 7 mm long; style much longer than the staminal tube, the style branches ca 10-12 mm long, the stigmas fimbril-late. Capsule oblong-cylindraceous, obtuse, the seeds glabrous.
Shrubs evergreen, erect, to 3 m tall. Branchlets slender, usually pendulous, glabrous. Stipules subulate, ca. 2 mm, usually caducous; petiole 1-2 cm, stellate; leaf blade elliptic or oblong, not lobed, 4-7 × 1.5-4 cm, papery, glabrous, base obtuse or broadly cuneate, margin dentate, apex acute or shortly acuminate.
