Flowers: calyx pale yellow flecked with red, inflated, 25-50 mm, (papery), tube 24-40 mm, lobes deltate, to 10 mm, shorter than tube, apex acute; corolla with tube greenish white and exserted portion maroon, 30-70 mm, contracted basally, (sparsely glandular-puberulent), lobes oblong-ovate to triangular, 10-20 mm, apex acuminate. 2n = 40.
Perennial, little-branched herb as much as 1 m. tall or taller, the stems fleshy, glabrous, lustrous, the roots diffuse. Leaves opposite, simple or less frequently 3- to 5-pinnate (usually both simple and pinnate leaves on the same plant), in compound leaves the terminal leaflet the largest; blade of leaf or leaflets oblong, rounded at base and apex; coarsely crenate, glabrous, as much as 13 cm. long and 7 cm. broad, fleshy and obscurely nerved, capable of producing plantlets from the indentations of the leaf margin; petiole conspicuous, commonly 3-4 cm. long on older leaves, fleshy, glabrous, widened toward the base, exstipulate but with de- current interpetiolar lines on the subtending internode. Inflorescence a glabrous, terminal, thrice-compound panicle as much as 5 dm. long, the bracts and bractlets minute and caducous. Flowers large and conspicuous, with pedicels mostly about 1 Cm. long; calyx broadly tubular, inflated, usually about 3 cm. long and 1 cm. broad, 4-lobed for one-fourth or one-fifth its length, greenish often tinged reddish; corolla tubular, 4-5 cm. long, mostly enclosed by the calyx, markedly constricted just above the ovary and thence ventricose, 4-lobed, the lobes triangular and acuminate, glabrous, reddish; stamens 8, inserted at the base of the corolla tube, the filaments almost as long as the corolla.
Calyx cylindrical; tube up to 25 mm. long, 8 mm. diameter, slightly indented at the base, green with longitudinal reddish mottlings near the base, green above; lobes ovate-triangular, 7–10 mm. long, abruptly acuminate, persistent in fruit.
Inflorescence a lax terminal cyme; leaves of inflorescence similar to the foliage leaves but smaller, lower 3–5-foliate, simple above and on the ultimate branches; pedicels slender.
Stamen-filaments adnate to the corolla-tube below the constriction, free for 25–27 mm.; anthers oblong, 3 mm. long.
Corolla cylindrical, green below, red above; tube 30 mm. long, strongly constricted ± 8 mm. from the base, markedly 8-fluted and gibbous below the constriction, sparsely glandular-pubescent, especially near the base; lobes oblong-ovate, ± 10 mm. long and 6 mm. broad, abruptly long-acuminate, recurved.
Leaves opposite and decussate, in adult plants only present in the upper parts, ± leafless at anthesis; lower leaves simple, upper often 3- or 5-foliate; leaf-blade oblong-oval up to 9 cm. long and 5 cm. broad, possibly larger, apex obtuse, base cuneate to truncate, margin crenate, sometimes obscurely so, glabrous; leaflets of compound leaves similar to simple leaf; petiole ± 3 cm. long for simple leaves, up to 6 cm. and more for compound leaves, semi-amplexicaul.
Succulent perennial herb, probably rhizomatous up to 2 m. high; stems branched from the base, somewhat woody at the base, glabrous.
Seeds ellipsoid-oblong, ± 0.5 mm. long, obscurely longitudinally striate.
Carpels oblong-ovoid, up to 10 mm. long, free or slightly connate at the base; style slender, 27–30 mm. long.
Nectary scales subrectangular, ± 2 mm. long, 1.7 mm. broad, adhering to the base of the carpels, yellow.
Corolla longer than the calyx; tube 25–40 mm. long, suburceolate–8–angled at the base, constricted above the carpels and then elongate–tubular–4–angled, green below, bright red or purple upwards; corolla–lobes 9–14 x 4·3–6·5 mm., deltate, abruptly acuminate, very acute, spreading.
Leaves decussate, imparipinnate, sometimes some or all of them reduced to the terminal leaflet; lamina 6–20 x 4–12 cm.; leaflets 3–5, circular, ovate or ovate–oblong to oblong–spathulate, the terminal one the largest, obtuse, broadly crenate, doubly crenate or crenate–dentate at the margin, usually contracted at the base or sometimes attenuate into a petiolule, flat, green with violet lines on the upper side; petiole 2–10 cm. long, semi–amplexicaul.
Stem up to 2 m. long, erect or ascending, stout, terete, simple, spotted or striped with red, sometimes with sterile shoots at the base.
Calyx broadly cylindric–tubular, sunk at the base, green, sometimes striped with red or red–violet; calyx–tube 21–31 mm. long; lobes 7–10·5 x 7–11·25 mm., deltate to subsemiorbicular, acute.
Flowers pendulous, in cymes grouped in terminal, ample loose panicles; pedicels 10–25 mm. long, slender, divaricate, reflexed at the extremity.
Follicles 12–14 mm. long, ovoid, connate at the base for 2·2–3·5 mm., attenuate into the styles; styles 22·5–30 mm. long.
A completely glabrous perennial, succulent plant.
Stamens slightly exserted; filaments inserted below the middle of the corolla–tube; anthers 2·6–3 x 1·6–2·2 mm., ovate.
Seeds c. 0·8 x 0·35 mm., obovoid, obtuse.
