Characteristics

Succulent perennial herb to 2.3(–3) m. high, possibly rhizomatous (see Glover & Samuel 3305; further observations required); stems solitary or several, simple or branched, glabrous, woody at the base.. Leaves on new growth, opposite and decussate, up to 5 mm. between nodes, rarely to 17 mm., sessile, broadly to narrowly obovate or linear-lanceolate (in southern Africa), 4.5–10 cm. long, 2–6 cm. broad, apex obtuse, sometimes obtuse and shortly acuminate, base long or shortly cuneate, succulent, glaucous, median carina sometimes distinct, somewhat coriaceous.. Inflorescence a terminal, much-branched, subglobose, paniculate cyme; peduncle stout, up to 34 cm. long, with 1–2 pairs of subopposite early caducous leaf-like bracts at approximately one-third intervals; pedicels up to 4 cm. long, glandular-pubescent; bracteoles ± 0.5 mm. long, papery; flowers erect at first, later pendent.. Calyx-tube hemispherical, ± 2 mm. long, becoming markedly indented at the base with age accompanied by a swelling of the pedicel at the junction with the calyx, glandular-pubescent; lobes ovate, up to 7 mm. long, 4 mm. broad, acute, persistent, glandular-pubescent.. Corolla-tube tubular-urceolate, ± 15 mm. long, fluted, gibbous at the base; lobes linear-lanceolate, ± 15 mm. long, 3 mm. broad, acute, recurving with age, glandular-pubescent, greenish yellow or salmon-pink to crimson.. Stamens 10; filaments slender, hairy near the base, free for 22 mm.; anthers oblong-ovate, 2 mm. long, 1–5 mm. broad.. Nectary scales stoutly clavate, 4 mm. long, 3 mm. broad, obliquely truncate-depressed, projecting into the cavity formed by the gibbous corolla.. Carpels ± 10 mm. long extending into the slender style; styles 15 mm. long, apex outwardly curved.. Seeds numerous, oblong-lancolate, 1 mm. long, longitudinally striate.. Fig. 9.

Shrubs up to 2 m high, with stems erect, usually much branched. Leaves opposite, oblanceolate to linear, (40-)60-120(-160) x (10-)20-45 mm, cuneate, acute or mucronate, dorsiventrally flattened and slightly convex on both surfaces to almost terete or somewhat grooved above, glabrous to more or less glandular-pubescent, green to greyish brown. Inflorescence a thyrse with 3-5 dichasia each with 3-many flowers; peduncle 0.2-0.35(-0.6) m long, glabrous to more or less glandular-pubescent. Calyx: lobes triangular-ovate, 8-10 mm long, acute, often densely covered with glandular hairs. Corolla orange to deep red; tube ampullaceous, 14-16(-18) mm long, bulging between calyx-lobes, glabrous to densely covered with glandular hairs on outside, glabrous on inside except for tuft of hairs where filaments are fused to tube; lobes linear-lanceolate, recoiled. Anthers 2.7-3 mm long. Squamae oblong, (2.5-)3-4.5 x 1.2-1.8 mm, with cup-shaped depression on apex, yellow.
Leaves decussate, condensed to subrosulate at the end of sterile shoots and below the peduncles, obovate to oblong–obovate or subcircular, 2·5–10 x 3–6·5 cm., obtuse or rounded at the apex, entire and flat at the margin or the upper ones undulate,.sessile or contracted to attenuate into a terete petiole–base, or lanceolate to spathulate, shortly acuminate and acute, apiculate, or sometimes oblong to narrowly linear up to 16 cm. long and 3 mm. broad, flat, concave or channelled above, ± convex beneath, sometimes semi–terete, fleshy, rigid on drying, glabrous and glaucous tinged pink or red or whitish, or shortly glandular–pubescent.
Corolla 2·5–3·7 cm. long, deep red, orange–red or coral–red (in F.Z. area), glandular–pubescent on the outside; tube c. 1·2–1·5 cm. long, rather swollen at the base and there 5–angled and subwinged at the angles, contracted above the sepals and thence subcylindrical; corolla–lobes c. 1·8–2 cm. long and ± 2 mm. broad, oblong–linear or linear–lanceolate, oblique at the apex, obtuse, apiculate, reflexed.
Stamens exserted; filaments c. 2·2 cm. long, dilatate and hairy at the base, the hairs long, dense; anthers c. 1·5 mm. and suborbicular or 2·25–2·5 x 1·25 mm. and oblong (the two anther–types present in flowers of a single inflorescence, sometimes even in one flower), yellow.
Inflorescence cymose, up to 20 cm. in diameter, many–flowered; peduncle 19–40 cm. long, terete, sparsely glandular–pubescent just below the inflorescence, glabrous lower down; pedicels 1–3·7 cm. long, shortly and densely glandular–pubescent.
Shrub, up to 2 m high. Leaves oblanceolate to linear, glabrous to ± glandular-pubescent. Flowers pendulous. Corolla tube bulging to almost saccate between calyx lobes. Squamae obpyramidal. Flowers orange to deep red.
Calyx densely glandular–pubescent on the outside; tube 1–2 mm. long to absent; sepals 6–10 x 4–5 mm., ovate, ovate–oblong or triangular, acute or subacute.
Stem strong, ascending, branching from the base, leafless like the branches nearly up to the peduncles, glabrous.
Follicles 1–6 cm. long, attenuate into the styles, glabrous; styles c. 9 mm. long, exserted; stigmas capitellate.
Scales 2·5–3 mm. long, oblong, tubular above, dilatate and irregularly lobed or cut at the margin.
A succulent shrub up to 2(4) m. tall, forming clusters several feet across.
Seeds c. 0–6 mm. long, oblong.
Flowers pendulous.
