Characteristics

Plant succulent, with stems 3-4 cm diam., simple or branched, up to 1 met. long, procumbent, with the apical 20-30 cm foliate and ascending; stems sub-erect when supported by bushes, procumbent in open positions with numerous offshoots forming dense groups of more or less erect rosettes. Leaves about 20 in a sub-dense rosette, lanceolate-attenuate, sheathing at base, up to 18 cm long, 5-5 cm broad near base; upper surface rather flat, slightly canaliculate towards apex; lower surface convex; both surfaces rather bluish-green with numerous irregularly scattered oblong white spots throughout, the spots sometimes slightly raised but hardly tuberculate; margins usually with a whitish horny edge, minutely serrate, with teeth about 0.5 mm long, 5-8 mm distant. (Note: In lower third, teeth are obsolete, the margins having a straight white horny edge; the middle third is somewhat serrate, while in upper third the teeth and horny edge are obsolete; apices of leaves usually terminate in a white spine.) Inflorescence up to 50 cm high, simple, or with 1, occasionally 2, branches from about the middle. Peduncle flattened low down and about 2 cm diam., with several ovate-acute 7-9-nerved sterile bracts below the racemes. Racemes densely capitate, usually rather corymbose, about 6 cm long and 9 cm diam. Bracts lowest 10 mm long, 3-4 mm broad at base, thin scarious about 5-nerved. Pedicels mostly 35 mm long. Perianth frequently 40 mm long, nearest Peach Red (R.C.S. I) turning paler at mouth, rather cylindrical or sometimes very slightly clavate, slightly curved; outer segments free for 20 mm from apex, the lower 20 mm sometimes tightly cohering to the inner segments or sometimes connate into a tube, very obscurely nerved, the nerves greenish at apex, apices sub-acute, slightly spreading; inner segments free, but cohering to the outer for half their length, white with thin edges; with a keel the colour of the perianth for its greater length turning greenish at apex, apices more obtuse more spreading than the outer. Filaments filiform-flattened, pale lemon throughout. Anthers exserted up to 3 mm Stigma at length exserted up to 3 mm. Ovary 7 mm long, 3 mm diam. at base, slightly tapering into the style. Stigma at length exserted 3 mm.
More
Plants decumbent, 150-400 mm tall, leaves present in apical 200-300 mm of stems. Leaves ±20 per stem, broadly deltoid, 120-200 x 35-60 mm, bluish green with scattered white spots, keels rarely dentate. Inflorescence a simple to twice-branched, very dense, capitate raceme, up to 500 mm tall; peduncle with few sterile bracts; bracts ovate, 9-11 x 3-5 mm, 5-nerved. Flowers orange-red, 30-40 mm long; outer segments free for + half their length, inner segments free but adhering to outer for ± half their length; pedicels 35-50 mm long. Anthers exserted up to 3 mm. Ovary 7-8 x 2-3 mm; style exserted up to 6 mm. Fruit not seen.
Succulent shrublet with creeping stems to 1 m, simple or branched, with persistent dried leaves. Leaves blue-green, with copious white, irregularly scattered, oblong spots on both surfaces, lanceolate-attenuate, to 20 cm long; margins whitish, with tiny teeth. Racemes capitate, subcorymbose, dense, simple or occasionally branched, to 50 cm long. Flowers red, paler toward mouth, 40 mm long; stamens and stigma exserted.
Dense, medium-sized shrub, 150-400 mm tall. Stems numerous, creeping, leafy portions always erect. Leaves blue-green, fairly narrow, up to 200 mm long, copiously white-spotted on both surfaces, upturned, quite densely arranged in terminal rosettes, margins with whitish edges and very small teeth. Flowers in tightly packed, rarely branched, capitate panicles, pale red. (In north) July-Dec. (in south).
