Characteristics

Plants are tufted, solitary or branching from the base forming clumps, sessile to shortly stemmed, reaching 25 cm high on flowering. Leaves numerous, linear-lanceolate to almost subulate, up to 50 mm long, arising from a tuberous rootstock, the leaves slightly convex to flattened above, convex below, densely to sparsely covered by linear clusters of retrorse hairs, to almost glabrous, apex acute, margins entire, the leaves widespread to incurved. Inflorescence is a pedunculate thyrse, the peduncle hairy with short retrorse hairs, with three hairy linear-lanceolate, acute bracts at each of 2-3 nodes, fused at base for 0.5-1 mm, below the inflorescence and three sessile or stalked subinflorescences, forming whorls at each of 3-5 nodes apically. Flowers clustered, sessile, tubular and white, up to 5.5 mm long; calyx green often with a purplish tinge, hairy, with downward pointing hairs, approximately 50-76% of the length of the flower, lobes bluntly lanceolate, rounded at the apex, margins with long horizontal to upward curved cilia, decreasing in length apically. Petals panduriform with irregularly serrulate margins, green, granular to papillose dorsally, and with large round terminal appendages, and incurved apices. Carpels slender, pyriform, with slightly recurved styles and dorso-lateral stigmas. Squamae oblong-cuneate, length approximately 1.5 to twice as long as broad, brownish-orange.
More
Perennials, usually with several basal rosettes, more or less branched, with carnose to slightly woody branches, with old leaves remaining attached to stem. Leaves oblong-elliptic, rarely linear-lanceolate or obovate to orbicular, 20-80(-150) x (4-)6-15(-25) mm, acute to rounded, flat or slightly convex above, more or less convex below, spreading, rarely somewhat recurved in the north-east, glabrous to pubescent, with or without marginal cilia, green to yellowish green to brown. Inflorescence an elongate, sometimes a spike-like thyrse with many dense dichasia stalked or sessile (i.e. part-inflorescences are produced from (2-)3-5(-7) nodes of central axis), with peduncle 0.l-0.2(-0.4) m long and glabrous to pubescent. Calyx: lobes oblong-triangular, l.5-2(-3) mm long, obtuse, rarely acute, glabrous or with recurved hairs or papillae and marginal cilia, fleshy, green to brown. Corolla tubular to almost cylindrical, fused basally for 0.5-0.8 mm, cream, rarely white; lobes panduriform, 3-3.5(-4.5) mm long, each with an ellipsoid dorsal appendage in terminal position and with membranous petal apex on inside. Stamens with yellow anthers. Squamae oblong-cuneate to almost square, 0.6-1 x 0.4-0.5 mm, usually slightly emarginate, first abruptly, later gradually constricted towards base, fleshy, yellow.
Perennial succulent, several basal rosettes, branched, erect, carnose to woody, 0.150.45 m when in flower, old leaves not deciduous. Leaves oblong-elliptic, 20-80 x 6-15 mm, acute to rounded, flat above, convex below, glabrous to pubescent, with or without marginal cilia, green to brown. Inflorescence an elongate, terminal thyrse with several dense stalked or sessile dichasia from 3-5 nodes; flowers sessile; peduncle 0.1-0.2 m long, glabrous to pubescent. Calyx fleshy, green to brown, hairy, marginal cilia. Corolla tubular, fused 0.5-0.8 mm, cream-coloured; lobes panduriform, 3.0-3.5 mm long, terminal ellipsoid dorsal appendage present, apex membranous on inside. Flowering time Sept.-Dec.
Woody or fleshy, branched perennial, with several basal rosettes, 50-250 mm tall. Leaves oblong-elliptic to orbicular, flat and slightly convex above and convex below, 20-80 x 6-15 mm, glabrous to pubescent. Flowers, in many dense stalked or sessile clusters, in an elongated to spike-like inflorescence, on a pubescent peduncle 0.1-0.2 m long, tubular, petals 3-3.5 mm long, fused in lower 0.8 mm, with a fleshy, terminal appendage, cream to white.
Tufted perennial with fleshy branches. Leaves oblong-elliptic, to orbicular, glabrous or pubescent, margins often ciliate. Flowers in small clusters forming elongate panicles, white to cream-coloured, ± 4 mm long.
