Characteristics

Erect, many-stemmed, relatively sparsely branched, conical or broom-like shrubs, 0.3-1.0 m high, 300-400 mm in diameter, not or rarely spinescent. Old stems displaying anomalous secondary growth, 15-30 mm in diameter, grey-brown; dolichoblasts bright green to yellowish, sparsely to densely white-felty and glandular; older branchlets grey to grey-brown, delicately branched, tending to be vertically orientated; brachyblasts short-lived, sometimes very long with leaves at apex. Leaves opposite, rarely alternate on flowering shoots, linear, (0.75-)1.0-3.5(-7.0) x 0.2-0.5 mm, entire, adaxially flattened, concave towards base, abaxially convex, initially densely felty, glabrescent, or permanently hairy, when glabrous shiny, bright green or dull green, pitted with glands in cavities, apex obtuse to slightly acute, base broadened and semi-amplexicaul; leaves on brachyblasts conspicuously decussate, imbricate, initially shortly felty, glabrescent or permanently hairy; those on dolichoblasts scattered, sessile on permanently callous, cushion-like thickenings, much longer than those on brachyblasts. Capitula heterogamous disciform, spicate racemose or racemose or solitary on brachyblasts, rarely paniculate, 1.5-2.5 mm long; peduncle 1.0-5.5 mm long, sometimes almost absent, felty, glabrescent. Involucral bracts 4, ovate to lanceolate, up to 2 x 1.5 mm, 2 slightly keeled, other 2 laterally flattened, central part herbaceous, green, margin broad, membranous, purple, abaxially sparsely felty to sericeous, glabrescent, with permanent, almost sessile glands in cavities. Paleae: those of marginal florets free, 1.5-2.0 mm long, ovate, keeled and enveloping florets, abaxially long-lanate, hairs septate; those of disc florets linear, 2.0 x 0.3 mm, membranous, margins fringed, abaxially lanate. Marginal female florets (1)2, 2.0-2.5 mm long; corolla narrowly tubular-filiform; lamina extending at most to furcation of style, yellow, cylindrical. Style branches flattened, linear, apex acute. Ovary oblong to oblanceolate, slightly flattened, long-lanate. Seeds 1.2-2.2 mm long, obovoid, slightly flattened. Disc florets (1-)3-5(-7), functionally male with sterile ovary, 2.0-2.5 mm long; corolla tubular to trumpet-shaped, 5-lobed, red-purple, sometimes yellow towards base. Stamens 5, exserted at maturity. Style unbranched, cylindrical, apex globose, with sweeping hairs. Receptacle after anthesis with dense, white, long hairs between involucral bracts and marginal paleae.
More
Erect, many-stemmed, relatively sparsely branched, conical or broom-like shrub, 0.3-1.0 m high. Leaves opposite or decussate, rarely alternate on flowering shoots, small, linear, entire, initially densely felty, glabrescent, shiny, bright green (in subsp. ericoides). Capitula disciform, spicate racemose or racemose or solitary, rarely paniculate, sessile to shortly pedunculate; involucral bracts 4, ovate to lanceolate, central part herbaceous, green with broad, purple, membranous margins. Receptacle paleate, all paleae free, hairy on the outside. Outer female florets (1)2, corolla tubular-filiform, yellowish. Disc florets (1)3-5(7), tubular to trumpet-shaped, red-purple, sometimes yellow towards base. Flowering time Feb.-May. Pappus absent. Cypselae oblong to oblanceolate, slightly flattened, long-lanate.
Twiggy, conical or broom-like shrub, up to 1 m tall. Leaves usually opposite on flowering and short-shoots, minute, linear, 1-5(-7) mm long, glabrescent with pitted glands. Flowerheads spicate-racemose or solitary on peduncles 1-5.5 mm long, disciform, 1.5-2.5 mm long, purplish; involucral bracts 4, glabrescent; marginal paleae free, silky.
Shrub, 0.3-1.0 m high. Leaves ericoid, decussate on long twigs or fasciculate on short twigs. Heads solitary on short twigs or racemose on long twigs, pedunculate, with up to 6 flowers per head.
