Characteristics

Many-stemmed, slender, erect shrubs, 1.2-2.0 m high. Old steins displaying anomalous secondary growth, brown-grey; young shoots grey, internodes either short, densely leafy or relatively long with leaves scattered; brachyblasts short-lived. Leaves alternate, rarely opposite, sessile on cushion-like thickenings on stem, linear to narrowly lanceolate or obtuse-triangular, 3-30 x 0.5-1.5(-2.0) mm, entire, succulent, permanently grey-felty, adaxially flattened, concave towards base, abaxially convex, apex acute. Capitula heterogamous disciform, racemose or paniculate, 2.5-4.8 mm long, sessile to distinctly pedunculate; peduncles 0-15 mm long, felty. Involucral bracts 4, 3 x 2 mm, central part herbaceous, green, red-purple towards membranous margin, abaxially felty, 2 slightly keeled, 2 laterally flattened, margins enveloped by the two keeled bracts. Paleae: those of marginal florets connate into cylindrical sheath, basally slightly globose, apices and abaxially long-lanate, hairs septate; those of disc florets lanceolate to linear, 1.5-2.0 mm long, apices fringed, abaxially lanate, sometimes absent in central florets. Marginal female florets 1-3; corolla white to pink, obovate, constricted around style; narrowed part very short. Style almost totally exposed, cylindrical, forked; style branches flattened, linear, up to 1 mm long, apices acute. Ovary (and cypsela) ovoid-oblong, abaxially densely lanate, slightly flattened, 3 x 2 mm. Seed ovoid, laterally compressed, 1.5-2.3 mm long. Disc florets 4-21, functionally male with sterile ovary; corolla ±3 mm long, widening distally, glandular abaxially, yellow-green to yellow with purple-red margins, rarely entirely purple-red. Style cylindrical, unbranched, apex broad, with sweeping hairs. Stamens 5, exserted at maturity. Receptacle after anthesis with dense, white, long-hairy indumentum between involucral bracts and connate marginal paleae.
More
Slender, erect shrub, 1.2-2.0 m high. Leaves alternate, rarely opposite, linear to narrowly lanceolate or obtuse-triangular, entire, succulent, permanently grey-felty. Capitula disciform, racemose or paniculate, sessile to very shortly pedunculate (in var. racemosus); involucral bracts 4 with red-purple, membranous margins. Receptacle paleate, those of ray florets connate, hairy on outside, those of disc florets free. Marginal female florets (1)2, white to pink. Disc florets (4-)7-9, widening upwards, yellow-green to yellow with purple-red margins. Flowering time no flowering specimens in PRE from EC, but June-Sept. (Nov.) according to literature. Pappus absent. Cypselae ovoid-oblong, slightly flattened, densely lanate.
Slender, erect shrub, up to 1.5 m tall. Leaves alternate on flowering stems and short shoots, linear-lanceolate, 3-30 mm long, grey-or silver-felted. Flowerheads racemose-paniculate, nearly sessile or on peduncles up to 15 mm long, disciform, 2.5-5 mm long, white to pink; involucral bracts 4, felted; marginal paleae connate into a tube, woolly.
Silvery silky shrub to 1.5 m. Leaves linear, alternate, sometimes tufted. Flower heads radiate, appearing discoid, solitary in leaf axils, forming long racemes, pink.
