Characteristics

A shrub 1-3 ft. high; branches pale, scabrid with small hook-like short setae. Leaves tufted, or if scattered then alternate, acicular, acute, glabrous except for a row of short white teeth on each infolded margin, 1-1.3 cm long, about 1 mm thick, much shorter than the flower-heads. Heads terminal, solitary or often up to 5 in a corymb, well exserted from the leaves, pedunculate, the peduncles bearing smaller leaves, subeampanulate, about 1.5 cm long and the same in diameter. Involucral bracts about 5-seriate, shorter than the flowers; the outermost linear or linear-lanceolate, acute, about 3 mm long; the intermediate lanceolate, acute, with a distinct keel in the upper half; the innermost linear-lanceolate, about 1 cm long, acute; all straw-coloured or brownish straw-coloured and shortly and closely ciliate, otherwise glabrous. Receptacle setose and deeply pitted. Corolla yellow, 1 cm long, gradually widened upwards, very sparingly pubescent; lobes linear-lanceolate, acute, 2 mm long. Achenes 3-4 mm long, flattened, glabrous and shining. Pappus sub-uniseriate, connate into a ring at the base, about 1 cm long, whitish straw-coloured.

A shrub; branches strigose-pubescent. Leaves dense, clustered or alternate, acicular, acute, subterete, 1-2 cm long, fleshy, with a few cilia on the lower part or sometimes nearly glabrous. Heads corymbose at the ends of the principal branches, each terminating a short lateral branch, campanulate, about 2 cm long and about 1.5 cm in diameter. Involucral bracts 5-6-seriate, exceeding the flowers, greenish when dry, all linear or linear-lanceolate, conspicuously tailed-acuminate, and very prominently ribbed, very slightly ciliolate, otherwise glabrous. Receptacle honeycombed. Corolla green? about 1 cm long, ribbed and sparsely puberulous in the lower part, gradually widened from the middle upwards; lobes lanceolate, subacute, 1.5 mm long. Achenes glabrous, somewhat flattened and elliptic when ripe, 5 mm long, smooth and shining, with thickened lighter coloured margins. Pappus about 8 mm long, 1-seriate, straw-coloured, the setae shortly pilose and connate into a ring at the base.
Slender, aromatic shrub, up to 2 m high. Leaves tufted, or if scattered, then alternate or opposite or subopposite in var. laevigata, linear to filiform, long, acute, glabrous except for ciliate margins (short white teeth) (var. longifolia), setose all over or totally glabrous (var. laevigata), glandular. Capitula discoid, 1-few at branch tips, pedunculate; involucral bracts in many rows, imbricate, linear to linear-lanceolate, acute, straw-coloured, shortly and closely ciliate, shorter than florets. Florets yellow. Flowering time Oct. Pappus of straw-coloured, subplumose bristles, outer more slender than inner, basally connate in a ring. Cypselae elliptic, flattened, with thickened margins, glabrous and shining.
Shrub, 0.5-3.0 m high. Leaves clustered or alternate, densely set, long-acicular, subterete, apex acute, succulent, margins sometimes ciliate in lower part. Capitula discoid, corymbose at ends of branches; involucral bracts in many rows, imbricate, longer than florets, linear or linear-lanceolate, tailed-acuminate, margins slightly ciliate. Florets greenish yellow. Flowering time Sept.-Nov., Feb. Pappus straw-coloured, plumose, united basally into a ring, outer more slender than inner. Cypselae elliptic, flattened, glabrous, margins thickened.
Slender, aromatic shrub, up to 1 m tall. Leaves alternate, in tufts or scattered, linear to filiform, long, acute, minutely bristly all over or glabrous, occasionally only margins ciliate with short white teeth.

Cypselas glabrous; pappus straw-coloured.
