Small, rather delicate, tufted annual. Leaves few (usually fewer than the scapes), linear-acute, 1-5 cm long, 0.3-1.7 mm wide, tapering to a fine point, light green, often reaching the flowering heads. Scapes 4-50, radiating to form a dome, 2-13 cm long, 0.2-0.3 mm thick, 3-or 4-ribbed; sheaths 0.5-1.5 mm long, usually shorter than the leaves, obliquely split with a subacute limb. Heads ± spherical to ovoid, 1.5-3 mm in diameter, dull grey to blackish, appearing rather loose and untidy; receptacle glabrous to softly hairy. Involucral bracts as wide as the head, elliptic to narrowly obovate, 1.4-1.6 mm long, ascending, glossy, pale-grey to whitish. Floral bracts oblanceolate-obovate, 1.2-1.5 mm long, glabrous, thin, dry, subacute to shortly acuminate, flushed grey with upper ones darker. Flowers ±1 mm long. Male flowers: sepals 3, united below the middle, ±0.8-0.9 mm long, the free tips triangular, glabrous; petals rudimentary; anthers ±0.15 mm long, black. Female flowers: sepals 3, free, variable, subequal, narrowly lanceolate to lanceolate, 1-1.2 mm long, concave but not keeled, acute or acuminate, the margins glabrous or with a few short hairs or occasionally with long hairs: petals 3, free, subequal, linear, up to ±1 mm long, rudimentary glands usually present on at least the 2 smaller petals. Seeds ellipsoid to broadly ellipsoid, ±0.35 mm long, brown, glossy; seed coat almost smooth, very faintly net-like.
Caespitose, dome-shaped herb, rosulate-hydrophyte, 20-90 mm high. Leaves light green, linear-acuminate. Capitula dull blackish grey, loose, oblong-globose, ± 10 mm long; peduncle 45(-100) mm long; involucral bracts ± half as long as capitulum, reflexed with age, scarious; receptacle glabrous or rarely with few hairs. Female flower on short pedicel; sepals 3, free, subequal, lanceolate, not keeled, not winged, half folded, margins usually glabrous; petals 3, free, linear, subequal, smaller petal usually with rudimentary glands; ovary sessile, 3-locular; style typical. Male flower: sepals 3, connate below middle, free lobes triangular; lobes minute with apical black gland; petals rudimentary, grey; stamens 6; anthers black. Flowering time Feb. Fruit a trilobed capsule; locules globose.
Small tufted, dome-shaped annuals 20-100 mm tall. Leaves few, linear-acuminate. Capitula oblong-globose, c. 3 mm long, dull greyish black, on peduncles up to 45(-100) mm long; involucral bracts c. 10, pale, about half as long as capitulum, reflexed with age; floral bracts smaller, dark; receptacle conical, glabrous or rarely with a few stray hairs. Female flowers on short pedicels; sepals 3, ovate, concave, half-folded, dark; petals linear, acute, glabrous; ovary sessile, 3-locular; style typical. Male flowers: sepals 3, obliquely fused below; petal lobes minute with an apical black gland; stamens 6, with black anthers. Capsule trilobed, locules globose; seed ellipsoid, smooth, shiny, but reticulate and muricate under 400x magnification.
Dome-shaped annuals up to 130 mm tall. Leaves linear-acuminate, c. 10 mm long. Capitula oblong-globose, 2-3 mm in diam., dark grey on peduncles 20-100 mm long; involucral bracts c. 10, large, pale, acute, floral bracts smaller, dark, but much larger than sepals; receptacle conical with some long hairs. Female flower: sepals 3, c. 1-2 mm long, conchiform, not keeled, enclosing rest of flower, ovate-acuminate, blackish, margin whitish, bearing some coarse setae; dorsal sepal somewhat smaller; petals 3, narrowly spathulate, somewhat longer than sepals; ovary 3-locular; style short with 2 longer stigmas. Male flower typical; anthers black. Capsule 3-lobed, seeds ovoid, minutely reticulate and muricate.
Small, tufted, dome-shaped annual, up to 100 mm high. Leaves few; blade distinctly flattened, usually < 2 mm wide and < 50 mm long, tapering to fine point. Flowers: scape slender; heads dark with paler involucral bracts; bracts and sepals broadly ovate, obtuse; receptacle usually quite glabrous; stigmas 3; sepals 3, with a smooth margin; petals grey to black. Seeds almost smooth, very faintly net-like.
