Leaves linear-acicular, subterete-canaliculate, (18)28–50 (60) × 0.5–1 cm., mucronate, glabrous (floccose only when very young), straight or slightly flexuose, usually with axillary short shoots or leaf-fascicles and tufts of floccose hairs.
Much-branched, bushy annual herb with a slender taproot, c. 0.27–0.6 m. high; stem and branches slender and rather wiry, terete, young parts green and more or less floccose to sublanate at least when young, usually soon glabrescent.
Bracts lanceolate, 4–5 mm. long, glabrous or somewhat floccose, the darker midrib excurrent in amucro, more or less patent after fruit-fall.
Inflorescence elongating, (to c. 30 cm. or more but often less), the axis glabrous to more or less floccose; partial inflorescences finally distant (separated by 1.5–2.5(3) cm.), varying from 1–3 flowered as in the generic description, the lateral brushes of hair whitish.
Fruiting partial inflorescence a fluffy ball c. 1.5–2 cm. in diam.
Bracteoles of partial inflorescence, deltoid-lanceolate, 4–5 mm. long, rather similar to the bracts but more deeply concave basally to accommodate the sterile flowers, glabrous to more or less floccose, at anthesis.
Fruit oblong-ovoid, c. 3.5 mm. long, smooth and glabrous throughout; seed c. 3.25 mm. long, brown, smooth and shining.
