Morphology General Habit
Erect to ascending, slender succulent annual or short-lived perennial, branching above the base; stems up to 15(–28) cm high, rather stiffly ascending.
Morphology Leaves
Leaves alternate, spaced, linear-terete, 9–25 mm long, 1–2 mm wide, sharply acute; axillary hairs in long shaggy tufts, sometimes indistinct, each axil also with 2 longer, brownish, hair-like scales with falcately-curving bases (these sometimes indistinct).
Morphology Reproductive morphology Inflorescences
Flowers in terminal clusters of 3–6 or more, encircled by ± 8 involucral leaves enclosing dense woolly hairs, opening in the morning; involucral leaves longer than the cauline leaves, very variable in length, up to 30 mm long, slightly to much exceeding the flower cluster, spreading, finally slightly downturned.
Morphology Reproductive morphology Flowers
Sepals 3–4.5 mm long, rounded on the back, keeled towards the acute apex with a slight crest; petals 5, usually bright red, occasionally orange-red, rose-pink or rarely yellow, 2.5–8 mm long, obovate-oblong, obtuse to acute; stamens (5–)8–13(–19); stigma (3–)4–5-branched.
