|1||Leaves elliptic to ± obovate or oblong, margins flat or recurved; branchlets often spinose; bracts enclosing base of hypanthium, not distinctly constricted in lower half in fruiting stages||2|
|Leaves ± terete, margins strongly revolute; branchlets not spinose; bracts usually below hypanthium, hypanthium constricted in lower half in fruiting stages. Leaves mostly 2–6 mm long (rarely to 10 mm). Flowers 2–3 mm long, crowded at end of lateral branches, white-tomentose with short stellate and longer simple hairs. Hypanthium and sepals turning reddish with greyish hairs in fruiting stages||var. floribunda|
|2||Flowers 2–4 mm long, sepals not spreading, 1–2 mm long, ± equal to hypanthium, not ridged. Leaves 2–5 mm long, elliptic to oblanceolate. Flowers sessile, few and scattered or in clusters of 2–10 at end of branches. Hairs on hypanthium and sepals shortly stellate||var. amara|
|Flowers 4–6 mm long, sepals often spreading, 1–2 mm long, less than half as long as the hypanthium, ridged. Leaves 3–6 mm long, mostly obovate to oblong, sometimes ovate. Hairs on hypanthium shortly stellate with longer simple hairs on sepals. Flowers shortly pedicellate, solitary or in few-flowered leafy clusters|
