Characteristics

Perennial herb, with a thick woody rootstock producing numerous simple or sparsely branched annual stems, erect or spreading and ± decumbent, 30–100(–150) cm. long, glabrous or pilose with long spreading hairs.. Leaves subsessile, linear-lanceolate, or ovate on short flowering stems (10–15 cm. high) produced after burning and often tinged with red, to 4(–5) × 1(–1.5) cm., base abruptly cuneate to rounded, apex shortly apiculate, margin narrowly cartilaginous, sometimes ± revolute, and often minutely toothed, glabrous or with some long spreading hairs on the lower surface especially along the midrib, rarely with a few on the upper surface; petiole to 1 mm. long, flattened, with a short tuft of hairs in the axil.. Cymes axillary and in (3-)5(–6)-branched umbels around a terminal ♂ cyathium, with primary rays to 7 cm. long, forking ± 3 times; bracts sessile, deltoid to subcircular, ± 1.5 × 1.5 cm., longer below the umbel, apex acute to rounded, base with a tuft of hairs on the upper surface and sometimes a few hairs on the lower surface.. Cyathia sessile, glabrous, or pilose with spreading hairs, sometimes sparsely so, ± 3.5 × 4.5 mm., with broadly cup-shaped involucres; glands 4–6, spreading, circular to transversely oblong, 1.5–3 mm. broad, yellow; lobes rounded, 1 mm. long, densely ciliate on the inner surface.. Male flowers: bracteoles fan-shaped, densely ciliate; stamens 4.5 mm. long.. Female flower: ovary tuberculate, usually densely so, glabrous or pilose; styles 3 mm. long, joined to nearly halfway, erect, spreading, bifid for 1/3.. Capsule exserted on a pedicel to 6 mm. long, shallowly 3-lobed, ± 5 × 6.5 mm., densely to sparsely covered with large fleshy tubercles, occasionally almost smooth, glabrous or fairly sparsely pilose with long spreading hairs, usually tinged reddish.. Seeds ovoid, slightly compressed, ± 2.5 × 2 mm., smooth, greyish brown; caruncle 1 mm. across, cream.
