DIAGNOSTIC DESCRIPTION
Perennial herb 0.15–0.5 m tall, erect to ascending, sometimes rooting, with stems few, unbranched below inflorescence or (very rarely) branched throughout when ascending (‘var. latronum’). Stems terete, eglandular, not glaucous; internodes 13–30 mm, usually shorter than leaves. Leaves sessile to subamplexicaul, spreading; lamina 20–50 × 8–15 mm, all triangular-lanceolate or upper triangular-ovate, paler beneath, chartaceous, very rarely with setaceous hairs beneath (galled? - ‘H. setiferum’); apex subacute, margin plane to recurved, entire, base cordate to rounded; venation: 3–4 pairs of main laterals from lower half of midrib, branched, with lax tertiary reticulation; laminar glands pale, rather sparse to almost absent and sometimes a few black (‘subsp. urumovii’); intramarginal glands black, dense to irregular or rarely sparse (‘H. pseudotenellum’). Inflorescence 3–25-flowered from 1–3 nodes, rather lax, without lower branches or rarely with one to numerous flowering branches (see above), the whole broadly conic to corymbiform or concave; pedicels 1– 1.5 mm or (central flower) to 6 mm; lower bracts reduced-foliar, ovate, entire; upper bracts and bracteoles linear, black-glandular-fimbriate. Flowers c. 20 mm in diam., stellate; buds broadly ellipsoid, rounded. Sepals 5, subequal, not or very shortly united, 3.5–6.5(–8) × 1.5–3 mm, oblong-elliptic to lanceolate, subacute, glandular-fimbriate; veins: 3, unbranched, becoming prominent in fruit; laminar glands pale, shortly striiform to punctiform; marginal glands black, on fimbriae and sometimes 1–2 intramarginal. Petals 5, bright? yellow, not tinged red, c. 10(–16?) × 3.5 mm, 2–3 × sepals, narrowly obovate, rounded; laminar glands pale, striiform and sometimes a few black, distal; marginal glands black, dense, sometimes with a few distal on cilia. Stamens c. 42–55, longest 8–9 mm, c. 0.8 × petals. Ovary 2.5–4 × 1.3–2 mm, ± narrowly ovoid; styles 5–6 mm, 1.5–2 × ovary. Capsule 9–11 × 5–6 mm, ovoid; valves with globose amber vesicles. Seeds orange-brown, 1.3 mm; testa ribbed-scalariform.
