DIAGNOSTIC DESCRIPTION
Perennial herb, 0.15–0.6 m, erect, branching at base and from all stem nodes; sterile shoots not distinct. Stems with ± numerous small amber or reddish gland dots, not prominent; internodes 15–40 mm, exceeding leaves. Leaves sessile, spreading to ascending, glabrous and scarcely glaucous or undulate-papillose above; lamina 8– 22 × 1–3 mm, linear, apex rounded, margin often revolute, base cuneate; 1-veined or with 1–3 pairs of lateral veins from lower 1/2 to 2/3 of midrib; laminar glands pale, numerous, punctiform, marginal glands spaced. Inflorescence ∞-flowered, broadly to narrowly pyramidal or cylindric, 50–200 mm long, with lateral cymules 3–13-flowered, sometimes with up to 7 pairs of lower branches; bracts and bracteoles linear to narrowly oblong, the upper sometimes with black marginal glands. Flowers 10-16 mm in diam., with petals eventually deflexed; buds broadly ellipsoid to globose, rounded. Sepals equal or subequal, 1/4–1/2 united, 1.5–3 × 0.7– 1.2 mm, oblong to ovate-oblong, rounded to obtuse or rarely acute; veins (1)3(5?), becoming slightly prominent; margin regularly glandular-denticulate, glands black, globose; laminar glands pale, usually in 2 continuous or interrupted lines. Petals chrome? yellow, not red-tinged, 6–8 × 3–4.5(–6) mm, oblanceolate, long-unguiculate, rounded, margin black-glandular-ciliate or with sessile black glands, denser towards apex; laminar glands pale, punctiform. Stamens 35–45, longest c. 8 mm, equalling petals; filaments yellow. Ovary 1.7–2.5 × 1.5–2 mm, broadly ovoid to subglobose, shortly rostrate; styles 3–4 mm, 1.6 × ovary. Capsule 4–6 × 3–4.5 mm, broadly ovoid to subglobose, shortly rostrate; vittae narrow. Seeds dark brown, c. 1.5 mm long.
