Hypericum nummularium L.

Perennial herb, 0.05–0.35 m tall or long, glabrous, caespitose to diffuse with stems erect to ascending or decumbent and rooting from scarcely woody base, without axillary shoots. Stems terete, green or sometimes partly reddish, eglandular; internodes 10–25 mm long, exceeding leaves. Leaves c. 1 mm petiolate, thinly coriaceous, glaucous beneath, 4.5–23 × 3–17 mm, elliptic to circular, apex obtuse to rounded, margin plane, base rounded to truncate or subcordate, with 3 pairs of ascending lateral veins; laminar glands pale, punctiform, rather dense, obscure, absent from basal area; intramarginal glands pale (dried contents sometimes appearing black), rather small, dense, usually with 1–2 apical black glands beneath. Inflorescence 1–8-flowered from 1–2 nodes, corymbiform, ± dense, 10–40 mm long, with lateral branches straight, widely ascending; cymules 1–2(–4)-flowered, branching monochasial, without flowering branches below; bracts and bracteoles elliptic to linear, with black glands sessile or on denticles or cilia, base sometimes glandular-subauriculate. Flowers 15-30 mm in diam., petals erect after flowering; buds subglobose to ellipsoid, rounded. Sepals subequal to unequal, free, imbricate, 4–6 × 2–3 mm, oblong or elliptic to obovate, rounded to subobtuse; veins 3, branching; margin black-glandular-denticulate, sometimes with subapical black gland; laminar glands pale, linear to sometimes punctiform. Petals pale? yellow, sometimes veined red, 8–18 × 2–5 mm, 2–3 × sepals, narrowly elliptic to oblanceolate; margin distally or mostly black-glandular-ciliate; laminar glands absent. Stamens c. 40–55, longest 7–12 mm, c. 0.7–0.9 × petals; filaments yellow. Ovary 2.5–5 × 1.5– 3.5 mm, ovoid; styles 4–6 mm, 1.2–1.6 × ovary. Capsule 4–8 × c. 2.5–5 mm, ovoid. Seeds “brownish”, c. 1 mm long (“pale, very elongated”); testa “almost smooth” (fide Stefanoff, 1931).
