Hypericum orientale L.

Perennial herb 0.07–0.45 m tall, erect to decumbent and sometimes rooting at base, with stems numerous, spreading and branching from taproot, otherwise rarely branching below inflorescence. Stems narrowly 2-lined, eglandular or with few reddish or rarely black glands on lines or usually scattered; internodes 3–20 mm, shorter than leaves. Leaves sessile ascending to erect; lamina 10–40 × 2–5(–10) mm (excluding auricles), narrowly oblong or narrowly elliptic-oblong to linear or oblanceolate, concolorous, chartaceous; apex rounded, margin very shallowly glandular-denticulate, base narrowly cuneate with paired gland-fringed auricles; venation: 3 main veins from lower ¼ of midrib, not visibly branched; laminar glands pale, punctiform, dense; marginal glands pale, flat-topped, on denticuli. Inflorescence 3–c. 21-flowered, from 1– 3(4) nodes, often with flowering branches from 1–3(4) nodes below, the whole obpyramidal to broadly pyramidal or cylindric; bracts and bracteoles elliptic or oblong to linear, auriculate and gland-fringed. Flowers 20–c. 40 mm in diam.; buds ellipsoid, rounded. Sepals unequal, imbricate, almost free, 4–7 × (1.5–)2–4.5 mm, narrowly to broadly oblong or elliptic to obovate-spathulate or obovate, obtuse to rounded, regularly shortly glandular-denticulate; veins 5(3), not branched; laminar glands pale, linear to punctiform; marginal glands pale, on denticuli. Petals bright yellow, not tinged or veined red, 10–18 × 2.2–4.5 mm, c. 2.5 × sepals, oblanceolate, rounded, entire; laminar glands pale, linear (proximal) to punctiform (distal); marginal glands pale, lateral and apical, immersed. Stamens 30–45, ‘3’-fascicled, longest 7–13 mm, c. 0.07 × petals; anther gland amber. Ovary c. 2–4 × 1.5–2 mm, narrowly ovoid; styles 3, 5–8 mm, c. 2–2.5 × ovary, spreading to ascending. Capsule 8–11 × 3.5–4.5 mm, narrowly ovoid to ovoid-pyramidal, 1.5–2 × sepals, with numerous longitudinal vittae sometimes intermittently slightly swollen. Seeds mid brown, 1–1.5 mm; testa foveolate-scalariform.
