Hypericum capitatum Choisy

Perennial herb, 0.15–0.50 m tall, glabrous, erect from taproot or decumbent at base, branching at base and from all stem nodes, sterile shoots not distinct. Stems eglandular or with ± numerous amber gland dots, not prominent; internodes 10–50 mm, longer to shorter than leaves. Leaves sessile, 8–28 × 1.5–3.5 mm, spreading to ascending, ± glaucous; lamina linear to narrowly oblong, apex subapiculate or rounded, margin sometimes revolute, base rounded; 1-veined or with 1–2 pairs of lateral veins from lower 1/4 of midrib; laminar glands pale, numerous, punctiform, marginal glands spaced. Inflorescence ∞-flowered, very broadly pyramidal to subcorymbiform, subcapitate in bud, 30–70(–100) mm long, with lateral cymules 3–7-flowered, mostly monochasial, sometimes with 1–2 pairs of lower branches; lower bracts linear, entire, upper bracts and bracteoles ovate with sessile black marginal glands. Flowers 8–12 mm in diam., with petals eventually deflexed; buds ellipsoid, obtuse to rounded. Sepals equal, almost free to united, green to dark red, 1.5–2.5 × 0.7–1 mm, oblong to to ovate-lanceolate, acute to obtuse or rarely rounded; veins 3, sometimes slightly prominent; margin regularly glandular-denticulate or with regular subsessile glands, glands black, globose to ellipsoid; laminar glands pale, in usually 2 continuous or interrupted lines. Petals rich yellow to orange-red or blood red or crimson, 5–7 × 2–3 mm, oblanceolate, long-unguiculate, rounded, margin with subsessile black glands towards apex; laminar glands pale, few, distal, punctiform. Stamens c. 35, longest c. 6 mm, equalling petals; filaments yellow to crimson. Ovary c. 1.5–2 × 0.7–1 mm, ovoid, not rostrate; styles yellow to crimson, 3–4 mm, 2 × ovary. Capsule 4–7 × 2.5–4 mm, broadly ovoid to subglobose, not or scarcely rostrate; vittae narrow. Seeds dark brown, 1–1.5 mm long.
