Hypericum galioides

Shrubs, erect, forming rounded clumps, 5–15 dm. Stems: internodes 6-lined at first, soon 4-lined, then terete. Leaf blades narrowly oblong-elliptic or oblanceolate to linear, 15–32(–37) × 1–7 mm, base articulated, attenuate, margins recurved to revolute, apex rounded to acute, midrib obscurely branched. Inflorescences narrowly cylindric, 3–15-flowered from apical node, with (1–)3–5-flowered dichasia from 3–4 proximal nodes, sometimes with additional flowering branches. Flowers 9–14 mm diam.; sepals deciduous, not enclosing capsule, 5, oblanceolate-spatulate to linear, subequal or equal, 3.5–6.5 × 0.5–1.5 mm; petals 5, bright yellow, obovate-oblanceolate, 5–9 mm; stamens deciduous, 60–120; ovary 3-merous, placentation parietal. Capsules narrowly ovoid-conic, 4.5–6 × 2.5–3.5 mm. Seeds narrowly carinate, 0.7–0.8 mm; testa finely reticulate. 2n = 18.
