Hypericum pseudohenryi N. Robson


Description from Flora of China

Shrubs, 0.7-1.7 m tall; branches erect to spreading. Stems 4-angled and ancipitous in first year, then terete, stout; internodes 0.8-6 cm, shorter than to exceeding leaves. Leaves with petiole 0.5-1 mm; blade ovate or ovate-oblong to lanceolate or lanceolate-oblong, 2-6.6(-8) × 0.5-3.5 cm, thickly papery, abaxially paler or somewhat glaucous; laminar glands dots and short streaks; abaxial glands densest or present only near midvein; main lateral veins 2- or 3-paired, the upper forming distinct undulating intramarginal vein, tertiary reticulation lax, obscure; base narrowly to ± broadly cuneate, apex rounded or rarely apiculate-obtuse. Inflorescence 1-7(to ca. 25)-flowered, from apical node, nearly flat-topped; bracts narrowly lanceolate to leaflike, persistent. Pedicels 4-11 mm. Flowers 3-5.5 cm in diam., stellate to shallowly cupped; buds ovoid-pyramidal, subacute. Sepals erect to outcurved, subequal, broadly to narrowly ovate-oblong, 6-9(-13) × 3-7 mm, laminar glands lines, margin entire or minutely denticulate toward apex with narrowly hyaline margin, apex acute to subacuminate or obtuse. Petals golden yellow, sometimes becoming reflexed, obovate, 1.6-3.3 × 1-2 cm, 2.5-3 × as long as sepals; apiculus obtuse; margin eglandular, entire or irregularly eroded-denticulate. Stamen fascicles each with ca. 40 stamens, longest 1.4-2 cm, 0.75-0.85 × as long as petals. Ovary ± broadly ovoid, 5-9 × 3.5-6 mm; styles 5.5-11 mm, somewhat longer than ovary, free, suberect to divergent, outcurved near apex. Capsule ovoid-conic to ovoid, 1.2-1.7 × 1-1.4 cm. Seeds dark orange-brown, 1.5-2 mm, narrowly carinate; testa linear-foveolate. Fl. Jun-Sep, fr. Sep-Nov.

The area of distribution of Hypericum pseudohenryi overlaps that of the closely related H. forrestii, and plants with characters intermediate between these species have been found.

Pinus forests, thickets, dry grassy or stony slopes; 1400-3800 m. SW and W Sichuan, NE and NW Yunnan.
