本种极近岷江金丝梅H. henryi Levl. et Van. subsp. uraloides (Rehd.) N. Robson
有时确难予区分，但前者有多叶的枝条、较宽的叶片和萼片而不同。

匙萼金丝桃 chi e jin si tao

Hypericum patulum Thunberg var. attenuatum Choisy; H. patulum var. uralum (Buchanan-Hamilton ex D. Don) Koehne; Norysca urala (Buchanan-Hamilton ex D. Don) K. Koch.

Shrubs, 0.3-2 m tall; branches arching, often frondose. Stems 4-lined or 4-angled and strongly ancipitous when young, eventually 2-lined or terete; internodes 0.5-2 cm, shorter than leaves. Leaves with flat petiole 0.5-1 mm; blade lanceolate or when older sometimes ovate, 1-4 × 0.4-2.4 cm, thickly papery, abaxially ± densely glaucous; laminar glands streaks (toward midvein) and dots; abaxial glands usually ± dense; main lateral veins 3-paired, tertiary reticulation scarcely visible; base narrowly or rarely broadly cuneate, apex acute to rounded-apiculate. Inflorescence 1-3(-10)-flowered, from 1 or 2 nodes, nearly flat-topped, with short terminal internode, often with 1-3-flowered branches from middle of stem; bracts deciduous, narrowly oblong. Pedicels 3-7 mm. Flowers 1.5-3 cm in diam., ± deeply cupped; buds broadly ovoid to globose, apex obtuse to rounded. Sepals erect, subequal to unequal, oblong or elliptic to oblong-spatulate, 3.5-6(-9) × (1-)2-5(-6.5) mm; laminar glands lines, margin entire with narrowly hyaline margin, apex rounded or very rarely obtuse. Petals golden to deep yellow, not tinged red, broadly obovate to subcircular, 0.9-1.8 cm × 5-12 mm, 2.5-3 × as long as sepals; margin entire, eglandular; apiculus rounded or obsolete. Stamen fascicles each with 40-60 stamens, longest 4-6(-8) mm, 0.25-0.5 × as long as petals. Ovary broadly ovoid to globose, 3-5 × 2.5-3 mm; styles 2.5-4.5 mm, 0.6-0.9(-1) × as long as ovary, free, erect and divergent toward apex or wholly outcurving. Capsule subglobose or more rarely broadly ovoid, 7-11(-13) × 7-11 mm. Seeds dark brown, 0.4-0.6 mm, scarcely carinate; testa linear-foveolate. Fl. Jul-Sep, fr. Aug-Oct. 2n = 20.

Dry open habitats, sometimes in thickets and by streams; 1500-3600 m. Xizang (Moindawang, Zayü), NW Yunnan [Bhutan, NE India, N Myanmar, Nepal, Pakistan].

Hypericum uralum is sometimes very similar to H. henryi subsp. uraloides but can usually be distinguished by the frondose stems and broader leaves and sepals.
