Type:— China . Beijing : Miyun District, Baidaoyu, Heluodian, near the river in valley, 8 May 1972 , Anonymous Miyun-065 ( holotype , PE-00990057). Fig. 5 . Image of the holotype available at http://www.cvh.ac.cn/en/spm/ PE /00990057. Perennial herb, with short erect taproot bearing 5–10 annual flowering stems branched in the upper part ( Fig. 6A ). Stems 30–55 cm tall, covered with simple and glandular hairs. Leaves thick in texture, adaxially dark green with brighter nerves, greyish abaxially. Basal leaves rosulate, 18–22 cm long, persistent, ternate or 2-ternate; petioles 10–15 cm long, covered with simple and glandular hairs; laminae glabrous, margins with solitary simple hairs; leaflets 3- lobate, obovate or broadly ovate, almost glabrous above, more or less pubescent beneath, with 2–7 rounded teeth. Cauline leaves 5–9 cm long, ternate or 2-ternate; petioles 4–5 cm long, with simple and short glandular hairs; laminae with simple and glandular hairs adaxially; terminal lobes obovate or orbicular with 3–4 rounded teeth. Bracts 0.8– 2.8 cm long, ternate, short-petiolate (petioles 0.3–0.5 cm long); leaflets oblong, both sides covered with simple and glandular hairs. Inflorescence 5–10-flowered. Flowers 2-coloured, inclined to pendulous, 1.2–2.1 cm long, 1.2–1.5 in diameter when opened ( Figs. 3E, F ; 6E ). Sepals spreading or perpendicular to the floral axis, ovoid, pale blue or lilac-blue, 0.5–0.8 cm long, 0.2–0.3 cm wide, acute to obtuse at apex ( Fig. 6B ), margins with simple hairs. Petals purple to violet, 0.9–1.3 cm long, laminae 0.4–0.5 cm long, 0.3–0.35 cm wide, parallel to floral axis, truncate, slightly ventrally folded, shorter than sepals and spurs; spurs thin, basally not inflated, apically hooked or slightly bent ( Fig. 6C ), 0.5–0.7 cm long, puberulent. Stamens 1.0– 1.5 cm long, long-exserted (to the extent of 0.7 cm ). Anthers yellow ( Fig. 3E, F ). Follicles 5, 1.8–2.4 cm long (including styles 1.2–1.5 cm long), glandular pubescent, divergent ( Fig. 6D ). Seeds 1.8–2.0 × 0.7–0.9 mm wide, with tuberculate surface ( Fig. 4F ). Habitat: —Moist, often shaded and rocky places; ravines. Phenology: —Flowering April–May; fruiting May–July. Conservation status: —The same as in A. xinjiangensis (see above).

Notes: — Aquilegia hebeica was usually identified as A. viridiflora var. viridiflora or A. viridiflora var. atropurpurea (Willdenow) Finet & Gagnepain (1904: 413) [≡ A. atropurpurea Willdenow (1809: 577) ] or as A. yabeana (especially in the fruiting stage due to robust stem and leaves). Despite some differences in the reproductive parts, e.g. flower colour or sepal dimensions ( Table 2 ; Figs. 3C–F , 6E–G ), A. hebeica is related to A. viridiflora and A. kamelinii , and we include it in A. sect. Viridiflorae Friesen (1989: 79) . The representatives of this section (as well as those of A. sect. Glandulosae ) are characterized by the tuberculate (papillate) seed surface ( Fig. 4F–H ), which are not observed in any other Aquilegia species ( Figs. 4 , 7 ). Aquilegia atropurpurea is merged with A. viridiflora (e.g. Bulavkina 1937) having the same morphological characters (except flower colour) and distribution area. This taxon needs further investigation. The field studies show that the flower colour in A. atropurpurea may depend on the ecological conditions.
