Perennial. Stem erect, simple, 27–69 cm tall, spreading whitish puberulent. Basal leaves 2–3, long petiolate; petiole 5.5–9.5 (–26) cm long, sparsely spreading puberulent, narrowly sheathed; blade subglabrous adaxially, sparsely puberulent on nerves abaxially, 2.9–4.8 (–7.5) cm long, 2.4–7.8 (–13.8) cm wide, reniform or pentagonal-reniform, base broadly cordate, 3-parted nearly to the middle, median partition broadly obtrapezoid or oblong, undivided or indistinctly 3-lobate, lobes 2–3-crenate-denticulate or entire, lateral partitions obliquely flabellate, unequally lobate. Middle stem leaves absent or 1, occasionally 2, smaller, shortly petiolate; petiole 1–3.5 (–6.5) cm long; blade 1–2 cm long, 3–4.5 (–9.5) cm wide, nearly laciniate, lobules lanceolate-linear. Distal stem leaves bractlike. Raceme elongated, many-flowered, 6–26 cm long, densely somewhat spreading puberulent; bracts leaflike or lanceolate-oblong, 7–14 mm long, sparsely appressed puberulent. Pedicels 7–30 mm long, densely somewhat spreading puberulent; bracteoles distal, lanceolate-oblong, 3.5–10 mm long, 1.2–2 mm wide, sparsely appressed puberulent. Sepals blue or blue-purple, abaxially puberulent, persistent in fruit; upper sepal 5–12 mm long, 4–9 mm wide, obtuse, the spur subulate, 1–2.5 cm long, 1.5–2.5 mm wide at base; other sepals 4–10 mm long, 1.3–7 mm wide. Petals dark brown or black, acuminate, glabrous. Staminode dark brown, limb oblong, 5 mm long, 2 mm wide, 2-cleft and gaping almost halfway, the lobes white barbate, claw 6 mm long. Filaments sparsely pilose or glabrous. Carpels 3; ovaries densely puberulent. Seeds 1.2–2 mm long, dark brown, triangular.

Distribution and habitat:— Delphinium kansuense is distributed in southeastern Gansu and eastern Qinghai, China ( Fig. 6 View FIGURE 6 ). It grows in alpine meadows or scrub at forest margins at elevations of 2700–3000 m.

Phenology:—Flowering in late July to early September; fruiting in middle August to late September.

Additional specimens examined:— CHINA. Gansu: Lianhua Shan, Anonymous 342 (PE), Lanzhou Norm. Univ. Depart. Biol. 527 (PE). Qinghai: Ping’an, Q.E. Yang 9523 (PE), Q.E. Yang & Q. Yuan 386 (PE); reaches of the Datong River, N.M. Przewalski s.n. (collected in 1880) (E), N.M. Przewalski s.n. (collected in 1872) (K, P).

Notes:—The type material of Delphinium crassifolium var. tanguticum includes at least three LE sheets collected by Przewalski from eastern Qinghai [not Kansu (= Gansu) as given in the field records and in the protologue], China. The three sheets kept in E, K and P ( Figs. 2D View FIGURE 2 , 7 View FIGURE 7 ) may also belong to the type material. As no precise collecting date was given in the field records, here we have not included them in the type material. Maximowicz (1889) did not designate type for D. crassifolium var. tanguticum in the protologue, so the three LE sheets should all belong to syntypes ( Turland et al. 2018). Here we designate the LE specimen of N.M. Przewalski s.n. collected on 16 August 1880 (LE01013668; Fig. 2C View FIGURE 2 ), which is relatively complete and matches perfectly the original Latin description, as the lectotype of D. crassifolium var. tanguticum .
