Henry; L. yesoensis (Franchet) Diels; L. yesoensis var. crenifera (Franchet) Diels; L. yesoensis var. pulchella Pampanini; L. yesoensis var. sutchuenensis (Franchet) Diels; Senecillis hodgsonii (J. D. Hooker) Kitamura; Senecio hodgsonii A. Henry; S. yesoensis Franchet; S. yesoensis var. crenifer Franchet; S. yesoensis var. sutchuenensis Franchet.

Stem erect, to 100 cm tall, 3-5 mm in diam. at base, proximally glabrous, distally and synflorescence white arachnoid-puberulent and shortly yellow pilose. Basal leaves petiolate; petiole 10-30 cm, slender, base narrowly sheathed; leaf blade reniform or cordate-reniform, (2-)5-8 × 4.5-13 cm, thick, glabrous, with palmate veins and conspicuous reticulate veins, base cordate, margin triangular-dentate or crenate and ciliate between teeth, apex rounded. Middle to distal stem leaves few, shortly petiolate or sessile, base broadly sheathed; leaf blade reniform, smaller than lower leaves. Capitula 1 to many, solitary or in corymb or compound corymb, branches 6-12 cm, fasciated; leaflike bracts navicular, 2-3 × ca. 1 cm; peduncles 0.5-2.5 cm; supplementary bracts linear-subulate, shorter than involucre. Involucre broadly campanulate, longer than broad, 10-14 × 7-10 mm, outside glabrous or white arachnoid-puberulent, base truncate or rounded; phyllaries 8 or 9, closely imbricate, purplish red, oblong, 3-4 mm wide, brown ciliate, apex broadly triangular, sometimes mucronate; inner phyllaries 2-carinate on convex outside, margin broadly membranous. Ray florets yellow; lamina oblong, 15-25 × to 6 mm wide, apex obtuse and denticulate; tube ca. 4 mm. Tubular florets numerous, extending from involucre, 9-10 mm; tube 2-3 mm. Achenes cylindric, 7-8 mm, ribbed. Pappus reddish brown, as long as tubular corolla. Fl. and fr. Jul-Oct. 2n = 58.

Stream banks, grassy slopes, forest margins; 900-2800 m. ?Anhui, SW Gansu, W Guangxi, NW Guizhou, ?Henan, Hubei, S Shaanxi, N Sichuan, ?Xizang, E Yunnan [Japan, Russia (Far East), ?Vietnam].

One of us (Illarionova) believes that Ligularia hodgsonii is absent from China. Chinese specimens determined as L. hodgsonii belong to L. dentata. Ligularia hodgsonii differs from L. dentata by the structure of synflorescence (indeterminate (acropetal) raceme with long peduncles in L. hodgsonii vs. (basipetal) corymb in L. dentata) and by the navicular membranous bracts near each peduncle. According to Illarionova, L. hodgsonii occurs only in Japan and Russia (Far East).
