Description.

Perennial. Rhizome, short and stout, roots fascicled, fleshy, somewhat fibrous. Stems erect, branched above, 7–52 (– 90) cm tall. Basal leaves 2–8, long petiolate; petioles 5–20 cm long; blade glabrous adaxially and abaxially, occasionally purplish-red on the back, 2–5 cm long, 4–8 cm wide, palmately 3 - parted to nearly 3 / 4–9 / 10 of the way to the base; abaxially pale green, occasionally purplish-red; crenate, serrate or irregularly doubly spinose-serrate; central segment broadly obovate, distally shallowly 3 - lobed, base cuneate, apex obtuse-rounded; lateral segments oblique-reniform, rhombic-rounded or ovate-lanceolate, often 2 - lobed. Cauline leaves reniform-rounded, 3 - parted nearly 4 / 5 of the way to the base, segments obovate to ovate-lanceolate. Inflorescence 2–3 - dichotomously branched; involucrate bract 1–3, 3 deeply lobed or lanceolate, acuminate; terminal umbels around 3 radiate, rays 0.2–2.5 cm long; involucellate bracteoles 7–10, lanceolate to lanceolate ovate, ca. 1–2 mm long. Umbellules 5–7 - flowered, staminate flowers 2–3 per umbellule, pedicels around 1 mm long, petals mainly white to purple blue, reduced stylopodium whitish or pale green. Fertile flowers usually 3 per umbellule, sessile or short-pedicellate; calyx teeth narrowly lanceolate, acute, ca. 1 mm long; styles ca. 1.5 mm long, recurved, stylopodium whitish or pale green. Mericarps obovate, subglobose or ellipsoid, 1.5–2.2 mm long, 2–2.4 mm wide, densely covered with uncinate bristles when mature, bristles yellow or purple-reddish. Vittae obscure.

Distribution.

Sanicula rugulosa is widely distributed in China ( Chongqing, Guizhou, Sichuan, Xizang and Yunnan) (Fig. 10 View Figure 10 ).

Habitat.

The species grows on mountain slopes under forest or along ravine streams near rocks or at forest margins at elevations of 1400–3400 m above sea level.

Phenology.

Flowering from later May to July, fruiting from June to September.

Etymology.

The epithet rugulosa is derived from the Latin term referring to the abaxial leaves sub-rugulose to rugulose.

Notes.

1) Sanicula astrantiifolia was described on the basis of three collections, namely E. E. Maire s. n., S. Ten 287 and O. Schoch 217. We have traced one specimen of the first collection at P (Fig. 1 B View Figure 1 ) and two specimens of the last collection at K and US (Fig. 1 C, D View Figure 1 ). All these specimens match the protologue well and are syntypes as Wolff (1930) did not designate a type for S. astrantiifolia ( McNeill 2014) . According to ICN Art. 9.17 ( Turland et al. 2018), Pimenov (2017) designated the P sheet as lectotype of this species; here we accept his treatment.

2) Sheh and Phillippe (2005) categorized Sanicula potaninii Bobrov as a synonym of S. astrantiifolia without providing sufficient rationale. Subsequently, Pimenov (2017) also classified S. potaninii as a synonym of S. serrata H. Wolff. However , our examination of living specimens and critical herbarium collections indicate that S. potaninii can be distinctly differentiated from S. astrantiifolia and S. serrata based on its habit and leaf morphology. Furthermore, S. potaninii shows a close affinity with S. serrata var. uncinata Shan & Constance , particularly in inflorescence and leaf characteristics. A thorough discussion regarding the taxonomic status of S. potaninii will be addressed in a separate analysis.
