Description from Flora of China

Coristospermum Bertoloni; Dystaenia Kitagawa; Ligusticopsis Leute; Paraligusticum V. N. Tikhomirov; Rupiphila Pimenov & Lavrova; Tilingia Regel & Tiling.

Herbs perennial. Root cylindrical or fusiform; rootstock thick or slightly inflated. Stem erect, striate, base usually clothed in fibrous remnant sheaths. Basal and lower leaves petiolate, sheathing; blade 1–3-pinnate or ternate-2–4-pinnate. Cauline leaves gradually reduced upward or absent. Inflorescence branching, rarely unbranched; umbels compound, terminal and lateral, or only terminal; bracts few, usually caducous or absent; rays often slightly incurved, convergent in fruit; bracteoles lanceolate or linear, entire or apex 2–3-lobed or 1–3-pinnate. Calyx teeth conspicuous, shorter than to subequal the stylopodium or obsolete. Petals white, purple, violet or pale pinkish, apex notched with incurved apical lobule. Stylopodium conic; styles spreading or erect in flower, reflexed after flowering. Fruit oblong or oblong-ovoid, dorsally compressed; ribs all prominent or lateral ribs narrowly winged; vittae (1–)2–5 in each furrow, 2–10 on commissure. Seed face plane, rarely slightly concave. Carpophore 2-cleft to base.

Ligusticum is a widespread, complex genus the taxonomy of which is in a state of flux. Relationships with nearby genera such as Cnidium, Hymenidium, Ligusticopsis, Pachypleurum, Paraligusticum, Rupiphila, Selinum, and Tilingia are still being clarified. As a general consensus has yet to be reached, and many species are very poorly known (often only from a type collection), a conservative, traditional classification has been adopted here, with the knowledge that Ligusticum in the broad sense is an artificial assemblage.

The following taxa have been described from Chinese material, but are imperfectly known as no specimens have been seen or the specimens are inadequate.

Ligusticum elegans H. Wolff (Acta Horti Gothob. 2: 312. 1926), described from Hebei (“Hsiao-wu-tai-shan [Xiaowutai Shan], Yang-kia-p’ing, Hsi-lin,” ca. 2200 m, K. A. H. Smith 1167, holotype, GB).

About 60 species: Asia, Europe, North America; 40 species (35 endemic) in China.
