Sinodielsia cuneata (H. Wolff) Pimenov & Kljuykov.

Plants 30–40 cm. Root stout, long-conic. Stem slender, ribbed, a little branched above. Basal petioles 6–15 cm, flattened, sheaths short, narrow; blade broadly rhombic-ovate in outline, ternate/pinnate; pinnae 3-parted; ultimate segments oblong, 8–15 × 2–5 mm, apex 2–5-lobed, base cuneate, slightly decurrent. Umbels terminal, ca. 2–4.5 cm across; peduncles 5–10 cm; bracts often absent, rarely 1, ovate, 1–1.2 cm; rays 5–6, slender, 2–4 cm, unequal; bracteoles 4–6, linear, shorter than pedicels; umbellules 8–15-flowered. Calyx teeth triangular-ovate, to 0.5 mm. Petals white, ca. 1.3 × 1 mm, midvein conspicuous, apex obtuse. Young fruit broadly ovoid, ca. 2 × 2 mm, mature fruit unknown. Fl. and fr. Oct–Dec.

Open grasslands; 3300–3400 m. Sichuan, Yunnan.

This species is unusual within the genus by the lack of conspicuous bracts and bracteoles. However, it is a poorly known taxon, recorded only from a few collections. The generic assignment is therefore tentative pending further study, as the species may be better placed in Tongoloa or, if recognized, Sinodielsia.
