Description from Flora of China

Sinodielsia delavayi (Franchet) Pimenov & Kljuykov.

Plants 20–50 cm. Stems several, erect, grayish-purple, distally fluted, puberulent; caudex stout, densely clothed with fibrous remnant sheaths. Basal leaves numerous; leaf blade ovate-oblong, 2-pinnate, pinnae 3–4 pairs; basal pinnae shortly petiolulate, others sessile; ultimate segments ovate to linear, 6–10 × 3–6 mm, 1–3-toothed, apex mucronate, pubescent abaxially on rachises and veins. Cauline leaves reduced upwards; petioles wholly sheathing. Umbels terminal, 6–10 cm across; peduncles densely hispid; bracts 3–4, linear, lanceolate or pinnate; rays 6–15(–24), subequal, 2–5 cm, hirsute; bracteoles 4–7, longer than flowers, pinnate; ultimate segments linear-lanceolate, hirsute. Calyx teeth absent. Petals white, obovate. Styles short. Fruit ellipsoid, ca. 4 × 2.5 mm; lateral ribs narrowly winged, wings slightly thickened; vittae (1–)2–3 in each furrow, 4–6 on commissure. Fl. Jul–Aug, fr. Aug–Sep.

This poorly known species is recorded only from a few collections. Its taxonomic placement is not fully resolved, and some authors consider it to be synonymous with Sinodielsia yunnanensis (Meeboldia yunnanensis in the present account).

Mountain slopes, grasslands, rock crevices; 2600–3400 m. NW Yunnan (Eryuan, Lijiang).
