Sinodielsia delavayi (Franch.) M. G. Pimenov & E. V. Kljuykov

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).

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.
