Stem erect, to 70 cm tall, ca. 3 mm in diam. at base, longitudinally angulate.

Achenes cylindric, ca. 5 × 0.6 mm, longitudinally ribbed, apex truncate. Pappus brown, 4-5 mm, as long as or shorter than tube of tubular corolla. Fl. Jul-early Aug.

● Wet grassy slopes along forest margins, alpine meadows along streams; 2700-3400 m. NE Yunnan (Dongchuan, Qiaojia).

The population size is very small at two known localities, so Ligularia qiaojiaensis should be categorized as "endangered" (Dong & Chen, Nordic J. Bot. 28: 683. 2010).

One of us (Illarionova) believes that Ligularia qiaojiaensis is an occasional hybrid of L. przewalskii and some species from the same section.
