Faberia pinnatifida Ying Liu, Yousheng Chen & Boufford , sp. nov. TYPE: CHINA. Sichuan: Yanyuan County, E of Wodi-xiang ; around summit of Huolu Shan Peak, scree slopes, meadows, and adjacent primary Picea forest over limestone; 27°54 0 110N, 101° 37 0 50E; 4300–4320 m, 13 Aug 2010, D.

Herbs, perennial, 46–75 cm tall, with short rhizomes. Stems erect, glabrous, branched apically. Rosette leaves narrowly elliptic to oblanceolate; petiole 3–8 cm long, blade 6–16 3 2.5–6.7 cm, lyrately pinnatifid to pinnatipartite, base cuneate and narrowly decurrent along petiole, apex acute to acuminate, abaxially pale glaucous, adaxially green and glabrous; lateral lobes 8–14, triangular to broadly ovate, gradually smaller toward leaf base; terminal lobe triangular to lanceolate. Stem leaves usually 1 or 2, only one leaf similar to rosette leaves; upper leaf often linear and bract-like. Synflorescence laxly branched, corymbiform, with 2–7 capitula. Capitula nodding, with ca. 30 florets. Involucre ca. 15 3 6 mm. Phyllaries abaxially dark green, glabrous, apex obtuse or acute, margin and apex shortly whitish fimbriate; outer phyllaries ovate to triangular-ovate, largest 5–7 3 3–4 mm; inner phyllaries ca. 14, 13–15 3 3–4 mm. Florets purplish blue. Achenes brown, narrowly ellipsoid, 4–5 mm long, apex truncate. Pappus brownish, ca. 6 mm long. Flowering August–September, fruiting September–October. Figure 6 .

Distribution and Ecology —Known from northern Yanyuan Xian and southern Muli Xian, Sichuan, China, on scree slopes, in meadows, thickets, and primary Picea forests over limestone.

Etymology —The epithet is based on the pinnately lobed to partite leaves.

Conservation Concerns — Faberia pinnatifida is known only from a small area around northern Yanyuan and southern Muli xian. Of the two populations known, the one at the Muli-Yanyuan Pass included no more than 50 clumps. The extent of the population on Huolu Shan was not determined.

Additional Specimen Examined — China. — SICHUAN: Muli Xian. Xiamaidixiang, Muli-Yanyuan Pass, 27° 44 0 4.130N, 101° 14 0 5.710E, 3000 m, 25 Aug 2015, FLPH Sichuan Expedition 151148 (PE).
