Systematics

Zhang & al. (2016) found Melanoseris henryi nested in their ITS tree in a clade together with the closely related species pair M. graciliflora and M. tenuis, which share the few-flowered capitula and reflexed ligules with M. henryi, and M. macrantha, M. likiangensis and M. atropurpurea, which are species with many-flowered capitula.B

Description

Herbs to 1–2 m tall, perennial. Stem solitary, erect, apically branched, glabrous, leafy. Lower stem leaves spatulate, to 15 × 5 cm, pinnatifid to pinnatipartite with 1–2 pairs of lateral lobes. Middle stem leaves spatulate, to 12 × 3 cm, pinnatifid to pinnatipartite, somewhat setose, base attenuate, margin sinuate-dentate, apex obtuse to acute; lateral lobes 1 or 2 pairs, semiorbicular to broadly ovate; terminal lobe ovate to lanceolate, as wide as lateral lobes. Upper stem leaves similar to middle stem leaves but smaller and less divided, apex acute to acuminate; uppermost stem leaves narrowly elliptic, undivided. Synflorescence paniculiform with some to many capitula. Capitula with 4 or 5 florets; peduncle wiry, sparsely setose. Involucre narrowly cylindric, 1.3–1.6 × ca. 0.3 cm. Phyllaries glabrous, apex obtuse; outer phyllaries lanceolate to linear-lanceolate, longest ca. 1/2 as long as inner ones; inner phyllaries (4 –)5, equal. Florets purplish, ligules conspicuously reflexed. Achene 0.8–1.1 cm; body reddish to purplish brown, narrowly ellipsoid, compressed, apex tapering into a paler 3–4 mm beak. Pappus ca. 7 mm.
