Systematics

Melanoseris cyanea is a widespread and polymorphic species, or, more likely, species complex. It has been argued by Wang & al. (2013) that the wider concept of the species, compared to Shih (1997), applied by Shih & Kilian (in Shih & al. 2011) is still too narrow: (1) The delimitation towards M. beesiana ( = Chaetoseris lyriformis C. Shih, providing the type of the name of Chaetoseris) as well as towards M. sichuanensis breaks, when considering besides leaf shape features also relevant capitula and flower features. (2) The status of the yellow-flowered plants and populations treated by Shih & Kilian (2011) under Melanoseris yunnanensis ( = Chaetoseris lutea = C. teniana) is still not fully clear, but their very close relationship to M. cyanea is evidenced by molecular analysis (Wang & al. 2013). (3) Status and assignment of M. pectiniformis are still in question but this taxon is probably also conspecific with M. cyanea according to Wang & al. (2013).

Description

Herbs 0.8–1.8 m tall, perennial. Root slenderly turniplike. Stem solitary, erect, branched apically, ± glabrous to densely covered with purplish to brownish glandular hairs. Lower and middle stem leaves with petiole to 12 cm, narrowly winged, basally semiamplexicaul, not or rarely very faintly sagittately clasping; leaf blade ovate to triangular, 5–11(–17) × 3.5–8.5(–13) cm, undivided or with 1 pair (or 2–3 pairs) of ± elliptic lateral lobes, margin coarsely dentate, base of blade or terminal lobe cuneate, truncate, cordate, or hastate, apex acute. Upper stem leaves shortly petiolate to sessile; leaf blade similar to middle stem leaves but smaller, narrowly elliptic, undivided to shallowly pinnatifid. Synflorescence narrowly racemiform or paniculiform, often with rather long virgate branches, with few or several to numerous capitula. Capitula with 15–30 florets. Involucre cylindric, 1.2–1.5 × 0.5–0.8 cm. Phyllaries with midvein white or purplish hispid except in innermost ones, apex obtuse to acute; outer phyllaries triangular-ovate to lanceolate. Florets blue to purplish (sometimes yellow?). Achene (5–)6–8 mm; body pale to dark brown, ellipsoid, compressed, lateral ribs broadened, apex attenuate into a pale (1&ndash)2–3 mm slender beak. Pappus double, outer hairs 0.1–0.3 mm, bristles 7&nadsh;8 mm. Fl. and fr. Aug–Nov. 2n = 16*.
