狭锥花佩菊 xia zhui hua pei ju

Basionym: Prenanthes faberi Hemsley, J. Linn. Soc., Bot. 23: 486. 1888 ["Faberii"]; Lactuca hemsleyi Franchet, nom. illeg. superfl.; P. vitifolia Diels.

Herbs 1.2-2.5 m tall, perennial. Rhizomes horizontal, 1-2 cm in diam. Stem solitary, erect, ± glabrous, leafy, apically with or without branches as leafy as main stem. Stem leaves with petiole 2-6 cm; leaf blade triangular-ovate to pentagonal, 8-15 × 5-12 cm, glabrous or very sparsely with stiff hairs, base hastate to cordate, margin shallowly sinuately mucronately dentate and mucronulately denticulate, apex acute to acuminate; lower stem leaves rarely with a single pair of small, elliptic, entire, and subopposite to opposite lateral lobes. Synflorescences contracted paniculiform, with some to many capitula; branches short, wiry, often pilose. Capitula rather clustered, each with ca. 5 florets; peduncle 0-2 mm. Involucre ca. 10 × 3 mm. Phyllaries green, ± shortly white ciliate; outer phyllaries broadly ovate-triangular, longest 2.5-3(-5) mm, apex acute; inner phyllaries 5, apex obtuse. Florets pale purple. Achene brown, 3.5-4 mm. Pappus 6-8 mm. Fl. and fr. Jun-Aug.

● Mountain slopes, forest margins; 1800-3000 m. Chongqing, Guizhou, Sichuan, Yunnan.

Molecular phylogenetic analyses by N. Kilian et al. (in prep.) fully confirm the morphological affinity to Faberia of F. faberi, previously classified under Prenanthes (e.g., FRPS 80(1): 189. 1997).

The syntypes of Prenanthes vitifolia, collected by Rosthorn in Chongqing in 1891 and conserved at O with the annotation in Diels’s hand "Prenanthes vitifolia Diels" on the printed label of O, are evidence that P. vitifolia is conspecific with Faberia faberi. The sheet at O with the collection number "470" on an original handwritten label is designated here as the lectotype of the name Prenanthes vitifolia Diels.
