Taproot straight or slightly oblique, fleshy, with lateral roots (Fig. 2D). Stems erect, branched from the base, with sparse white simple hairs; stem base ribbed, with 1 or 2 leaves similar to basal leaves. Basal leaves crowded at the caudex base; petiole 2-3 cm long; blade oblanceolate, 6-18 × 2-4 cm, both surfaces short pubescent with white hairs 0.1-0.3 mm long (pubescence more evident on veins), bipinnate to pinnatifid, apical lobe halberd-shaped, apex acute-acuminate, margin deeply lobed; lateral lobes 5-10 pairs, opposite or slightly skewed, irregularly halberd-shaped (lateral lobes tapering to the base, serrate, lowermost lobes narrowly triangular), often with 1-3 pairs of triangular or oblique-ovate lobes between lateral lobes. Synflorescence corymbiform; capitula 7-10. Involucre ampullate, 3-4 mm long, 3 mm in diameter. Phyllaries in 4 rows, greyish-green; outer phyllaries 5-7, ovoid-triangular, ca. 1 × 1 mm, apex acute; inner phyllaries 7-9, lanceolate, 2-4 × 0.5-1 mm, margin white-membranous, apex acute; florets 8-10, ligules 4-6 × 1-2 mm, teeth 0.2-0.4 mm long, tube 3-4 mm; anther tube ca. 2.5 mm long; style branches ca. 0.5 mm long. Outer achenes black, fusiform, 2 mm long, apex attenuate to shortly beaked and expanded again into the pappus disc; ribs 12-14; pappus white, bristles rough, 3 mm long; inner achenes similar to the outer ones, 2.5 mm long.</p> <p>Phenology.</p> <p>Flowering and fruiting April to October.</p> <p>Vernacular name.</p> <p>五峰黄鹌菜, wǔ fēng huánɡ ān cài in Chinese Pinyin.</p> <p>Etymology.</p> <p>The species epithet honours Prof. Hang Sun (b. 1963), a Chinese botanist who has conducted research on plant taxonomy, floristics, biogeography and evolutionary biology and inspired many people through his work. He has also given a lot of support to the plant research work in Hubei.</p> <p>Distribution and habitat.</p> <p>Youngia hangii is known only from the type locality, Renheping in Wufeng Xian, Hubei, China; 500-1000 individuals are known along the edge of some small caves at the base of the karst hillside (Fig. 2A, B, C); at altitudes of 500-800 m.</p> <p>Morphological assessment.</p> <p>Morphological characteristics suggest that Y. hangii is related to Y. rubida and Y. heterophylla owning 10-25 florets and resembles Y. rosthornii with bipinnately deeply partite leaves. The achenes of Y. hangii and Y. rubida are attenuated into a short beak, which is widened into the pappus disc. Several unique features including the shape, lobes and size of the leaves, the leaves with white simple hairs (Fig. 2E, F, G; Fig. 3F, G), phyllaries, number of florets and achenes differentiate Y. hangii from Y. rubida and Y. heterophylla (Table 1).</p> <p>Phylogenetic analysis.</p> <p>The Bayesian tree showing PP support, ML bootstrap (LP) and MP bootstrap (BP) values for each clade are presented in Fig. 1. The species in clade Ι form a monophyletic group with PP = 0.97, but LP are with weak support and BP are in conflict with PP and they were instead with “-”, respectively in Fig. 1. Youngia hangii is nested within Clade I as sister to Y. rubida with strong support (PP = 1, LP = 83, BP = 88).</p> </div>	http://treatment.plazi.org/id/51E31F18D526526C84F8B676EDD58ACD	Public Domain	No known copyright restrictions apply.
