Systematics

In the circumscription by Ge & al. (2011) and Kirschner & al. (2020), Taraxacum sect. Qaisera includes more than 40 species and its distribution is centred in Middle Asia (from SE Kazakhstan to Tadjikistan) and extends to the E Tian Shan, Xinjiang and the W Himalaya. Most members are agamospermous hybridogenous species; Kirschner & al. (2020: 345) hypothesize that one of the parental taxa may belong to the predominantly sexual T. sect. Calanthodia.B,C

Description

Plants medium-sized. Leaves light green to deep green, arachnoid, not thickened; petiole usually purplish or pinkish, usually broadly to narrowly winged but in inner leaves sometimes unwinged; leaf blade usually pinnatisect; lateral lobes usually triangular, subrecurved. Outer phyllaries usually 13–19, ovate, broadly ovate, or sometimes ovate-lanceolate, usually appressed, loosely appressed erect, or ± erect-patent, venation distinct or not clearly visible, border narrow to broad, apex usually flat or sometimes corniculate. Ligules yellow; ligule tube pubescent with straight hairs. Achene grayish straw-colored brown, 3.6–5 × 0.9–1.2 mm; body often with prominent lateral ridges (narrowly winged), densely shortly spinulose above, abruptly to almost gradually narrowing into a conic to subcylindric 0.4–0.8(–1.1) mm cone; beak usually 6–10 mm, thin.
