翼柄蒲公英 yi bing pu gong ying
Herbs 4-6 cm tall. Petiole narrowly winged; leaf blade ± mid-green, oblanceolate, 2.5-4.5 × 0.5-0.9 cm, ± glabrous, not divided or margin shallowly pinnatilobed to remotely dentate; lateral lobes or teeth 1 or 2 pairs, triangular, 1-2 mm, patent to subrecurved, margin entire; interlobes broad or not developed in undivided leaves, margin entire; terminal lobe triangular, margin entire, apex subacute. Scapes suffused purplish, ± equaling leaves, arachnoid and densely white arachnoid below capitulum. Capitulum ca. 2 cm wide. Involucre 5-6 mm wide, base rounded. Outer phyllaries 11-15, surface evenly blackish dark gray, ± imbricate, ovate to broadly ovate, outermost ones (2.2-)3-4.5(-5.5) × (2.5-)3-4.2 mm and 1/2-3/5 as long as inner ones, appressed, margin glabrous, apex almost flat in first capitula but black corniculate in later ones; inner phyllaries blackish, 1-1.3 cm, ± flat or corniculate below apex. Ligules golden yellow; outer ligules flat, outside striped gray; floret tube glabrous. Stigmas blackish. Achene blackish brown, 3.7-4.3 × 1-1.1 mm; body sparsely and minutely spinulose or tuberculate above, ± gradually narrowing into a conic 0.5-0.6 mm cone; beak 4-5 mm. Pappus slightly yellowish white, ca. 5 mm. Fl. summer.● Wet alpine grasslands; ca. 3400 m. Xinjiang.
Taraxacum alatopetiolum is similar to T. atrans Schischkin but differs in having more numerous outer phyllaries.
