Taraxacum hystrix is an intersectional intermediate. It is in many respects similar to T. consimile and seems close to T. sect. Suavia, T. sect. Variegata and T. sect. Leucantha (Kirschner & al. 2020: 113, 119).A


"Plants small, usually (5–) 7–10 9 (–12) cm tall. Petiole usually light green, narrow, unwinged to very narrowly winged, arachnoid but later often glabrescent, plant base with a few hairs, without tunic. Leaves ± mid-green, with light green, sometimes pinkish-bronze mid-vein, ± linear in outline, (4–) 5–7 (–10) × (0.4–) 0.6–1.5 (–1.9) cm, pinnatisect, with (3) 4–5 (6) pairs of linear to linear-triangular, patent to more often recurved lateral segments usually 4–8 × 1–2 mm, often dilated at base (or only on the distal margin at segment’s base), entire or rarely with a single tooth at or near the base of the distal margin; interlobes distinct, narrow, usually entire; terminal segment usually linear to linear-triangular, entire, ± acute, with short, ± linear basal lobules. Scapes brownish green, usually suffused purplish, arachnoid, ± overtopping leaves. Capitulum yellow, usually 1.5–2.5 cm wide. Involucre with contrasting colours, generally dark green, not pruinose, usually 7–9 mm wide and rounded at base. Outer phyllaries (9) 11–14 (16), ± imbricate, broadly ovate to ovate, the innermost ones (or sometimes all) lanceolate, usually from 6–7 × 3.0–3.7 mm to 8–9 × (1.0–) 2.0–2.5 mm, ± appressed, with a whitish membranous border 0.5–1.2 mm wide, margins not ciliate, middle part dark green, apex corniculate; inner phyllaries usually 10–12 mm, later during achene ripening reaching 16–17 mm, callose to corniculate. Outer ligules cucullate to canaliculate, striped grey-purple outside, inner ligules subtubular to cucullate, their teeth usually dirty pinkish or dirty yellow. Stigmas usually only imperfectly exserted, greyish green, with dark pubescence outside. Anthers polliniferous, pollen grains irregular in size. Achenes light grey stramineousbrown to ± light grey, (3.8–) 4.2–4.5 (–4.9) × 0.9–1.0 mm, body with remote long (to 0.3–0.4 mm), thin, stright, very acute, erect-patent spinules in the upper 1/2–3/4, mostly on ridges, sometimes descending almost to the base of the achene, body gradually narrowing into a ± cylindrical, thick (ca. 0.4–0.5 mm) cone (0.7–) 0.8–1.0 mm long, very abruptly narrowed into beak (beak therefore ± fragile) 4–4.5 mm long, 0.15–0.2 mm thick; pappus yellowish, 5–5.5 mm long. Agamosperm."
