Perennials, 3–7 cm (forming dense clumps and mats). Stems 3–10+, bases relatively think. Leaf-blades linear-oblanceolate, 2–5 cm × 1–3 mm; cauline progressively reduced to linear bracts.

Florets 20–30; corollas pink, 6–8 mm. Cypselae 4–5 mm; pappi 2–3 mm.


Phenology: Flowering Jun–Jul.
Habitat: Exposed slopes, rocky ledges, limestone cliffs
Elevation: 1800–2200 m

Discussion

Pinaropappus parvus is easily recognized by the extremely dense clumping habit, relatively short stems, and relatively small heads. At flowering, the phyllaries are usually purple in the center with scarious margins and purple to dull brown tips.
