Subshrubs, 15–30 cm (in rock crevices, stems relatively many, erect to pendulous); sparsely to densely short-hairy, glandular. Leaves: petioles 2–15 mm; blades deltate-ovate to ovate-rhombic, 6–23 × 5–24 mm, margins usually entire or serrate to serrate-crenate, sometimes shallow-lobed. Heads in corymbiform arrays, 5–7 × 5.5–7 mm. Peduncles 5–25 mm. Involucres campanulate. Phyllaries 13–20, linear-lanceolate to narrow-ovate, 4–5.5 × 1–2 mm. Ray florets 6–10; corollas white, sometimes pink tinged, laminae broadly oblong to oblong-elliptic, 3–7 × 1.5–3 mm. Disc florets 30–40; corollas yellow, often purple tinged, tubes 0.8–1 mm, throats tubular to tubular-funnelform, 1.2–1.4 mm, lobes 0.3–0.4 mm. Cypselae linear-oblong to oblanceolate, 2–2.8 mm, margins prominently calloused, long-ciliate; pappi of 2(–3+) barbellulate bristles 1.5–2.5 mm plus crowns of hyaline, laciniate scales. 2n = 34.
Phenology: Flowering spring–fall.
Habitat: In rock crevices
Elevation: 1100–2500 m
Discussion
Perityle ciliata is found only in the mountains of central Arizona in Apache, Coconino, Gila, Mohave, and Yavapai counties. It appears to be most closely related to P. coronopifolia.
