Annual, perennial herb
Stems decumbent to erect, 1–10, 1–10 dm, glandular, hairy
Leaves pinnately compound, alternate; basal petioled; cauline sessile upward; leaflets entire to divided, glabrous to glandular
Inflorescence open to head-like
Flower: calyx bell-shaped, membranous in age but not separated into membrane and ribs, glandular; corolla rotate to funnel-shaped, white to blue or purple; stamens attached at same level, filaments hairy at base
Fruit ovoid to spheric
Seeds 3–10 per chamber, generally 1–3 mm, elliptic to ovate in outline, slightly gelatinous when wet, brown to black
Species in genus: ± 20 species: Am, Eurasia
Etymology: (Greek: perhaps from Polemon, Athenian philosopher, or polemos, strife or war)

P. chartaceum H. Mason

MASON'S SKY PILOT

Perennial, hairy
Stems erect, 3–8, < 3 dm
Leaves basal, narrowly oblong in outline; petioles sheathing, membranous at base, brownish; leaflets > 13, < 5 mm, deeply 3–5-lobed; lobes generally elliptic, glandular, appearing as whorled leaflets
Inflorescence head-like; pedicels < 5 mm
Flower: calyx 6–8 mm, lobes = tube, rounded; corolla 10–14 mm, funnel-shaped, tube > lobes, white, throat blue or yellow, lobes blue; stamens and style exserted
Ecology: UNCOMMON. Rocky slopes, talus,
Elevation: 2600–4200 m.
Bioregional distribution: Klamath Ranges, East of Sierra Nevada (Sweetwater Mtns), White and Inyo Mountains
Flowering time: Jul–Aug
Probably related to both P. eximium (c&s SNH) and P. elegans Greene (WA, B.C.); warrants further study, especially because of interrupted range
