Habit: Annual, perennial herb. Stem: decumbent to erect, 10--100 cm, glandular-hairy, hairy, or glabrous. Leaf: pinnate-compound, alternate; basal petiole base membranous or not, sheathing or not; cauline sessile above; leaflets entire to divided, glabrous to glandular-hairy. Inflorescence: cyme or head. Flower: calyx bell-shaped, membranous in age but not separated into membrane and lobes, glandular-hairy; corolla rotate to funnel- or bell-shaped, tube << throat, lobes white to blue or purple; stamens attached at 1 level, filaments hairy at base; ovary generally +- 1 mm, +- 1 mm wide. Fruit: ovoid to spheric. Seed: <= 10, generally 1--3 mm, elliptic to ovate, +- gelatinous when wet, brown to black. Etymology: (Greek: perhaps from Polemon, Athenian philosopher, or polemos, strife or war) Note: Perennial herb generally cross-pollinated, annual self-pollinated.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
