Annual, perennial herb, shrub, vine. Leaf: simple or compound, cauline (or most basal), alternate or opposite; stipules 0. Inflorescence: cymes, heads, clusters, or flower 1; bracts in involucres or not. Flower: sepals generally 5, fused at base, translucent membrane generally connecting lobes, torn by fruit; corolla generally 5-lobed, radial or bilateral, salverform to bell-shaped, throat often well defined; stamens generally 5, epipetalous, attached at >= 1 level, filaments of >= 1 length, pollen white, yellow, blue, or red; ovary superior, chambers generally 3, style 1, stigmas generally 3. Fruit: capsule. Seed: 1–many, when wetted swelling or not, gelatinous or not.
26 genera, 314 species: America, northern Europe, northern Asia; some cultivated (Cantua, Cobaea (cup-and-saucer vine), Collomia, Gilia, Ipomopsis, Linanthus, Phlox). [Porter & Johnson 2000 Aliso 19:55–91] Leptodactylon moved to Linanthus. —Scientific Editors: Robert Patterson, Thomas J. Rosatti.
Key to Polemoniaceae
Glabrous to woolly, glandular or not. Stem: generally erect. Leaf: cauline, alternate, generally pinnate-lobed or simple; lobes generally linear or lanceolate. Inflorescence: head-like, bracted, generally densely woolly; bracts leaf-like; flowers sessile. Flower: calyx lobes unequal, generally woolly; corolla radial or bilateral, funnel-shaped to salverform; stamens equal or not, anthers generally sagittate, pollen white or blue; style included or exserted. Seed: 1–several per chamber.Key to Eriastrum
16 species: western North America. (Greek: woolly star) [Harrison 1972 Brigham Young Univ Sci Bull, Biol Ser 16:1–26] Apparently much undescribed variation; genus being revised. Key to species by David Gowen, Sarah De Groot.
Annual. Stem: to 35 cm. Leaf: 5–30 mm, thread-like, entire or 2-lobed near base, woolly. Flower: corolla 7–11 mm, ± salverform, radial, tube 3.5–6 mm, throat ± 1 mm, yellow to white, lobes 2–4 mm, pale blue to pink, generally with maroon spot at base (occasionally faint); stamens 1.5–2 mm, equal, ± exserted. Seed: 2 per chamber.
Pinyon/juniper woodland, sagebrush scrub, pine/oak woodland; 1000–2500 m. High Cascade Range (Shasta Valley), s Sierra Nevada Foothills, High Sierra Nevada, Transverse Ranges, East of Sierra Nevada (except White and Inyo Mountains), Modoc Plateau; Oregon, Nevada. Plants in Inner South Coast Ranges with 1 seed per chamber probably represent an undescribed taxon; study needed. May–Aug [Online Interchange]
