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
Annual, perennial herb. Stem: generally erect, generally branched from base. Leaf: cauline, opposite, entire or lobes 3–9, palmate, linear to narrowly lanceolate or spoon-shaped, generally not fused by membrane. Inflorescence: head, open clusters, few-flowered cyme, or flower 1; bracts ± leaf-like, generally palmate-lobed, lobes generally not connected by translucent membrane; flowers sessile or not. Flower: sepals generally equal; corolla funnel-shaped, salverform, or bell-shaped, with hairy ring inside tube or generally not (determined at 10×); stamens attached at 1 level, pollen yellow.Key to Leptosiphon
30 species: western North America, Chile. (Greek: narrow tube, for corollas of some species) [Battaglia & Patterson 2001 Madroño 48:62–78] Calyx lobe membrane generally expressed as length relative to calyx or lobe length, or as width relative to calyx lobe.
Annual, hairy. Stem: 2–21 cm. Leaf: lobes 3–13 mm, narrowly obovate to linear. Inflorescence: head, generally 1 flower open at a time in each inflorescence, late morning, closed by early evening. Flower: calyx 6–11 mm, ciliate, nonglandular, membrane obscure; corolla salverform, tube 12–32 mm, thread-like, ± red, throat yellow, lobes generally < 4 mm, obovate, rounded or truncate, pink, white, or pale yellow; stamens exserted; stigmas <= 1(3) mm.
