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
Stem: hairy or glandular. Leaf: alternate, simple, entire to generally pinnate-lobed, linear to ovate [fan-shaped]; basal short-petioled; cauline sessile. Inflorescence: heads or clusters, terminal, or flowers 1–3 in axils. Flower: calyx lobes connected by narrow membrane forming a pitcher-like projection at sinus, enlarging, not rupturing in fruit; corolla salverform to funnel-shaped. Fruit: ovate to elliptic, explosively dehiscent, valves reflexed on dehiscence. Seed: 1(2–3) per chamber, oblong, generally gelatinous when wet, brown.Key to Collomia
15 species: North America, southern South America. (Greek: glue, from wet seed surface) Annual species self-pollinated; perennial herb species generally cross-pollinated.

Annual. Stem: erect, simple or in robust plants branched above; internodes at mid-plant reflexed-short-white-nonglandular-hairy. Leaf: basal lanceolate, toothed or not; cauline lanceolate to linear, entire, lower glabrous to minutely hairy, upper in age also with glands. Inflorescence: head, terminal, occasionally on axillary stems. Flower: calyx 7–10 mm, lobes lanceolate; corolla 15–30 mm (< 5 mm in cleistogamous flowers), yellow to orange, fading white; filaments attached at > 1 level, some > 1 mm, at least 1 anther exserted; pollen generally blue. Seed: 1 per chamber.
