Higher Taxonomy
Family: PolemoniaceaeView DescriptionDichotomous Key

Habit: 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.
Genera In Family: 26 genera, 314 species: America, northern Europe, northern Asia; some cultivated (Cantua, Cobaea (cup-and-saucer vine), Collomia, Gilia, Ipomopsis, Linanthus, Phlox). Note: Leptodactylon moved to Linanthus.

Habit: Annual, perennial herb, subshrub. Stem: generally erect, generally branched from base. Leaf: cauline, alternate or opposite, entire or lobes 3--9, pinnate or palmate, linear to narrow-lanceolate or spoon-shaped. Inflorescence: open or dense clusters or cyme or flower 1; bracts leaf-like; flowers sessile or not. Flower: corolla funnel-shaped, salverform, or bell-shaped; stamens attached at 1 level, included or exserted, pollen yellow. Fruit: capsule, valves 3(4). Seed: generally many, when wet gelatinous to not.
Species In Genus: 25 species: western North America. Etymology: (Greek: flax flower) Note: Other taxa in TJM (1993) moved to Leptosiphon. Linanthus bernardinus described since TJM2 (Fraga & Bell 2012 Aliso 30: 97--102).

Linanthus pungens (Torr.) J.M. Porter & L.A. Johnson
Habit: Perennial herb, subshrub, generally hairy, glandular or not. Stem: 1--3 dm. Leaf: alternate, lobes 3--7, palmate, sharp-tipped, middle generally longest. Flower: generally open evening; calyx lobes generally unequal, membrane much wider than lobes; corolla funnel-shaped, tube and throat 7--15 mm, white or light pink, lobes 7--10 mm, obovate, white or pink with darker shading on abaxial margins; stamens attached at throat. Fruit: < calyx, narrowly ovoid. Seed: 15--30, not gelatinous when wet. Chromosomes: 2n=18.
Ecology: Open, rocky areas in montane, subalpine forest, alpine fell-fields; Elevation: 1700--4000 m. Bioregional Distribution: CA; Distribution Outside California: to British Columbia, Rocky Mountains. Flowering Time: May--Aug Note: Some proposed subspecies sort well elsewhere, but not in California; further study needed.
