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.

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.

Species: Leptosiphon chrysanthusView Description 

Habit: Annual. Stem: thread-like, glabrous or hairy, glandular or not. Leaf: lobes 3--6 mm, linear. Inflorescence: flower 1; peduncle 5--15 mm, thread-like. Flower: calyx 4--6 mm, membrane wider than lobes; corolla funnel-shaped, tube 3--5 mm, with hairy ring inside and out, lobes 5--7 mm, oblanceolate; filaments glabrous, attached above hairy ring, in throat; stigmas 3--4 mm, exserted.
Note: Name changed because Leptosiphon aureus used earlier (and now again) for taxon called Leptosiphon acicularis in TJM2. Following subspecies overlap in geography but do not occur together.
