Collinsia bartsiifolia var. bartsiifolia

Higher Taxonomy
Family: PlantaginaceaeView DescriptionDichotomous Key

Habit: Annual to shrub, some aquatic. Leaf: basal or cauline, alternate or opposite (whorled), simple, entire to dentate or lobed, venation generally pinnate; stipules 0. Inflorescence: raceme, spike, or flowers axillary in 1--few-flowered clusters; flowers few to many, each subtended by 1 bract. Flower: unisexual or bisexual, radial or bilateral; sepals 4--5, generally fused at base; corolla 4--5-lobed, scarious or not, persistent or not, generally 2-lipped, upper lip generally 2-lobed, lower generally 3-lobed, spur present or not, tube sac-like at base or not; stamens 2 or 4, alternate corolla lobes, epipetalous, staminode 0 or 1--2, anthers opening by 2 slits; ovary superior, [1]2--4-chambered, style 1, stigma lobes 0 or 2. Fruit: generally a capsule, septicidal, loculicidal, circumscissile, or dehiscing by terminal slits or pores.
Genera In Family: 110 genera, +- 2000 species: worldwide, especially temperate. Note: Veronicaceae sensu Olmstead et al. Recently treated to include Callitrichaceae, Hippuridaceae, and most non-parasitic California genera of Scrophulariaceae (except Buddleja, Limosella, Mimulus, Myoporum, Scrophularia, Verbascum). California Maurandya moved to Holmgrenanthe and Maurandella. Limnophila ×ludoviciana Thieret an occasional agricultural weed in rice fields. Hebe ×franciscana (Eastw.) Souster, Hebe speciosa (R. Cunn.) Andersen only cultivated.

Genus: CollinsiaView DescriptionDichotomous Key

Habit: Annual, often glandular, sometimes brown-staining. Leaf: opposite; proximal petioled. Inflorescence: bracted, often interrupted; flowers 1--many in leaf axils. Flower: calyx lobes 5, generally glabrous on inner surface; corolla +- pea-like, uniformly pale, or generally with pale regions, especially throat and base of upper lip (+- uniformly dark in Collinsia greenei), generally glabrous outside, tube short, throat +- angled to tube, +- pouched on upper side, lips generally +- = throat, upper lobes 2, +- reflexed, lower lobes 3, lateral spreading, central lobe keeled, enclosing stamens and style; stamens 4, attached unequally near throat base, spur at base of upper filaments > 1 mm, vestigial, or 0; staminode gland-like; style > 2 mm, stigma minutely 2-lobed. Fruit: septicidal and loculicidal (valves 2-lobed). Seed: generally few, +- oblong, generally plump; inner surface +- concave.
Species In Genus: +- 20 species: North America, especially California. Etymology: (Zaccheus Collins, Philadelphia botanist, 1764--1831) Note: Late-season flowers generally atypically small.

Species: Collinsia bartsiifoliaView Description 

Leaf: generally 1--4 cm, +- thick, +- oblong, obtuse, crenate, rolled under, generally finely hairy. Inflorescence: interrupted, +- glandular or shaggy-hairy; whorls dense; pedicel < calyx. Flower: calyx lobe tips +- blunt; corolla drying veiny, throat longer than wide, hairy inside, lips +- equal or upper lip 1/2--2/3 lower lip, upper lobes +- oblong, +- toothed, backs often touching or parallel, lateral lobes obovate, notched or +- entire; upper filaments hairy, basal spur 0--0.5 mm. Seed: many, +- plump, 1--1.5 mm. Chromosomes: n=7.
Note: Corolla size in populations varies with climate across years. Varieties not distinct in SCoRO and northern WTR; study needed.

Collinsia bartsiifolia Benth. var. bartsiifolia
Habit: Plant (10)20--35 cm. Flower: corolla 15--20 mm, generally white to pale lavender, lips +- equal, lateral lobes notched.
Ecology: Open, sandy places; Elevation: generally < 600 m. Bioregional Distribution: NCoRO/KR (Humboldt Co.), NCoRI, CaRF, c&s SNF, Teh, GV, s SnFrB (Santa Cruz Co.), SCoRO, n WTR. Flowering Time: Mar--Jun Note: Plants called Collinsia bartsiifolia var. hirsuta (Kellogg) Pennell with upper corolla lip intermediate in size to short lip of Collinsia corymbosa, historically known from northern CCo (San Francisco, Marin cos.), apparently extirpated.
