Higher Taxonomy
Family: PlantaginaceaeView DescriptionDichotomous Key
Common Name: PLANTAIN FAMILY
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, Diplacus, Erythranthe, Limosella, Lindernia, Mimetanthe, Mimulus, Myoporum, Scrophularia, Verbascum). California Maurandya moved to Holmgrenanthe and Maurandella. Mohavea moved to Antirrhinum. Limnophila ×ludoviciana Thieret an occasional agricultural weed in rice fields. Hebe ×franciscana (Eastw.) Souster, Hebe speciosa (R. Cunn.) Andersen only cultivated.

Common Name: SPEEDWELL, BROOKLIME
Habit: Annual, perennial herb. Stem: erect or prostrate. Leaf: cauline, opposite, sessile to short-petioled. Inflorescence: raceme, terminal or axillary, or flowers 1 in axils; bracts small, alternate. Flower: sepals generally 4(5), +- free, generally unequal; corolla +- radial, +- rotate, generally 4-lobed, tube << lobes, upper lobe wide (perhaps formed by fusion of upper pair), blue or violet to white; stamens 2, exserted; stigma unlobed. Fruit: flattened perpendicular to septum, generally obcordate, loculicidal and septicidal.
Etymology: (Named for Saint Veronica) Note: Veronica beccabunga L., Veronica chamaedrys L. not in California; Veronica filiformis Sm., Veronica hederifolia L. occasionally as lawn weeds. Veronica biloba L., native to eastern Europe, Asia, a waif in southern Sierra Nevada Foothills, Modoc Plateau, differs from Veronica persica in ways including shorter styles (< 1 mm).

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
