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: KeckiellaView DescriptionDichotomous Key

Habit: Subshrub or shrub. Stem: wand-like to much-branched. Leaf: drought-deciduous, +- opposite or in 3s, distal occasionally alternate; sessile to short-petioled. Inflorescence: panicle or spike-like; bracts reduced. Flower: calyx lobes 5, +- equal; corolla +- white, +- yellow, or red, short-glandular outside, upper lip +- hooded, 2-lobed, lobes rounded, external in bud, lower lip rounded, lobes often reflexed; stamens 4, filaments attached at 1 level, densely nonglandular-hairy at base, anthers small, glabrous, anther sacs generally spreading flat at dehiscence; staminode well developed, glabrous to densely bearded; nectary a disk; stigma unlobed. Fruit: septicidal and sometimes also loculicidal at tip, ovoid. Seed: many, irregularly angled.
Species In Genus: 7 species: especially California, western Nevada, western Arizona, Baja California. Etymology: (David D. Keck, California botanist, 1903--1995; Keckia used earlier, for genus of fossil algae) Note: Red-flowered species are hummingbird-pollinated.
