PLANTAGINACEAE PLANTAIN FAMILY

Margriet Wetherwax, except as noted

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.
110 genera, ± 2000 species: worldwide, especially temperate. [Angiosperm Phylogeny Group 1998 Ann Missouri Bot Gard 85:531–553; Olmstead et al. 2001 Molec Phylogen Evol 16:96–112] 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. —Scientific Editors: Robert Patterson, Bruce G. Baldwin.
