Is the largest genus in the flowering plant family Plantaginaceae, with about 500 species; it was formerly classified in the family Scrophulariaceae. Taxonomy for this genus is currently being reanalysed, with the genus Hebe and the related Australasian genera Derwentia, Detzneria, Chionohebe, Heliohebe, Leonohebe and Parahebe included by many botanists. Common names include speedwell, bird's eye, and gypsyweed.
The species are herbaceous annuals or perennials, and also shrubs or small trees if Hebe is included. Most of the species are from the temperate Northern Hemisphere, though with some species from the Southern Hemisphere; Hebe is mostly from New Zealand.
