The genus Veronica currently includes about 450 species (Albach et al. 2004b, Mabberley 2008), which are found mostly in temperate northern hemisphere areas and Australasia. Veronica plants are herbs, subshrubs, shrubs or small trees with opposite, usually decussate, leaves and opposite or alternate floral bracts. The four, rarely five, calyx lobes are usually very shortly connate at the base, or occasionally the anterior; or rarely the posterior pair are fused over most of their length. The corolla has a short to long tube and a spreading limb of four unequal (rarely five sub-equal) lobes. There are just two stamens, attached to the corolla tube. The pistil has a single style and stigma with a two-chambered ovary (in V. benthamii, often three-chambered) and axile placentation. The fruit is a capsule with two locules (often three in V. benthamii), either flattened orthogonal to a narrow septum (angustiseptate), and then usually notched, or flattened parallel to a broad septum (latiseptate), and then usually acute. The seeds are varied in size, shape, and ornamentation, but small, elliptic, smooth, and flattened in most species.
