Corolla 4–5-lobed; tube short, rarely exceeding calyx. Calyx 4- or 5-partite; where present, fifth posterior lobe usually smaller. Pedicels ebracteolate. Flowers in terminal or axillary racemes or rarely solitary-axillary, bracteate. Stamens 2, perfect, exserted; inserted on corolla tube at sides of upper lobe; anther-thecae divergent or parallel, obtuse. Seeds few to many. Annual or perennial herbs, erect, prostrate or decumbent, glabrous or pubescent. Leaves opposite or occasionally verticillate or scattered, entire or variously dentate or crenate. Style apically subcapitate. Capsule compressed or turgid, bisulcate, loculicidal. Calyx 4- or 5-partite; where present, fifth posterior lobe usually smaller. Pedicels ebracteolate. Flowers in terminal or axillary racemes or rarely solitary-axillary, bracteate. Stamens 2, perfect, exserted; inserted on corolla tube at sides of upper lobe; anther-thecae divergent or parallel, obtuse. Seeds few to many. Annual or perennial herbs, erect, prostrate or decumbent, glabrous or pubescent. Leaves opposite or occasionally verticillate or scattered, entire or variously dentate or crenate. Style apically subcapitate. Capsule compressed or turgid, bisulcate, loculicidal.

Cal deeply 4-parted in our spp. (5-parted in some no. 12 [Veronica officinalis L.]), the lobes equal or the upper shorter; cor-tube much shorter than the lobes (except in no. 1 [Veronica longifolia L.]), the limb rotate, obscurely 2-lipped, 4-lobed by fusion of the upper 2; stamens 2 (the upper pair), inserted at the orifice of the cor; pollen-sacs parallel; style exsert; stigma 1; fr short, often flattened, loculicidal and sometimes also septicidal, subtended by the sep and tipped by the persistent style; herbs with opposite (rarely whorled) foliage-lvs, the bracteal lvs mostly alternate or scattered; fls small, white to blue or purple. 300, N. Temp., especially Old World.

Veronica is a genus of over 200 species mainly of temperate parts of the Old World, but a few species are native to the Americas.

Annual or perennial herbs, often prostrate or ascending; stems terete or angled, often branching at the base. Leaves opposite, at least below, mostly pubescent with simple, multicellular hairs or glandular hairs; petioles distinct or not. Inflo- rescences either in alternate-bracted elongate racemes or solitary flowers in the axils of terminal unmodified leaves. Flowers mostly small, the calyx divided nearly to the base, the 4(5) lobes mostly narrow, entire, often exceeding the flowers; corolla rotate or campanulate, blue or white, rarely yellow, somewhat lobed; stamens 2, the anthers exserted; style straight, the stigma capitate. Capsule flat- tened perpendicular to the septum, the carpels discoid or lenticular, marginally connate, loculicidal or sometimes septicidal; seeds numerous, variously orna- mented.
