Annual herbs, aromatic; leaves narrow, linear to spathulate, entire or toothed; inflorescence of (1-)3-6-flowered sessile, rarely shortly pedunculate cymes in axils of bracts, congested into dense, terminal, spike- or head-like thyrse; bracts usually narrow (lower leaf-like); bracteoles elongate, linear, curved, often conspicuously ciliate; calyx 2-lipped, 5-lobed (3/2), lobes narrowly triangular, posterior usually shorter, tube 15-nerved, narrowly infundibuliform, throat glabrous; corolla lavender to purple, rarely white, or yellowish, 2-lipped, 4-lobed (1/3), lobes short, posterior lip flat, entire, tube elongate, narrowly infundibuliform to campanulate; stamens 4, posterior pair shorter and, in some species, staminodal, anterior pair ascending under posterior lip of corolla, included to slightly exserted, thecae ± parallel, distinct, often slightly unequal, connective apparent; style usually hairy above; stigma-lobes equal to unequal; disc symmetrical; nutlets oblong-obovate with rounded, usually hairy apex. 2n = 38. Seven species, mostly in U.S.A., California, extending to Oregon and Mexico (Baja California). Open, usually seasonally flooded, areas. Howell (1931) recognized two subgenera: subg.
