Key to families | Table of families and genera This text currently parallels The Jepson Manual: Vascular Plants of California, Second Edition that is now available at the University of California Press. Text appearing in blue on this page will not appear in the printed book; it will be displayed only on the Web. Specimen numbers are hyperlinked to records in the Consortium of California Herbaria data view where possible.

Annual to perennial herb, generally glabrous.
Stem: erect, simple or branched at base.
Leaf: generally opposite or whorled (or distal alternate), sessile, linear to ovate, generally wider on non- flower shoots, entire to dentate, pinnately veined.
Inflorescence: spike or raceme, terminal; bracts reduced, alternate.
Flower: sepals 5, free to near base, lobes ± equal; corolla 5-lobed, 2-lipped, lower lip >= upper, lower side of tube spurred at base, lower side of throat swollen, ± hairy, ± closing corolla below lips; stamens 4, in 2 pairs, included; stigma small, lobes 0 or 2, flat.
