A genus of four species in western North America (mainly in California) and northwest Mexico; they are herbaceous perennials but two become woody at the base and are usually classified as shrubs. Leaves more or less sessile, the lower ones opposite, the upper alternate. Flowers similar in most characters to those of the allied Fuchsia. Ovary globose, enclosed in the base of the floral tube (receptacle), which narrows above the ovary and then expands funnelwise. Sepals and petals four, spreading. Stamens eight. Fruit a capsule, resembling that of Epilobium. Seeds numerous, with a tuft of hairs at one end. The generic name commemorates Dr M. Zauschner, Professor of Natural History in the University of Prague (d. 1799).
The most recent study of the genus is: Clausen, Keck and Hiesey, ‘The Genus Zauschneria’, Carnegie Inst. Washington Publication 520, pp. 213-59 (1940), a work based on experimental cultivation and cytological study (botanical treatment and key by D. D. Keck.)
