Species 21 (16 in the flora).
Deinandra is treated here as distinct from Hemizonia; Deinandra is more closely related to Calycadenia, Centromadia, Holocarpha, and Osmadenia than to Hemizonia in the strict sense (S. Carlquist et al. 2003). As circumscribed here (following B. G. Baldwin 1999b), Deinandra comprises all taxa included in Hemizonia sect. Madiomeris by B. D. Tanowitz (1982) plus the shrubs and subshrubs constituting the informal “Fruticosae” or “Zonamra” (J. Clausen 1951; D. D. Keck 1959b). All are self-incompatible except D. arida and D. mohavensis. Five species (D. frutescens, D. greeneana, D. martirensis, D. palmeri, D. streetsii), none annuals, are known only from Baja California, Mexico. Most species north of Mexico are cross-incompatible or ± intersterile (J. Clausen 1951).
