|discussion=<p>Variety membranaceum is a basically Mexican taxon that barely enters the flora area (southwesternmost Kern, western Imperial, Los Angeles, western Riverside, southeastern San Bernardino, San Diego, and southern Ventura counties). The ring-like petiole bases that surround the node are distinctive, being seen otherwise only in some of the perennial species of <i>Chorizanthe</i> in Chile. Ringed-stem bastard-sage is occasionally planted as an ornamental; it is particularly attractive to honey bees. The variety is related to both <i></i></i>var.<i><i> dentatum</i> (S. Stokes) Reveal and var. taxifolium (Greene) Parish of Baja California, Mexico.</p>
