Encelia californica
Encelia farinosa
Plants of Encelia farinosa with brown-purple disc corollas, found along the Colorado and Salt rivers, and common in Baja California, are var. phenicodonta. Plants with substrigose leaves, capitulescences branched toward bases rather than distally, and ray florets reduced in both size and number are most often hybrids and backcrosses between E. farinosa and E. frutescens. P. A. Munz (1959) indicated that I. L. Wiggins had reported var. radians Brandegee ex S. F. Blake as occurring in southeastern California; that variety is known only from Baja California.
