Discussion

Of conservation concern.

Deinandra paniculata occurs in dry foothills, mesas, and valleys of the southern Peninsular Ranges and South Coast and in the central South Coast Ranges. Plants from the South Coast Ranges, previously treated as D. increscens subsp. foliosa, may warrant recognition as a distinct taxon.
