Distribution
Deinandra minthornii is endemic from the Santa Susana Mountains, through the Simi Hills, to the Santa Monica Mountains of the southwestern Transverse Ranges, in Los Angeles and Ventura Counties, Southern California.[1][5][6][7]
This plant grows in the coastal sage scrub and chaparral habitats of the coastal sage and chaparral, and the chaparral habitat of the adjacent inland the montane chaparral and woodlands. It can be found on rocky outcroppings and in sandstone crevices, from 300–500 metres (980–1,640 ft) in elevation.[1][6] There are about 20 occurrences of the plant, but several have not been observed recently.[5]

The phyllaries lining the flower heads are coated in glands. The head contains four to eight yellow ray florets and several yellow disc florets.[6][8]
