Calif., Mexico (Baja California).
Discussion
Variety glabriuscula is known mainly in and west of the Peninsular Ranges and adjacent desert edges, inland from the coast; it also extends to Santa Rosa Island. Northward it intergrades with vars. megacephala and lanosa; near the coast it intergrades with var. orcuttiana. Forms sometimes recognized as var. tenuifolia are distinctive in the filiform leaf segments but merge seamlessly with the remainder of var. glabriuscula.
Selected References
None.
