Layia pentachaeta
Layia carnosa
Subspecies 2 (2 in the flora).
Molecular phylogenetic data have indicated that Layia pentachaeta is closely related to L. glandulosa and L. discoidea (B. G. Baldwin, unpubl.). Distributions of L. pentachaeta and L. glandulosa overlap broadly; the two species occur in different habitats and natural hybridization has been rarely detected (first-generation hybrids are of low to moderate fertility; J. Clausen 1951).
