Discussion

Of conservation concern.

Layia munzii occurs in the southern San Joaquin Valley and South Inner Coast Ranges. Populations are evident only in some wet years, when dense stands may be found, sometimes near L. platyglossa (natural hybrids have not been reported; artificial hybrids have reduced fertility; J. Clausen 1951).

Selected References

None.

Lower Taxa

None.
