Discussion

Layia platyglossa occurs from the North Coast Ranges through central-western and southwestern California and west to the immediate coast and east into the central Great Valley. A specimen reported by S. L. Welsh et al. (1993) from dunes in Utah (Harrison 2545, BRY) may be mislabeled.

Selected References

None.
