Dithyrea (shieldpod) is a small genus of flowering plants in the family Brassicaceae containing only one or two species.^[1] The California shieldpod or spectacle-pod, Dithyrea californica, is an abundant and unique-looking herb native to the southwestern United States and northern Mexico. The beach shieldpod, Dithyrea maritima, a rare plant found only on the coast of California and Baja California, is sometimes considered a subspecies of D. californica.^[2]
