California damsonium, Fringed Water Plantain
Synonym(s): Machaerocarpus californicus
USDA Symbol: DACA12
USDA Native Status: L48 (N)
Several basal leaves and 1 or few flower stalks with white or pink, fringed flowers often in clusters on whorled branches. This was once considered the sole species in a small western American genus, Machaerocarpus. It has now been placed in a wide-ranging but still small genus, which also occurs in Eurasia and Australia.
Members of the Water-Plantain Family grow in water, in swamps, on muddy banks, or occasionally in wet sand. Each plant has long-petioled leaves in a clump with a flowering stem rising among them. The flowers have 3 green sepals, 3 white or pink-tinged petals, 6 or more stamens, and several pistils. Stamens and pistils may be in separate flowers.
