American wild carrot, also known as rattlesnake
weed, is a simple to few-branched annual that grows to 2' tall. The
stems are retrorsely-hispid, and the leaves are alternate, pinnate and
compound on stems to 6" long. The umbellate flowers are
subtended by bracts and there are five white petals and five stamens.
The fruit is oblong with two rows of stiff bristles. A common
species on dry slopes below 5000', mostly rocky to sandy places in coastal
sage scrub, chaparral and southern oak woodland, especially after fires
or other disturbances, American wild carrot blooms from April to June.
There is only one other member of the genus Daucus in Calif.
It is introduced, and is the plant that most people would recognize
as Queen Anne's Lace (Daucus carota) if they saw it as a flowering
weed out in a disturbed area, but which in fact is also the domestic
carrot. This picture was taken on the Chaparral Trail in Malibu
Creek State Park.
