"Ambrosia chenopodiifolia" is a species of ragweed known by the common name San Diego bur sage. It is native to Baja California, and California as far north as San Diego County, where it is a member of the coastal sage scrub plant community. This is a thickly branching shrub exceeding 3 meters in maximum height. The leaves are ovals up to 3 centimeters long and coated in white hairs. They are sometimes lobed. Like other ragweeds it is monoecious, with each inflorescence bearing heads of pistillate (female) flowers below a cluster of staminate (male) flowers. The inflorescence is spiny, especially when in fruit. The fruit is a spherical, woolly bur about half a centimeter long covered in hooked spines.
