Ambrosia chenopodiifolia
is a species of ragweed known by the common name San Diego Burrsage or San Diego Burr Ragweed. 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 flower cluster bearing heads of pistillate (female) flowers below a cluster of staminate (male) flowers. The flower cluster is spiny, especially when in fruit. The fruit is a spherical, woolly bur about half a centimeter long covered in hooked spines.
