The genus name means: from the Greek: early name for aromatic plants; the mythic food of the gods

This plant produces a pollen, when carried by the wind can produce high allergic reactions.

Stems are greenish when young and grayish when mature. The fruit of this plant is called a bur and is sticky (has spines). It is native to California, but also grows elsewhere.
