Xanthum (Lesser Burdock): From the Plant and Flower Alphabet


Xanthum (Lesser Burdock)

Xanthium strumarium (rough cocklebur, clotbur, common cocklebur, large cocklebur, woolgarie bur) is a species of annual plants of the family Asteraceae. Some sources claim it originates in southern Europe and Asia, but has been extensively naturalized elsewhere. Others, such as the Flora of China and Flora of North America, state it originates in the Americas but was an early introduction to Eurasia.

The species is monoecious, with the flowers borne in separate unisexual heads: staminate (male) heads situated above the pistillate (female) heads in the inflorescence. The pistillate heads consist of two pistillate flowers surrounded by a spiny involucre.
