Xanthium Definition from Encyclopedia Dictionaries & Glossaries

Wikipedia English - The Free Encyclopedia
Cocklebur
The Cockleburs (Xanthium) are a genus of flowering plants in the family Asteraceae, native to the Americas and eastern Asia.

They are coarse, herbaceous annual plants growing to 50-120 cm tall. The leaves are spirally arranged, with a deeply toothed margin. Some species, notably X. spinosum, are also very thorny with long, slender spines at the leaf bases.

The flowers are of two types; One, in short terminal branches, produces only pollen. The other, in clusters in the axils of the leaves, produces seed.
