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.
