Mahonia is a genus of approximately 70 species of evergreen shrubs and, rarely, small trees in the family Berberidaceae, native to eastern Asia, the Himalaya, North and Central America. They are closely related to the genus Berberis and botanists disagree on whether to recognize a separate Mahonia. Many botanists prefer to classify Mahonia as a part of Berberis because several species in both genera are able to hybridize, and because there are no consistent morphological differences between the two groups other than the leaf pinnation. However, recent DNA-based phylogenetic studies retain the two separate genera, by clarifying that unifoliolate-leaved Berberis s.s. is derived from within a paraphyletic group of shrubs bearing imparipinnate evergreen leaves, which are then divided into three genera: Mahonia, Alloberberis, and Moranothamnus ; a broadly-circumscribed Berberis would also be monophyletic.

Mollugo verticillata, the green carpetweed, is a rapidly spreading annual plant from tropical America. In eastern North America, it is a common weed growing in disturbed areas.

Sometimes also referred to as "Indian chickweed", in China this plant is referred to as zhong leng su mi cao.
