Diagnostic characters
Cotula coronopifolia is easily distinguished from the other species, but some specimens from the Northern Cape with bipinnate leaves ( Fig. 4.G View Fig 3 View Fig ) may be confused with C. bipinnata . Cotula coronopifolia is, however, distinguished by the sheathing leaf bases, spongy stems, decumbent habit with rooting at the nodes ( Fig. 1.M View Fig ), and greater number of disciform florets (25–30) (leaf bases clasping, stems herbaceous, erect with spreading branches and fewer disciform florets (1–14) in C. bipinnata ). Cotula coronopifolia is also generally more aquatic and is found submerged in water whereas C. bipinnata occurs along the margins of seasonal pools.
Distribution, ecology and conservation status
C. coronopifolia is widespread in the Northern, Western and Eastern Cape, with isolated populations in Gauteng that may be naturalised ( Fig. 11 View Fig ). This species has also become naturalised globally, recorded also in North America, South America and Australia ( Cronquist, 1963; Cooke, 1986). It prefers the margins of freshwater or saline pools where it grows in clumps. However, smaller individuals are known to occur in waterlogged soils. This species is listed as LC.
