Cotula L.

Cotula is, as currently understood, a genus of ca. 50 species, mostly confined to the southern hemisphere (especially South Africa) (Mabberley 2008). About 30-40 species formerly included in Cotula and chiefly originating in Australia and New-Zealand, are now accommodated in a separate genus, Leptinella Cass. Several species of the latter genus are cultivated as ornamentals (especially for carpeting; Cullen 2000, Jäger & al. 2008) and have been reported as naturalised escapes in lawns in the British Isles (see for instance Sell & Murrell 2006; more recently also in Germany, see Dickoré & al. 2009). They might have been overlooked in Belgium. The genus Cenia Comm. ex Juss., formerly represented as a wool alien in Belgium (Verloove 2006), is now included in Cotula.
