Serradella (Omithopus) is a genus of annual pasture legumes native to the Mediterranean region and central and north-west Europe. There are five main species of serradella, three of which have been commercialised in Australia: yellow serradella, slender serradella and French serradella. Yellow serradella is the most common and widespread of all the species of serradella in the wild.
