Ornithopus pinnatus, the orange birdsfoot, is a plant in the Fabaceae family. It was first described as Scorpiurus pinnata in 1768 by Philip Miller in The Gardeners Dictionary.[1] In 1907, George Claridge Druce assigned it to the genus Ornithopus.
It is native to Western Europe, the Mediterranean Region and Macaronesia but is found elsewhere as an introduced species.[2] [3]
