Trifolium macraei is a species of clover known by the common names Chilean clover,[1] double-head clover, and MacRae's clover. It has a disjunct distribution, occurring on the coastline of Oregon and California in the United States, as well as in South America.[2] It grows in coastal habitat, such as sand dunes, and disturbed areas. It is an annual herb taking a decumbent or erect form. The leaves are made up of oval leaflets 1 to 2 centimeters in length. The inflorescence is usually made up of two oval or rounded heads of flowers each measuring up to 1.5 centimeters wide. Each flower has a calyx of sepals which taper into densely hairy bristles. The flower corolla is purple or bicolored with white or pink.
