Richardia

Richardia is a genus of flowering plants in the family Rubiaceae. The genus was first described in 1820. Species within this genus are native to South America, particularly Brazil. These plants are typically herbaceous perennials, often found in sandy or disturbed areas. They are characterized by their relatively small, star-shaped flowers, which are usually white or pale pink. The fruits are small capsules. Common species include Richardia brasiliensis, also known as Brazilian Richardia or white-flowered Mexican clover, and Richardia scabra. These plants can sometimes be considered weeds in agricultural settings due to their ability to proliferate. Despite this, they are also appreciated for their ornamental value in some regions. The genus name honors the botanist Richard. Further research into the genetic diversity and ecological roles of Richardia species continues.
