Capsella is a genus of herbaceous annual and biennial plants in the family Brassicaceae. [2] It is a close relative of Arabidopsis , Neslia , and Halimolobos . [3]

Contents

Some authors circumscribe Capsella to contain only three species: Capsella bursa-pastoris , Capsella rubella and Capsella grandiflora . [3] As of 2025, Kew's Plants of the World Online list eight species. [1]

Capsella rubella is a self-fertilizing species that became self-compatible 50,000 to 100,000 years ago. Its outcrossing progenitor was Capsella grandiflora. In general, the shift from outcrossing to self-fertilization is among the most common transitions in flowering plants. Capsella rubella is studied as a model for understanding the evolution of self-fertilization. [4] [5]

The name is said to derive from Latin capsa, a box or case, alluding to fruit resembling a medieval wallet or purse; [6] the suffix -ella denotes "lesser". [7]
