Capsella is a genus of herbaceous plant and biennial plants in the mustard family Brassicaceae.[1] It is a close relative of Arabidopsis, Neslia, and Halimolobos.[2]

Some recent authors circumscribe Capsella to contain only three species: Capsella bursa-pastoris, Capsella rubella and Capsella grandiflora.[2]

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.[3][4]
