Capsella: A Versatile Genus
The genus Capsella, belonging to the mustard family (Brassicaceae), encompasses several interesting plant species. Notably, this genus is closely related to Arabidopsis, Neslia, and Halimolobos.
Taxonomy and Nomenclature
- Genus: Capsella
- Family: Brassicaceae (Mustard family, also known as Cruciferae)
- Class: Magnoliopsida (dicotyledons)
- Subclass: Dilleniidae
- Order: Capparales
Species Highlights
- Capsella bursa-pastoris: Commonly known as shepherd's-purse. Synonyms include Capsella rubella Reut. and Thlaspi bursa-pastoris Linn.
- Capsella rubella: Known as pink shepherd's-purse.
Distribution and Habitat
Capsella bursa-pastoris, initially a European mustard, is now a widespread exotic species found in many parts of the world. It is considered a cosmopolitan weed of temperate regions, even appearing in cooler climates. It thrives in disturbed areas and nutrient-rich habitats, including fields, lawns, and roadsides.
Morphological Characteristics
Capsella bursa-pastoris is an annual or biennial herb, typically growing to a height of 0.3 meters (approximately 1 foot), though it can range from 5 to 80 cm. It features erect stems and triangular, purse-like seed pods. Basal leaves form a rosette, reaching up to 9 inches across.
Ecological Role
Capsella bursa-pastoris is often considered a weed. It is an annual plant that germinates throughout the year under suitable conditions, readily colonizing waste ground.
Genetic Information
The genome of Capsella rubella has been sequenced. This species is particularly interesting due to its self-pollinating nature and recent divergence from the outcrossing species C. grandiflora.
Traditional Uses
Capsella bursa-pastoris has been traditionally used for medicinal purposes. The dried plant has been utilized, and information about its constituents, medicinal actions, and uses has been published.
