Two haplotypes of Capsella bursa-pastoris (Brassicaceae) in Continental Chile support multiple introduction
Shepherd’s purse (Capsella bursa-pastoris; Brassicaceae) is a global weed. In Chile, this species was introduced early during Spanish colonization, however, previous studies based on allozymes and RAPD fragments, show that populations in southernmost Chile could be related to England popul...

Shepherd’s purse (Capsella bursa-pastoris; Brassicaceae) is a global weed. In Chile, this species was introduced early during Spanish colonization, however, previous studies based on allozymes and RAPD fragments, show that populations in southernmost Chile could be related to England populations.
