Inflorescence of branched broomrape parasitizing Medicago lupulina in northeastern Texas. The relationship between these ruderal broomrape populations and those that parasitize cultivated tomatoes in California and Chile has been controversial, with some suggesting that they are a separate species. In “Multiple genotypes of Phelipanche ramosa indicate repeated introductions to the Americas”, Schneider determined that these three populations, as well as a fourth centered in Virginia, form distinct genetic groups that are probably the result of both separate introductions from Eurasia and gene flow between P. ramosa and its relative P. nana.
