Which genus contains more species, Asarina or Wigandia?
Asarina Asarina is a flowering plant genus of only one species, Asarina procumbens, the trailing snapdragon, which is native to southern Europe. Originally placed in the Scrophulariaceae (figwort family), the genus has more recently been moved to the Plantaginaceae (plantain family). Species from North America formerly placed in the genus "Asarina" are now placed in "Holmgrenanthe", "Lophospermum", "Mabrya" and "Maurandya", as well as "Neogaerrhinum". "Asarina" is now regarded as exclusively an Old World genus.
Talbotia elegans Talbotia elegans is the sole species in the monotypic genus of monocotyledonous flowering plants, Talbotia. The plant is a member of Velloziaceae family and it is closely related to another African genus which is "Xerophyta". That's why depending on the classification system these two genera are sometimes united together in "Xerophyta".
