In 2004 research into the molecular systematics of this group and related species by Oyama and Baum confirmed that the genus sensu lato as described by Thompson is monophyletic, provided that one species ( A. (For a comparison of Thompson with earlier systems, see Oyama and Baum, Table 1.) New species also continue to be discovered (see e.g. While many botanists accepted this broad circumscription ( sensu lato), whose main departure from other classifications was the inclusion of the New World Saerorhinum, others did not, restricting the genus to the Old World. ![]() Ī widely accepted scheme (Thompson 1988) placed 36 species in the genus in three sections. As of April 2017, The Plant List (Version 1.1) accepts 21 species. The USDA Plants Database recognises only two species: A. majus (the garden snapdragon), the only species naturalised in North America, and A. bellidifolium (the lilac snapdragon), now considered to be Anarrhinum bellidifolium (L.) Willd. The situation is further complicated by the variety of terms in use for infrageneric ranks, especially of the Old World species, that is Antirrhinum, sensu stricto (e.g. In particular the exact circumscription of the genus, especially the inclusion of the New World species (Saerorhinum), is contentious. The taxonomy of this genus is complex and not yet fully resolved at present. The genus is characterized by personate flowers with an inferior gibbous corolla.Īntirrhinum used to be treated within the family Scrophulariaceae, but studies of DNA sequences have led to its inclusion in a vastly enlarged family Plantaginaceae, within the tribe Antirrhineae. The Antirrhinum is morphologically diverse, particularly the New World group ( Saerorhinum). It is widely used as an ornamental plant in borders and as a cut flower. They are native to rocky areas of Europe, the United States, Canada, and North Africa. Antirrhinum is a genus of plants commonly known as dragon flowers, snapdragons and dog flower because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. ![]()
