Antirrhinum sp is a genus of plants commonly known as snapdragons from the flowers’ fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed (thus the 'snap'). The antirrhinums used to be treated as the family Scrophulariaceae, but studies of DNA sequences have led to the inclusion of Antirrhinum in a vastly enlarged family Plantaginaceae. The word "Antirrhinum" is derived from "antirrhinon" which in turn was derived from Greek anti "like" and rhis "nose", inus  "of" or "pertaining to". The name literally means "like a nose" in and probably refers to the nose-like capsule in its mature state.
