The Scrophulariaceae or figwort family is a large family of herbs and shrubs containing around 275 genera and 5000 species, and inhabiting areas from sea level to the tops of mountains from wetlands to deserts in mostly temperate areas. Currently the family is in a state of revision due to molecular studies, and may be radically different in the near future. The flowers have 5 sepals and 5 petals and the corolla is bilabiate. The fruit is most often a capsule and occasionally a berry. The family takes it name from genus Scrophula which in turn was named in 1474 by an Italian physician who noticed the resemblance between the rhizomal knobs of some species and the tubercular condition of human lymph nodes called scrophula. Some species in this family are root parasites like Castilleja and Orthocarpus, and the family includes monkeyflowers, snapdragons, penstemons, paintbrushes and digitalis.
