What is "chaenorhinum"

Chaenorhinum is a genus consisting of about 20 species of annual and perennial herbs native to Turkey and the Mediterranean, where they thrive in dry stony areas and scree. They are closely related to snapdragons. The leaves are linear to oblong or rounded, opposite at the base. The flowers resemble snapdragons, being typically hooded, lobed and spurred. They are borne in terminal racemes or singly in the leaf axils of the branching stems.
