description_en: Genus of about 12 species of evergreen shrubs, subshrubs, and perennials from stony slopes and scrub in tropical and subtropical W. South America. The leaves are arranged in opposite pairs or in whorls of 3, on 4-angled, branching, slender shoots, and often alternately on the flowering shoots. Delicate, spurred, unequally 2-lipped, orange or red, sometimes white flowers are borne in spring and autumn in lax, terminal racemes. Use as colourful winter-flowering container plants in a temperate greenhouse or conservatory, as summer bedding, or in a mixed border. They also provide good cut flowers. Modern, compact-growing seed selections for bedding are now available. The species described are usually grown as annuals.
