Browallia

Browallia is a small genus of seven species of flowering plants (mostly annuals though occasionally shrubs or ephemerophytes) belonging to the nightshade family Solanaceae. It is named after Johannes Browallius (1707–1755), also known as Johan Browall, a Swedish botanist, physician and bishop. The genus is closely related to the monotypic genus Streptosolen, the single species of which was published initially under the name Browallia jamesonii.

Browallia species are found from southern Arizona in the north, southward through Mexico, Central America and the Antilles to andine South America, reaching as far south as Bolivia.
