Brunfelsia

About

Brunfelsia is a genus of flowering plants belonging to subfamily Petunioideae of the nightshade family Solanaceae. The 50 or so species have been grouped into the three sections: Brunfelsia, Franciscea and Guianenses, which differ significantly in both distribution and characteristics, although molecular data have revealed that only two sections are natural (monophyletic), namely the Caribbean section Brunfelsia and a common section for all South American species. Linnaeus named the genus for the early German herbalist Otto Brunfels (1488–1534).
