Alonsoa (mask flower) is a genus of 12 species of flowering plants in the family Scrophulariaceae. The genus includes both herbaceous and shrubby species. The genus is native to Central and western South America, from Mexico south to Peru and Chile. At least two species are native to South Africa. Alonsoas grow to around 30–100 cm tall, and have small, broadly oval, serrated leaves. The red, orange, yellow, white or occasionally blue flowers are borne on a loose terminal raceme. The alonsoa is named for Zenón de Alonso Acosta, a Spanish official in Bogota.
