Elliott, Stephen. 1823. A Sketch of the Botany of South-Carolina and Georgia 2: 447-448. Elliott here on page 448 creates the genus name Actinospermum, indicating that the only species is A. multiflorum. Basionym is Balduina multiflora, as listed on Elliott's page 447. B. multiflora, in turn, is now considered a synonym of B. angustifolia according to The Plant List. Hence Actinospermum is a synonym of Balduina
