The new genus Ignurbia of the Asteraceae tribe Senecioneae is described from the island of Hispaniola in the Caribbean. Its only species, I. constanzae, first described by Ignatz Urban under Senecio, is illustrated. The new genus is characterized by its herbaceous, suffruticose habit, dissected leaves with a herbaceous texture, orange or dirty yellow discoid capitula and styles with continuous stigmatic areas lacking distinct sweeping-hairs. Possibly related genera are Odontocline (Jamaica), Jessea (Costa Rica, Panama) and Talamancalia (Costa Rica, Panama, Ecuador, Peru).
