# Ruellia

Ruellia est un genre appartenant à la famille des Acanthaceae. Il comprend environ 250 espèces de plantes herbacées.
Ce sont des plantes principalement originaires des régions tropicales ou subtropicales. Quelques espèces sont originaires des régions tempérées d'Amérique du Nord où elles sont communément appelées pétunia.
C'est Charles Plumier (1646-1704) qui dédie ce genre à Jean Ruel (v. 1479-1537), botaniste français. Carl von Linné a ensuite conservé cette appellation.
