The word "ruellia" has its etymology rooted in the honor of French botanist Jean Ruel. The genus "Ruellia" was named by the Swedish botanist Carl Linnaeus in the 18th century, as a way to pay homage to Jean Ruel (Latinized as Joannes Ruelius). Jean Ruel was a physician and botanist who lived from 1474 to 1537. He was known for his work in botanical illustrations and herbal medicine, and his contributions to the field of botany led Linnaeus to name this genus after him.
