Ctenanthe Burle-Marxii, aka Fishbone Prayer Plant, is a species of plant in the genus Ctenanthe native to Brazil. It has bright green leaves, striped with alternating lance-shaped bands, and deep purple undersides and stems. Ctenanthe, along with their close relatives Calatheas and Marantas, are commonly called "Prayer Plants" because of their habit of opening and closing its leaves as day transitions to night.
