Schismatoglottis Wallichi, aka Drop Tongue Plant, is another rare aroid with oblong-shaped foliage, each leaf containing wrinkles, or fan-like folds. As the leaves mature, the central, pale green marking actually expands to be a heart-shaped band surrounding the perimeter of each leaf. If you have a Chinese Evergreen or Homalomena and it is doing well, you will definitely be able to care for one of these beauties.
