This is a relatively newly described ant plant. A linear-leaved epiphyte known to come from Sabah, Malayasia. This caudiciform is a member of the family Rubiaceae which include coffee and gardenias. The leaves are leathery and have narrow branches. There are tiny openings in the caudex which leads to a labyrinth of interior chambers.
In nature this plant maintains a symbiotic relationship with a certain ant which protects the plant from predators. In cultivation there are no native ants that are attracted to the plant.
Keep the plant warm and humid as well as the media -- moist but not wet. Grow it in medium to bright light but not in full sun. Pot it in a well draining media. A hanging basket is ideal for growing this unusual plant.
