Ant Plant

Ant plants are a group of tropical and subtropical epiphytic plants found in Southeast Asia, Africa, and the Americas that are named for and inhabited by ants. The symbiotic relationship between the ants and the ant plant is known as inquilinism, which is based on the ants gaining protection and a food source while providing nutrients and increased water efficiency for the host plant. Most species of ant plants form hollow, swollen stems where their ant roommates build their nests. A few genera, such as Hydnophytum and Myrmecodia, form hollow, fused stems containing multiple compartments, and still others have hollowed thorns that may be inhabited by ants. Ant plants are appreciated for their curious form and their association with the industrious ants.
