Definition: The word "amphicytula" refers to a genus of plants in the family Acanthaceae, commonly known as common thistles or wild fescue. They are small shrubs with spiky, scaly leaves that can grow up to 20 inches long and reach heights of around 6-12 feet. The definition of "amphicytula" involves plants in the Acanthaceae family that have a unique ability to form tight mats on other plants. This is known as an intertidal or interstratum effect, where they create a protective cover for their own roots and shoots against grazing animals. Amphicytulas are commonly found growing alongside other grasses, weeds, and native plants in temperate regions around the world, often forming dense mats on bare soil. They are also used as fodder, hay, and food plants by some livestock feeders.
