Acacia usually grows to the height of 40 feet. Some types of acacia can reach 70 feet in height and 3 feet in diameter.
Most species of acacia have green, pinnate leaves. They are densely arranged on the branches and create impression of a giant fern. Species of acacia that grow in arid conditions have reduced leaves that consist only of vertically flattened leaf-stalks (without leaf-blades).
Non-Australian types of acacia are covered with sharp thorns (modified branches or leaf-stipules). Thorns protect plants from the hungry herbivores.
Swollen-thorn acacia (African species) lives in symbiosis (mutually beneficial relationship) with stinging ants. Acacia provides shelter (ants live inside the thorns) and food (they eat nectar). In return, ants protect plant from the herbivores.
