Their function is unknown, but they are generally seen on trees growing in swamps. Some current hypotheses state that they might help to aerate the tree's roots, [ 1 ] create a barrier to catch sediment and reduce erosion, assist in anchoring the tree in the soft and muddy soil, or any combination thereof.
They often constitute early successional species of their landscapes. Roots are shallow and wide spreading; lateral root growth in a forest may be as far as 60 feet (18 m). [4] Generally, four to five lateral roots originate from the tree, and then branch within 2 feet (60 cm); vertical, penetrating roots near the base anchor the tree.
Tree Roots is an oil painting by Vincent van Gogh that he painted in July 1890 when he lived in Auvers-sur-Oise, France. [ 1 ] [ 2 ] The painting is an example of the double-square canvases that he employed in his last landscapes.
The tests to demonstrate this networking are performed by injecting chemicals, sometimes radioactive, into a tree, and then checking for its presence in neighbouring trees. [57] The roots are, generally, an underground part of the tree, but some tree species have evolved roots that are aerial. The common purposes for aerial roots may be of two ...

For example, in the Eastern tropical forests of Madagascar, many lemurs achieve higher mobility from the web of lianas draped amongst the vertical tree species. Many lemurs prefer trees with lianas because of their roots. [2] Lianas do not derive nutrients directly from trees but live on and derive nutrients at the expense of trees.
The roots are shallow, widely spread, and send up suckers. [12] The numerous stems per plant become scaly with age. The tree has a crown width and height of 10 feet at maturity. [16] The branches are thorny. The leaves are alternately arranged, with an oval shape. The leaf length is usually 5.1–10.2 centimetres (2–4 inches) long.
