A typical mature tree 30–50 m tall has a root system that extends horizontally in all directions as far as the ...
Buttress roots. Jensen's Crossing near Cooktown, Australia. 1988. Buttress roots, also known as plank roots, are large, wide roots on all sides of a shallowly rooted tree.

The latter become the primary tissues of the root, first ...
