Prop-roots – In some dome-shaped (deliquescent) trees, from the mature horizontal boughs (stem-branches) some quite thick (millimeters to centimeters) roots come down. After growing and reaching the ground, they establish more elaborate root branches as well as show massive secondary thickening. Thus, they start to resemble the main trunk.
Xanthorrhoea australis, the grass tree or austral grasstree, [1] is an Australian plant. It is the most commonly seen species of the genus Xanthorrhoea . Its trunk can grow up to several metres tall and is often branched.
Dendrolycopodium obscurum, synonym Lycopodium obscurum, commonly called rare clubmoss, [2] ground pine, [3] or princess pine, [4] is a North American species of clubmoss in the family Lycopodiaceae. [5] It is a close relative of other species such as D. dendroideum and D. hickeyi, also treelike.
The buttress roots can be clearly seen in photographs extending 12 to 15 m (40 to 50 ft) up the trunk of some specimens [11] and extending out from the trunk as much as 20 m (65 ft) and then continuing below ground to a total length of 50 m (165 ft) [12] [13] The trunk and many of the larger branches are often crowded with large simple thorns.

Fern moss covers the ground and there is a possibility of ground rot. In flat areas balsam fir grows fast, tall, and large, mixed with red spruce. Hardwood slope – ground rot is common in this well-drained area, and leaf litter covers the forest floor.
The roots of a tree serve to anchor it to the ground and gather water and nutrients to transfer to all parts of the tree. They are also used for reproduction, defence, survival, energy storage and many other purposes. The radicle or embryonic root is the first part of a seedling to emerge from the seed during the process of germination.
Buttress roots, also known as plank roots, are large, wide roots on all sides of a shallowly rooted tree. Typically, they are found in nutrient-poor tropical forest soils that may not be very deep. They may prevent the tree from falling over (hence the name buttress ).
