Lepidodendron is an extinct genus of primitive lycopodian vascular plants belonging the order Lepidodendrales.It is well preserved and common in the fossil record. Like other Lepidodendrales, species of Lepidodendron grew as large-tree-like plants in wetland coal forest environments.
Lepidodendrales (from the Greek for "scale tree") or arborescent lycophytes are an extinct order of primitive, vascular, heterosporous, arborescent (tree-like) plants belonging to Lycopodiopsida. Members of Lepidodendrales are the best understood of the fossil lycopsids due to the vast diversity of Lepidodendrales specimens and the diversity in ...

It might be another tree’s branch, or it could be a fence rail nailed to the tree’s trunk. There’s a bicycle in Washington State that was hung on the side of a tree 75 years ago.
Most of the trees are mature and healthy when they begin to lose limbs because of extreme temperatures, though ITD has also had to remove dead trees along Idaho 55 that posed serious hazards to ...
The smelly trees are detrimental to our area’s wildlife. If you dig yours up, you can get up to 5 (different!) free trees.
Standing beneath the tree during rain can cause blistering of the skin from even a small drop of rain with the latex in it. Burning tree parts may cause blindness if the smoke reaches the eyes. The fruit can also be fatal if eaten. Many trees carry a warning sign, while others have been marked with a red "X" on the trunk to indicate danger.
During the Carboniferous, tree-like plants (such as Lepidodendron, Sigillaria, and other extinct genera of the order Lepidodendrales) formed huge forests that dominated the landscape. Unlike modern trees, leaves grew out of the entire surface of the trunk and branches, but fell off as the plant grew, leaving only a small cluster of leaves at ...
