![]() Most maples are trees growing to a height of 10–45 m (33–148 ft). The oldest fossils of Acer in Europe are from Svalbard, dating to the late Eocene ( Priabonian ~38–34 million years ago). The oldest known fossils of Acer are from the late Paleocene of Northeast Asia and northern North America, around 60 million years old. The closest relative of Acer is Dipteronia, which only has two living species in China, but has a fossil record extending back to the middle Paleocene in North America. Many maple species are grown in gardens where they are valued for their autumn colour. It is one of the most common genera of trees in Asia. Maple syrup is made from the sap of some maple species. The closest relatives of the maples are the horse chestnuts. Maples usually have easily recognizable palmate leaves ( Acer negundo is an exception) and distinctive winged fruits. The type species of the genus is the sycamore maple, Acer pseudoplatanus, the most common maple species in Europe. Only one species, Acer laurinum, extends to the Southern Hemisphere. There are approximately 132 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. The genus is placed in the family Sapindaceae.

For most trees, the stained bark is as bad as it gets. Is bacterial wetwood harmful?ĭamage done by bacterial wetwood depends on the condition of your tree. But, since so many different bacteria can spark wetwood, it can also happen to lots of other trees. Yes, bacterial wetwood is most common in maple, elm, oak, poplar and birch trees. Are maple trees more likely to leak clear liquid? ![]() As it drips down, it stains the tree's trunk a yellow or dark brown. The liquid starts out thin and transparent, then becomes a slimy, smelly ooze. Pressure mounts, and eventually runny liquid seeps out through openings in the bark. Once inside, the bacteria produce gas within the tree. Wetwood-causing bacteria enter trees through wounds in the roots, trunk or limbs. It's a disease that works its way into tree wood and spills out in the form of thin, water-like liquid. You can thank bacterial wetwood, also known as slime flux. Why is water leaking, falling, oozing or gushing from my tree trunk? (Slime flux) What we can do is make sure our trees are healthy enough to survive a wetwood infection.
