Acer is a genus of trees or shrubs commonly known as maple. Maples are variously classified in a family of their own, the Aceraceae. There are approximately 128 species, most of which are native to Asia, with a number also appearing in Europe, northern Africa, and North America. Most maples are trees growing to 10–45 m (33–148 ft) height.
A maple leaf is on the coat of arms of Canada, and is on the Canadian flag. The maple is a common symbol of strength and endurance and has been chosen as the national tree of many countries including Canada. Maple leaves are traditionally an important part of Canadian Forces military regalia, for example the military rank insignia for generals use maple leaf symbols.
Maples are important as source of syrup and wood. Dried wood is often used for the smoking of food. Charcoal from maples is an integral part of the Lincoln County Process used to make Tennessee Whiskey.They are also cultivated as ornamental plants and have benefits for tourism and agriculture.
Some of the larger maple species have valuable timber, particularly Sugar maple in North America, and Sycamore maple in Europe. Sugar maple wood — often known as "hard maple" — is the wood of choice for bowling pins, bowling alley lanes, pool cue shafts, and butcher's blocks. Maple wood is also used for the manufacture of wooden baseball bats, though less often than ash or hickory due to the tendency of maple bats to shatter when broken.

Intsia bijuga is a species of flowering tree in the pea family,The tree has a variety of common names including ipil, merbau and kwila.

The bark and leaves of the ipil are used in traditional medicines. The tree's timber, called merbau or kwila, is a very durable and termite-resistant wood, making it a highly valued material for flooring and other uses. The wood can also be used to extract a dye. Merbau can contain a "gold" fleck that runs through the grain, considered to be attractive by some.

The wood is used for flooring in U.S. and European markets where it is commonly sold under different names.

Sucupira applies to Bowdichia nitida from northern Brazil, B. virgilioides from Venezuela, the Guianas, and Brazil. The heartwood of sucupira is chocolate-brown, red-brown, or light brown (especially in Diplotropis purpurea).

The texture of the woods is coarse and uneven, and the grain can be interlocked. The density of air-dried wood of these species ranges from 720 to 960 kg/m3 (45 to 60 lb/ft3), which makes them generally heavier than true hickory (Carya). Their strength properties are also higher than those of true hickory. The heartwood is rated very durable to durable in resistance to decay fungi but only moderately resistant to attack by drywood termites.

Sucupira is ideal for heavy construction, railroad crossties, and other uses that do not require much fabrication. Other suggested uses include flooring, boat building, furniture, turnery, tool handles, and decorative veneer.
