Xanthostemon verdugonianus, commonly known as mangkono or Philippine ironwood, is a species of plant in the family Myrtaceae. [2] It is endemic to the islands of the Visayas, Palawan, and northeastern Mindanao. It is valued for its extremely durable and heavy timber. It is threatened by habitat loss.
Ironwood is a common name for many woods that have a reputation for hardness, or specifically a wood density that is denser than water (approximately 1000 kg/m 3, or 62 pounds per cubic foot), although usage of the name ironwood in English may or may not indicate a tree that yields such heavy wood.
Seri ironwood carving. Mexican ironwood carving is a Mexican tradition of carving the wood of the Olneya tesota tree, a Sonora Desert tree commonly called ironwood (palo fierro in Spanish). Olneya tesota is a slow growing important shade tree in northwest Mexico and the southwest U.S. The wood it produces is very dense and sinks in water.
Olneya ironwood is very hard and heavy. Its density is greater than water and thus sinks; it does not float downstream in washes and must be moved by current motion. Due to its considerable hardness, processing desert ironwood is difficult. Final treatment of the wood with solutions can also be difficult because of its high density.
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
Krugiodendron ferreum, commonly known as the black ironwood or leadwood, is a species of tree in the family Rhamnaceae. It is found in southern Florida, throughout the Caribbean and from southern Mexico to Honduras. [2] Originally described by Martin Vahl, its specific epithet is the Latin adjective ferreus ("iron-like"). [3]
The common English name hornbeam derives from the hardness of the woods (likened to horn) and the Old English beam, "tree" (cognate with Dutch Boom and German Baum).. The American hornbeam is also occasionally known as blue-beech, ironwood, or musclewood, the first from the resemblance of the bark to that of the American beech Fagus grandifolia, the other two from the hardness of the wood and ...
The fruit is a pair of hard follicles. In natural populations on the islands the tree grows in distinct groves. Isozyme analysis has determined that each grove is a clonal colony in the landscape. [1] Each ironwood clone, or genet, is a group of genetically identical individuals comprising a dozen to several hundred tree trunks, or ramets.
