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 ...

The whole database contains materials from over 10,000 woody species and 200 plant families. Initiator for this wood anatomy database has been the American botanist and wood scientist Elisabeth Wheeler. The database contains two dinstictive menus for specific anatomical features of modern wood species: Softwoods [6] Hardwoods [7]
The following table associates tree species, wood name and wood colour. The Dipterocarp timber classification system was developed by Colin Fraser Symington (1905-1943), a forester at the Malayan Forestry Service, and H. E. Desch, who researched comparative wood anatomy.
Because this species has no insect or decay resistance qualities after logging, it is generally recommended for construction purposes as indoor use only (indoor drywall framing, for example). Spruce wood, when left outside cannot be expected to last more than 12–18 months depending on the type of climate it is exposed to. [51]
The wood moisture content is above 25% on a dry-weight basis; The environment is sufficiently warm; Oxygen (O 2) is present; Wood with less than 25% moisture (dry weight basis) can remain free of decay for centuries. Similarly, wood submerged in water may not be attacked by fungi if the amount of oxygen is inadequate. Fungi lumber/timber ...
The genus Quercus contains about 500 known species, plus about 180 hybrids between them. [1] The genus, as is the case with many large genera, is divided into subgenera and sections. Traditionally, the genus Quercus was divided into the two subgenera Cyclobalanopsis, the ring-cupped oaks, and Quercus, which included all the other sections.
