silky oak / Grevillea robusta
(other species also shown on this page)
Grevillea robusta of the family Proteaceae. There is some confusion around this name, but my own samples were sold to me as Grevillea robusta, if any botanical designation was given, and the Wood Book (see below) lists silky oak as Grevillea robusta. For a discussion of the name confusions, see the link below the composite pic.
5" x 5" flat cut, 5" x 5" quartersawn, 1" wide end grain, and a 1/4" x 1/4" end grain closeup.
There are at least 40 other species from over 20 other genera that have "sliky oak" as all or part of one or more of their common names and some of them are included on this page including blush silky oak / Bleasdalea bleasdalei, briar silky oak / Musgravea heterophylla, and brown silky oak / Darlingia darlingiana.
Diffuse porous with obvious scaliform parenchyma. Rays vary in size but are generally very wide and easily visible with the naked eye. Ray flakes on quartersawn surfaces are small to quite large (this pic alone shows a decent spread of sizes)
Because of the large ray flakes that it sometimes has, this wood is sometimes called lacewood although it would never be confused with true lacewoods (more about that in the link directly below). Also, it COULD be confused with sycamore by an inexperienced viewer. This wood is moderately light, easy to work, and has a pleasing grain pattern.
In Hawaii, this wood often goes by the name "silver oak"
