the REST of the pictures on this page will give you a better overall feel for this wood
Pacific yew / Taxus brevifolia
Also known as common yew, Oregon yew and western yew
3" x 3" flat cut, 2" x 2" quartersawn, 3/4" wide end grain, and a 1/4" x 1/4" end grain closeup.
This softwood has no resin canals. Swirly grain on the face is quite common and straight grain quartersawn is the exception rather than the rule. Identification of yew is mainly just by virtue of the fact that there aren't any other woods that look like yew. As to which particular species of yew a piece might be, well ...
Or as a friend of mine once put it, "The thing about yew is that it just never looks like me, it always looks like yew". (OK, he's not a close friend)
