It can be tricky to identify or specify a particular wood if you’re not very knowledgable about working with it. There are hundreds of different species available and even though a small number of those are in common usage in the construction trade, narrowing it down to the ideal look you want can be frustrating.
For many years a Production Designer was able to just hand a Scenic Painter a photograph and the artist would “grain” the surface to match any kind of wood they wanted. With the loss of painters who are trained in “graining”, it has become more common to find a laminated material which matches their choice or to use actual wood veneer that matches the reference.
One website that I’ve found recently is a very good starting point to locate a match to a reference photo you might have or select a wood species based on your preferences of shade, color, or grain.

The Wood Database was created by Eric Meier in 2007 and now includes images and data for over 600 different wood species. You can search by name, type, location, appearance, and several other catagories.

Each species entry has a color photo of the wood showing grain pattern (depending on the cut orientation) as well as the scientific data as to hardness and shrinkage rates.
The information is also available in hardback book form, which can be ordered from the site, which features the data on over 350 wood types, including large color images of each species.
There is also a wood identification guide section on the site to take you through the steps of making an identification.
Another good reference is a book called What Wood Is That? by Herbert Edlin. The book explains basic wood characteristics and details 40 common wood types. It also includes 40 actual wood samples so that you can see a real-life sample of the types outlined.

For larger wood samples to look at, I’d suggest getting a set of veneer samples like the ones below. You can find sets like the one below from various venders on Amazon. Be sure that you get a set that have labels attached for easy identification. With these, you have a piece large enough ( they are usually about 6″ x 12″) to be able to try different stains, finishes, or age to your liking.
