The a good starting point is the FPL/CSIRO searchable database at
<http://www.fpl.fs.fed.us/search/commonname_request.php . If there
isn't a tech sheet listed for a particular item it's probably not traded
commercially in any significant quantity. The search engine on that
site sucks though--entering "cherry" will not find the common US
commercial species, but "black" or "black cherry" will.
By the way, FPL will identify several samples a year for a US citizen at
no charge--details at
<http://www.woodworkerssource.com has datasheets and photos for a wide
range of species, some of which they also have in stock for sale.
