Yup... Last printing was in '76, I think. A quarter century behind. :(

I like to use the RHS "Index of Garden Plants" by Mark Griffiths, although
I think that his familial delineations aren't quite right. That also
means that we differ on the naming of certain genera, too, but that's
OK. The book is good because it's got a ton of names (about 60,000) and
is affordable (about $42 at Amazon).

If you really want to do it right, I prefer Arthur Cronquist's book,
"An Integrated System of Classification of Flowering Plants." It
costs $225.00 at Amazon, but even at 8 years of age it's starting to
fall behind on the latest trends in naming.
