[Louisa Rogoff Thompson <louisagardener@earthlink.net>]

Rather than investing in a botanical dictionary, check any good 
unabridged dictionary.  Older editions are more likely to devote space 
to botanical terms than the newest ones, which have had to make room for 
large numbers of terms from the new technologies.  I'd recommend 
Webster's 2nd unabridged or the compact Oxford English Dictionary - your 
local library will surely have one or the other.
