KT, Re adding species of flowers. If you go to the U.K. Wildflower Encyclopedia page - click on "wildflowers" on bottom left side of the page in the column under your user name - you can then add new species.
Thanks Jack, been in Canada for the last two weeks - loads of great flowers including 21 species of orchid (5 of those Lady's-slippers). I will do a bit of research and see what I can come up with for the Italian plants. It might be worth trying out Wild About the World to upload the rest. It's not too different from this site.
