I noticed these after my comments on your Trivia monarcha
I understand (by googling Sypha ciliata),that it's modern name is sycon ciliatum (Wikipedia,marlin, habitas etc all agree as does my Collins guide), so it'd be worth adding a 2nd id with 'uptodate name
Elsewhere I have suggested this might be misidentified. It isn't (in my opinion).
However Chris is right (AGAIN!) there is a name change and the ID needs changing to reflect this.

Oh and yes (now I know about these things) JoC is right too.
