There's usually a theme - last week, it was mostly twigs from trees, and this week it was mostly ivies (that's a clue, by the way). I won't inflict the whole 11 idents on you, but here's a choice selection - can you recognise any of these? (I'll give you a clue for the more difficult ones).
(Clue: yes it is meant to be up that way.)
2. (Clue: it's changed its name recently - and you'll have to come up with the new one!)
3. (I'm not going to give you a clue for this one - far too easy!)
4. (Clue: this is a juvenile shoot)
(Clue: it's all in the stem colour)
There aren't any prizes, beyond the right to be smug, though I might keep a running total and come up with a little something for the person who gets the most right between now and when this little series finishes, in about June. But for now, let the guessing begin - first person to guess correctly has the point, and if you haven't got them all by next week, I'll give you the answers in the comments section. Have fun!
