Tree and nature ID book and Camera ideas for present for 10 year old

Didn't know where the best place would be to post this...

Looking for a good tree and plant ID pocket type book for my 10 year old for a present.

She likes nature and the environment and I when i take the family for walks in local forests/ parks I often get asked what's this tree/ what's this plant?
I am starting to struggle once we move beyond the common ones that most people know.

So I want to get her a small, concise and easy to use identifier to cover trees and plants of Ireland.
She also wants to take photographs of nature (and other things as well). She has mentioned a camera phone but I am not giving in to that for at least another 5 years or so. Any suggestions on a cheap and cheerful digital camera for that age?
I looked at the recently released Polaroid ones but the cost of the film would turn me off it (nearly €2 a pic I reckoned)
I have a small printer for printing photos from my wifes phone so she could use that when she needs to print one which is why I am thinking digital.
