Free Field Guide to Violas, this weekend

Yes, iSpotters, yet again I am giving away a free Field Guide this is the one for Violets and Pansies, an interesting little group, not particularly difficult, but much easier with this Field Guide to hand:

As you can see, it's free all the time if you have Kindle Unlimited, but it will be free to everyone this weekend, 14th/15th March.

Here's the link to the Field Guide to Violets and Pansies. 

Do download it if it you get time, then get out there and find some Violets to botanise!!
