Avens above that ain't Wintercress

Guess who this garden visitor is?

In the Garden or in the wild there is one leaf I have been focusing on recently:

Country path

For a start I thought it was a perfect match with Wintercress (Barbarea vulgaris) but it turns out to be Wood Avens - Geum urbanum.  The confusing issue is that the winter rosette terminal leaves are rounder than the later terminal leaves which are more clearly three lobed (not unlike strawberry leaves).  Smaller opposite leaf pairs appear down the leaf stem :

Researching the internet the clincher is that a cress being a brassica has a four leaf yellow flower whereas Wood Avens  (a member of the rose family) has a five petal yellow flower and then a characteristic burr seedhead.  I don't need to wait for flowering as these burrs are all to familiar in our garden each summer.  If I needed further proof I could taste the leaves  (neutral for avens, peppery for cress) The root of Wood Avens is said to smell strongly of cloves, perhaps leading to its reputation as a remedy for both dog and snake bites.  Herb Bennet!
