Description:

Have to confess that Violas totally confuse me and I'm not very confident of this one. It was growing among acidic loving grasses and other plants on St. Boniface Down.

they confuse me too

every time I think I'm beginning to get a grip on identifying them, one comes up that confounds me (like yesterday on Newmarket Heath).

But I'd go for with V riviniana for this one too, as well as the other features, the petals are very rounded, not like the rabbit's-ears of V reichenbachiana. But I could easily be wrong!

Well David I have to agree

Well David I have to agree with you violets are also one of those groups (there are plenty on my list) that I am never totally confident with especially in photos, the stout, straight, notched spur in your last photo says riviniana to me.

The pdf of the BSBI Plant

The pdf of the BSBI Plant Crib on Viola is freely available and one of the authors (Tim Rich) is available on iSpot to help out.

You cant just take a flower picture and hope to have enough characters.

Sepals - pointed or not
Habit - Basal rosette or all leaves on stem
Leaves - shape and hairiness
Stipules - nature of teeth on the stipules
Flowers - spur colour and notched or not

We only have 2/5 of these presented here.
Viola canina can have a stout yellow notched spur. Basal rosette present and stipule teeth slender pointed sideways will say it is V. riviniana.
