We've just been in the field and have found a trefoil with a black leaf
and small yellow flower like a lesser trefoil. The leaf has absolutely
no green on it whatsoever. There's only one small clump that we could
see. Naturally, I didn't have the camera with me but will take a photo
tomorrow. Does anyone have an inkling of which type of trefoil this
might be?

Did you look at the flower closely? The reason I ask is that I
have been caught out by oxalis before now, and there IS a dark
leaved variety of that!
