Cardamine flexuosa

Wavy bitter-cress (Cardamine flexuosa) is not easy to distinguish from hairy bitter cress (Cardamine hirsuta), but is generally larger, and found in wet locations.

By photographing possible specimens it is possible to distinguish the two species by means of counting the number of stamens (6 vs 4). The result is that in addition to the locality in parish A recorded last year, I have recorded plants on either side of the stream dividing parish L (Thursday) from parish O (today).
