Wavy Bittercress

Cardamine flexuosaComing towards the end of March, there are still very few wild-flowers about, so I have been extra vigilant when out walking and spotted this tiny, inconspicuous white flower growing by the side of the road. It has proven rather difficult to identify as there are two, almost identical, varieties of bitter-cress. Following some research I finally figured out that the so-called “Hairy” bitter-cress is not actually hairy, while the “Wavy” bitter-cress is! So, as this tiny plant has noticeably hairy stems, I have deduced that it is the Wavy Bitter-cress, but if anyone has a better way of distinguishing between these plants, please let me know.
