pic 1 looks like Wavy Bittercress while pics 2 and 3 do look like Hairy Bittercress. Are the pictures of the same plant?
Please see my Flickr photo's www.flickr.com/photos/129804972@N07/
Photo 1 and 3 are definitely the same plant taken at the same time.Photo 1 may be a bit wavy where I have bent it to take a photo.
As you probably know, one way to tell C. hirsuta from C. flexuosa is to count the stamens. C. hirsuta usually has four and C. flexuosa usually has six. Pic 1 looks to have rather too many stamens for C. hirsuta.

Thanks.I did not know about the stamens,when the rain stops I'll go and count.
All three pictures look to be of Cardamine flexuosa.
