I think I need to see a bit more of the plant...and maybe a scale to say for sure. The hairs onth e stem are clearly adpressed, but it's lower down the stem where this trait is most important!

Hairy indeed

With so much hair on the leaf, stem and sepals, this could be the field forget-me-not, but this is a variable species so I am not sure.

Myosotis spp.

For the uninitiated what Peter is (if I do not put words into his mouth!) referring to are the stem hairs which can be used to help distinguish between four Myosotis species - two have the lower part of the stem with patent hairs and appressed hairs elsewhere (M.secunda and M. alpestris) and two with appressed hairs throughout (M. stolonifera and M. laxa).

However a good first step (and the point at which most keys start) is to look at the calyx hairs - five species have straight appressed hairs, four have hooked or strongly curved hairs and one (M.alpestris) inconveniently can have either.

The specimen here has curved patent hairs which means we have one of five species - M. alpestris, M.arvensis, M.sylvatica, M. discolor or M. ramosissima. (and note that the issue with the lower stem hairs then ceases to be a problem). M. ramosissima is a tiny plant with bright (startlingly so) blue flowers which this plant does not so we're down to four. The fruiting calices on M. arvensis are on long pedicels - equal to or twice as long as the fruiting calyx. Although fruits are not well-developed here the pedicels look too short for M. arvensis. Unfortunately, the other three can look remarkably similar on a photograph. And without a scale to judge the size of the corolla (M.discolor has small flowers - about 2mm across) I don't think one can take this much further. It's not likely to be M. alpestris in Bulith Wells, unless it has a garden connection in which case anything's possible!

Incidentally the key in Stace works really well - I use it to teach beginners as one can normally get a result.

Unknown forget-me-knot

The plant was found in a boggy area with rushes and sedges; it is much smaller but I don't have a scale
I can't download a bigger picture due to size restrictions

I thought it may be changing forget-me-knot as the flowers open yellow and change colour to mid-blue it is also found in damp places, stalks are shorter than incurved sepals

M. arvensis- has pink flowers when young none here
M. ramosissima- very small flowers, leaves form a rosette
M. alpestris- Not in Wales
M. sylvatica- petals are longer than their tube, style longer than sepal tube, fruiting stalks longer than sepals, emerging flowers are also pink
