I'll try to only add to one thread this time! Any help would be much appreciated. Thanks! These are taken at wonderful Killinallan - an area of sand dunes on Islay. I've no idea about the first, but wondered if the other two are pale versions of the Autumn Gentian?

EDIT: I should add all these photos were taken in July a few years ago.

First I will have a stab at Heath Pearlwort Sagina subulata. The others I will leave, I am intrigued - distinct island form? I am mearly guessing and have no knowledge on such things

Autumn Gentian looks good Becky - frequent on sandy meadow/machair and cliff tops up there - and comes as a white form.
Cheers

I definitely go along with Autumn Gentian; 5 petals makes it not possible to be Field Gentian, (4 petals), which also grows in that lovely part of the world.

The small white flower has me guessing, Johns Heath Pearlwort is a possibility, but I don't see the normally very prominant sepals. A Spurrey is another poss., can't see a leaf which would help.

I'd go for knotted pearlwort, Sagina nodosa as flower is 'tall', petals longer than sepals and not notched.

Thanks guys. I'm happy with the Autumn Gentian but keep getting frustrated with these little white jobs! Becky
