I know almost as little about flowers as I do about birds.

I don't know the name of this Orchid.
I photographed it during a walk up into the
Cairngorm mountains

I don't know the name of this one either.  I photographed it on Iona.  The colour is right to be the Northern Marsh Orchid, but I'm not sure the flowers are right, nor do I remember where it was growing.

This is, I believe, a Fragrant Orchid,
Gymnadenia conopsea

This is Cotton Grass,
Cyperaceae eriophorum,
photographed on the Cairngorms.

This is a sedum, but I don't know which particular one.  It was growing over rocks and scrubby areas on the slopes of the Cairngorms.
