It seems Dove's-foot Cranesbill isn't common in the hectad and not yet seen after 2000 so we were pleased to find it on a raised area that looked like it had been quarried in the distant past:
Dove's-foot Crane's-bill, Pig yr aran or
Geranium molle
Nearby was this thistle which confused us at first but turned out to be one that hasn't yet been recorded for the hectad at all in the county and only before 2000 over the border in England (Herefordshire) - unless records are in the pipeline there, of course.
Musk Thistle,
Ysgallen Siarl
or
Carduus nutans
Apparently well behind in development this season but there were many rosettes for next year around.
And we found plenty of Pillwort - this must be one of the country's strongholds for this decreasing and rare fern. The ephemeral pools in the area were very deep resulting in very long fronds at quite a depth.
Pillwort,
Pelenllys gronynnog
or
Pilularia globulifera
Here is a close up of the unusual plant:
Temporarily beached in Radnorshire in 2011.
