In crags just below the summit I saw and photographed what I took to be an undersized Starry Saxifrage (Saxifraga stellaris). It never occurred to me until after I had returned home, that it could be the much rarer Alpine Saxifrage (Saxifraga nivalis), though it didn't quite match the descriptions in the books, and I had never seen this species before.
I returned with the botanist responsible for maintaining the records for the area as he had an old record for this species on this hill. Unfortunately there had been a lot of rain and it appeared that the plant had been swept away, so we were never able to come to a definite conclusion.
Last week after I had been up Ben Dorain, I posted the image below on this blog, to show what I took to be Roseroot (Sedum rosea), Scurvygrass (Cochlearia sp.) and Starry Saxifrage (Saxifraga stellaris). I had taken it to help in the identification of the Cochlearia species, and sent it to the same botanist.
After I had sent it, I had a closer look at the picture. The little saxifrage on the right didn't look quite right. I sent the full-size image of it to the same botanist who confirmed that this time it really looked like Alpine Saxifrage (Saxifraga nivalis).
I could scarcely believe that, having made the mistake once of failing to notice this species, I had managed to do so yet again, and had to confess this to the same botanical recorder on both occasions!
