We spied what looked like a very pale and sickly looking Geranium robertianum growing from one grike of the Limestone pavement but as we got closer it looked perfectly healthy but much, much paler than the ones we usually see in England. It turned out to be ssp celticum which is known to grow here and in South Wales. The flowers usually have red or purple anthers which you can hardly see, and hairy fruits as opposed to the glabrous or sparsely hairy ones on normal G. robertianum
