These small plants I found growing on the wall of our local 14th century castle. The plants do not receive direct sunlight.
SOLVED: Could this little plant be Anogramma leptophylla?
Here is a link to Aquilegia vulgaris L., which grows all over Italy:
I see that Anogramma is a fern. . . There is no columbine-like foliage in photos 3 and 4. I'm guessing the columbine-like foliage in photos 1 and 2 is either a columbine growing right next to the putative fern, or the fern has some foliage stages that resemble columbine.
Right, now that I look at the photos again, there definitely are several distinct plants, one of which might be Aquilegia.
In the background there is Adiantum capillis veneris. These leaves, of course, could belong to a Chelidonium majus, more likely than an Aquilegia. see photo. I am still betting of a member of the Fern family. Aquilegia sp., being quite common in the region where I live, I know the plant well. It is not the habit of Aquilegia sp. to grow on walls, but on the edges of roads or woods, where there is to be found a rich soil.
Cannot determine which of these two families this plant belongs. Pteridaceae or Polypodiaceae. I have searched Google images and the only plant I could find that is practically similar is: Pteridaceae..Cryptogramma crispus. This plant is not is not to be found in the region where the photograph was taken. Could even be a Botrychium sp.?
Are you talking about the plant in the photo you posted on 11/17/13, or the ones at the top from 11/16/13?
Hi Spoonlegs, I refer to the 4 images posted on 11/16/2013. Crypogramma crispus is practically identical to the plant on the 4 images. But as I mentioned before, dispersion of this plant doesn't include the Region Campania.
