At the weekend I found what I take to be the hybrid between a none native species Arum italicum subsp. italicum and a native species Arum maculatum. As far as I can tell this is a new hybrid for Wales. Growing on a road verge with both parents north of East Aberthaw, Glamorgan. In the picture above is the leaf of the hybrid. Below can be seen both parents and the hybrid. The hybrid has yellowish veins and some of the leaves have black spots. Arum italicum has white veins on the leaves and no black spots. Have posted some leaves of the hybrid to Wisley where they will do DNA test on my specimens. Now I have to wait to see if science agrees with my field observation!
Had a very successful BSBI walk along a stretch of the River Ely to look for Chrysosplenium alternifolium (Alternate-leaved Golden-saxifrage), which was re-found for the county last year. The Chrysosplenium was found in three monads. There was eight of us on the walk, we recorded 168 species, very good going for this time of year.
I have started looking at the colour varieties of Sweet Violets as they are now starting to flower. Came across a large stand of this pinkish-purple form today called Viola odorata var. subcarnea. The purple and white forms are the common colour I normally see in Glamorgan. These two pictures were taken at Llancarfan in the churchyard.
