...well, I think so! A brief stop today to look at some semi-interesting flora growing on a few spoil tumps in the middle of an abandoned building plot revealed a good quantity of a richly fertile Cephaloziella. With angular gemmae, edentate lobed perianth bracts that are connate, I'm pretty confident this must be integerrima, a potential first for Wales. If confirmed I'll need to determine how extensive the population is. I have a feeling building works were stopped ~6 years ago, as the developer did not have planning permission. This is a highly vulnerable population, but best we get the id confirmed first before looking at safeguarding the species at this site. There is no referee listed for this genus in the latest FB, so Sam, I wonder if you can suggest someone who would be willing to examine a voucher, yourself perhaps? [I called in very briefly again the following day and noted integerrima to be present on a few additional tumps, the mounds being the ground excavated for a series of post holes about 10 years ago!].
