This is a curious variety of Oxford Ragwort distinguished by its sinuate-dentate oblong to oblong-lanceolate leaves. There are scattered records for this variety locally, on my patch in Woodlesford and Oulton (VC63) and in wider Leeds and Bradford where it has been recorded by Jesse Tregale and/or Mike Wilcox. Other than one other record in the BSBI Distribution Database from VC37 there are no other mapped records, although Sell & Murrell cite records for Cambridge, Didcot and Exmouth.
I have never been certain if it is a periodic chance mutation or a true variety, but I have known it in the same location in Oulton for at least 5 years. Over most of this period it seemed to persist as a single plant, but this year I found a few more at its main site and a new plant a kilometre away. Hardly vigorous, but I am more satisfied now that it is capable of regenerating itself from seed.
