As you can see the flowers are borne several to a stalk like the cowslip but the individual flowers are much bigger than those of a cowslip and are almost the size of primrose flowers. However the flowers have a darker marking towards the centre which primroses do not have, and neither does the true oxlip.
These plants were growing on Clearwell Meend, fairly close to Clearwell caves, there were only about 4 individuals and they were growing underneath some fairly spikey Blackthorn bushes so I could not get a good angle to photograph them.
Another difference between the true Oxlip and the false Oxlip is that the individual flowers are all carried to one side of the main stem in the true oxlip, whereas in the false oxlip they form a random bunch pointing in all directions.
