Crataegus x rubrinervis

I popped over to Skelton Lake (VC64) today to check up on the bush of Crataegus x rubrinervis (Common Hawthorn C. monogyna x Five-seeded Hawthorn C. pentagyna) I first found in 2018. There are a couple of bushes of Five-seeded Hawthorn a few hundred metres away, and this bush looks like it has arisen in situ.

It has the foliage, large succulent fruit (at their largest they are blackcurrant sized) and suberect sepals (recurving at the tips) of Five-seeded Hawthorn, but with fruit dark red to red-purple rather than purple-black and seeming to ripen later as well. The flesh is reddish coloured, and in this case most of the fruits checked had two pyrenes, but a few had three.
