Sanguinolenta x Quinquangularis [Martins Magic]

My flower bud on the new hybrid xerogona is forming, looks like it may be a pink flower.
I have other seedlings of this cross which look different, so this is seedling 1.

 Below a picture of the flower, better photo to follow.

Martins Magic has survived well and there are now about 15 plants, hopefully some will be availible later this year.
