we have an apple tree in our garden, long neglected by us and our predecessors, which produces thousands (literally) of small yellow apples sometiems with a pink blush to part of one side. I have other photos of the fruit, leaf and tree - quite a distinctive striated greyish bark. They don't seem ornamental enough for crab apples. They are almost entirely 4 - 5cm in diameter, very round with no deep indentation at the non stalk end (sorry about the non technical term there!). I've tasted it and it is quite sharp, not really edible.
