I think you are confusing the "loquat" with the "medlar". The loquat is still relatively common, doesn't have a gaping open end, is yellow to orange, and can be eaten out of hand. The medlar is darker in color, has a very open calyx, and is practically inedible direct from the tree. The names are sometimes confused, with the loquat sometimes called a "Japanese medlar". Anyway, did yours possibly match this one instead: http://italywithgusto.com/praise-to-the-italian-loquat-fruit...?
