There is a single tree in the lower Don River (Toronto) that has yellow cherry sized fruit on it. The inside flesh is apple like. I don't think it is a crab apple and I am exhausted by trying to find it on the net. (Attached pic is the fruit and leaves scanned......the fruit is actually yellow.) I spend alot of time trying to indentify plants and butterflies but often come up empty handed. Is there a great book which references all that can be found along side the Don River? Thanks
Definitely looks like something in the rose family, along the lines of Pyrus / Malus / Crataegus ... I don't know of any books specifically about the Don River area. Local library would be the place to go for that - while there, look up the excellent Shrubs of Ontario book (which your library really ought to have), as I suspect this plant will be in it.
Dreamcatcher, It sure looks like a crabapple. Forgive me if I'm assuming too much but some crabs do have yellow (and orange) fruit. Regards, Ernie
Crabapple (Malus), same genus as orchard apple. That's why you have seen a resemblance. Hundreds of kinds of crabapples being grown in North America, there are also native wild species - although this example would not be one of those.
