Can you please tell me the name of this tree growing in full sun in Chicago? It's about 10-feet tall, has dark green leaves, and berries.
Thanks!

RE: Please ID this tree

I'm wondering if this is a Crataegus sp. which I do not know. I am basing this on the fruit and the appearance of the suckers at the base which could come form the rootstock and which appear to show a more typical Crataegus leaf shape. Another possibility is a Sorbus sp. Anyway definitely Rosaceae.

Outlines of shoots visible in top picture are like those of hawthorn. Second picture not opening all the way for me, other(s) not at all.

All the sorbus that I am familiar with have clusters of fruit and compound leaves. Could well be a crataegus, but if so, it should have thorns, and the fruit is usually a pome (like an apple or pear), not a berry - for what it's worth, this fruit looks like a pome to me. If the fruit is a pome then it will have seeds in many separate chambers. However, Crataegus monogyna has a single seed. Most dark-leaved trees in the rose family are cherry cultivars, which prolifically produce green-leaved suckers, but this tree lacks glands on the petioles. I've attached a Crataegus key.

It looks like Crataegus crusgalli var. inermis (Thornless cockspur), although I almost didn't recognize it because around here they are usually terribly disfigured by leaf miner and rust.

I think you've got it buckeye15. Sadly this one has been lollipopped so we don't see the true form.

bejoy2, I was considering the possibility that the fruit was the survivor of a cluster and not all Sorbus have pinnate leaves. Check out S aria at the link. They are beautiful small trees, native and widely planted in the UK. The cultivar 'Lutescens' particularly is so silvery in spring that it looks like blossom rather than foliage. Nor do all Crataegus have thorns, buckeye15's suggestion being one of the thornless ones.
