Red Maple Variety ID

[flyingsquirrel25]

Well I know what a red maple looks like... But there has to be 10 or 15 different varieties that grow readily here in SE PA. I have a client (HOA), that has 5-6 red maples planted in a portion of open space but doesn't have the landscape plans for the area. They have tasked me with providing a quote for planting an additional 5-6 trees to fill in a space that the builders seemed to have just left blank. The kink... plant the same variety. When we looked at them they were a redish orange fall color (cant really go by that as we had a crap year). But they still had leaves after many other reds had already lost them. Does anyone have a resource for identifying different varieties? The interweb seams to be about useless as far as I can tell.
Thanks in advance for any help you may be able to provide!

Just sayin, know that you already know this, big mistake to plant more Red Maples. have to diversify.

This is a old book but has some good pics and identification pictures and info on just about everything. Should be able to find it at local library.

Thanks for you vote of confidence. I am well aware of the diversity question and problem. This development actually has a great street tree diversity when looking at it as a whole, pin oaks, willow oaks, red & sugar maples, zelcovas and even some green ash. It was like someone had a clue when they designed it... but as usual fell short with the idiots planting!!! And then of course the record keeping is atrocious.

Is it too old to have the newer (past 15-20 years) varieties of the red maple species? Looks like a really cool book, burlap cover?
