Dichotomous Key

Does anyone know of a good dichotomous key to the eastern US roses? I'm aware of one or two websites with good species information, but wish I had a dichotomous key to be more certain of identification.

Lacking one, the most impressive identification source that I've found (for my area) is the book "Woody Plants of Maryland." But I have not found a stand-alone key yet.

Thanks for any ideas/sources.

Matt,
Erlanson (1934) gave a key, but it is not limited to eastern U.S. species:
