[MAIPC] Angelica elata winter ID?

[Muth, Norris (MUTH)]

I know that distinguishing Aralia spinosa (native to North American east coast) from Aralia elata (invasive in Mid Atlantic region) can be somewhat challenging in the growing season. Is anyone aware of any traits that can be used in the winter? The prickles, buds, and leaf scars don't look obviously different to my very limited experience, but maybe someone else has observed something more closely?

(I'm also guessing A. elata tends to occur in denser stands, but that's not a very reassuring way to tell them apart).

Thanks!
