Mystery....Euphorbia?

My students and I encountered this plant at the Museum of the American Indian last week.  Damn, if I'm not stumped on what it is.  Any ideas?


At first glance, I thought it may be an Aslcepias, primarily because it looked like milkweed bugs were on the stem. But after reviewing this old post, I'm pretty sure they aren't milkweed bugs and certain this isn't an Asclepias (though the stem, when broken, did emit a milky glaze). 


The overall habit reminds me of an Euphobia, though I can't confirm a particular species.  The jointed stems also have me a bit stumped. Whataever it is, I love the variable fall color, with orangey green hues along the center, turning deep burgundy at the leaves' edges.
