Identify this Vine?

Growing in the Qu'appelle valley in Saskachewan, this vine has berry clusters of 10 -12, the colour of Saskatoon berries, but with 5-6 large brown seeds in side. Leaves are similar to milkweed, but the berries are not?

 

Smilax lasioneura?

 

Definitely Smilax, and it seems S. lasioneura is the only one found in Saskatchewan.

 

Thanks a bunch, common name is "common carrion flower" which explains why we thought there was a dead animal at our lake lot!
