Cissus antarctica Ventenat, kangaroo vine, has been reported as escaped in California but probably is not naturalized there. Like C. verticillata, it has simple leaves, but it can be distinguished from that species by having rusty to brown, appressed (versus grayish white, erect) hairs on branchlets and leaves, prominent domatia in the abaxial secondary vein axils (versus no domatia), and dark blue (versus black) fruits.

1 Leaves simple, blade unlobed, surfaces usually hairy, sometimes glabrous.   1 Cissus verticillata
+ Leaves usually 3-foliolate, sometimes simple and blade 3-lobed, rarely unlobed, surfaces glabrous.   2 Cissus trifoliata
