Our somewhat obscure mystery seed from last week was from an Arizona grape ivy, Cissus trifoliata.

cissus-az-grape-ivy

It is called by other common names, such as cow-itch vine and sorrelvine. The name cow-itch comes from the fact that the leaves can cause skin irritation in some people.

cissus-Az-grape-ivy-2

Arizona grape ivy is a hardy vine that can tolerate the high summer temperatures. It is native throughout the southern United States.

cissus-3

The name "grape" ivy fits because it belongs to the same family as grapes, Vitaceae. The fruit are not edible, however.

Doesn't the seed look a little like a grape seed?
