Identifying Vines

__________________________________________________________________________

Grape Family 

Vine I


FINALLY! The identification for this vine has been very difficult. It is not aggressive in my garden but it is persistent.

At first I thought it might be western poison-oak or fragrant sumac Rhus aromatica based on the leaf shape. The leaf is waxy and has a strong peppery scent reminiscent of roasted sesame oil. Thanks to a persistent “image search,”  I believe it to be Cissus trifoliata. I found it at, Sheryl Smith Rogers’  Window on a Texas Wildscape blog. She says,"Sorrelvine, cow-itch vine (Cissus trifoliate), is a member of the grape family. According to Wildflowers, Trees, and Shrubs of Texas, it can cause contact dermatitis in some individuals."
My botanical reference book does not include this vine under the scientific or common name.

Further research at the National Gardening Association revealed the, “The scent of the leaf is described as maloderous It appears to grow in Austin and San Antonio.  I have never experienced skin allergies from trimming the vine. Ladybird Johnson Wildflower Center also gave further verification.
