Smilax glauca
Smilax glauca, the cat greenbriar or catbriar is a woody vine in the family Smilacaceae. It is native to central and eastern portions of the United States, where it is a common and conspicuous part of the forest vegetation. It is also common across much of Mexico. "Smilax glauca" has prickly stems and climbs by means of tendrils. Leaves are notably gray-glaucous to whitish beneath. It commonly inhabits wooded areas and fences and is often found growing with other species of "Smilax". The plants tend to be evergreen in the more southern United States. Description.
