Vitis arizonica Engelm.

Plants sprawling to low climbing, shrubby, much branched. Branches: bark exfoliating in plates; nodal diaphragms 1.5–3 mm thick; branchlets slightly angled when young, becoming terete, arachnoid or arachnoid-floccose, sometimes glabrescent, growing tips not enveloped by unfolding leaves; tendrils along length of branchlets, soon deciduous if not attached to support, branched, tendrils (or inflorescences) at only 2 consecutive nodes; nodes not red-banded. Leaves: stipules 1.5–3 mm; petiole 1/2 to ± equaling blade; blade cordate to cordate-ovate, 5–12 cm, usually unlobed to 3-shouldered, sometimes shallowly 3-lobed, apex acute to acuminate, abaxial surface not glaucous, moderately to sparsely arachnoid, visible through hairs, veins and vein axils sometimes only hirtellous, adaxial surface sparsely arachnoid or glabrous. Inflorescences 4–12 cm. Flowers functionally unisexual. Berries black, slightly or not glaucous, globose, 6–10 mm diam., skin separating from pulp; lenticels absent. 2n = 38.

Streamsides and in canyons, often climbing into trees, 600-2260 metres in Arizona and Utah.

The fruit are eaten raw. They are also used for jelly. The leaves can be salted and soaked and then cooked and eaten.
