Vitis cinerea canescens was first mentioned by Engelmann in 1868 under the name Vitis aestivalis, var. canescens. He does not describe it further than to say that it approaches Cordifolia. Bailey’s determination of its position was made from Engelmann’s herbarium specimens. He says: “A form with rounded or heart-like leaves, the upper half of the leaf lacking the triangular and 3-lobed shape of the type.” This variety has been found in Missouri, Illinois and Texas.
