Vine not very vigorous, a slender grower, usually running on the ground or over low bushes. Canes slightly angular; internodes short; tendrils intermittent, simple. Leaves smaller and thinner than Rotundifolia and rather more circular in outline; not lobed; teeth rather open and spreading; petiolar sinus V-shaped; both surfaces smooth, rather light green. Cluster with more berries but about the same size as Rotundifolia. Berry one-third to one-half the diameter, with thinner and more tender skin; black, shining; pulp less solid, more acid and without muskiness. Seeds about one-half the size of Rotundifolia, similar in other respects. Leafing, flowering, and ripening fruit very late. In 1830 Rafinesque described, under the name _Vitis peltata_, or _Vitis floridana_, "a very singular species, lately found in Florida." This description is brief and includes many characters of no taxonomic value. In 1885 or 1886, Mr. J.H. Simpson of Manatee, Florida, sent a specimen of a grape growing in his locality to Munson which was taken to be Rafinesque's _Vitis peltata_. He consequently described it under the name _Vitis floridana_ but the species was not generally accepted. Later Simpson gave it the name _Vitis munsoniana_. Its habitat is central and southern Florida and the Florida Keys, and it is said to be the only grape growing on these Keys. It extends south of the habitat of Rotundifolia and blends into this species at their point of meeting. Munsoniana appears to be a variation of Rotundifolia, fitted to subtropical conditions. It is tender, not enduring a lower temperature than zero. In the matter of multiplication it differs from _Vitis rotundifolia_ in that it can be propagated readily from cuttings. Like Rotundifolia it is resistant to phylloxera. The species is of no value horticulturally. 3. =VITIS RUPESTRIS= Scheele.
