Narrative

Type = species. Per Hedrick (see citation): "[about V. munsonia] 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. [...] 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. Munsonia appears to be a variation of Rotundifolia, fitted to sub-tropical 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 propigated readily from cuttings. Like Rotundifolia it is resistant to phylloxera. The species is of no value horticulturally."
