This form of Candicans was named and described by Shuttleworth in a manuscript now in the Herbarium Boissier at Geneva, Switzerland. Botanists seem divided as whether to regard it as a separate species or as a botanical variety. Its habitat is central and southern Florida. Coriacea is more tender than the regular forms of _Vitis candicans_ and this alone would make it worthless to the northern cultivator even were it otherwise valuable. 22. =VITIS SIMPSONI= Munson. =1.= Munson, _Soc.

Vine very vigorous, climbing; shoots cylindrical with much brownish pubescence; diaphragms very thick; tendrils intermittent. Leaves with stipules short and broad; leaf-blade rather thin, large, broadly cordate, usually considerably lobed; petiolar sinus of medium width and depth; margin coarsely toothed; upper surface slightly rugose and of a dark-green; lower surface with rusty white pubescence sometimes becoming almost a blue green; the shape of leaf and amount of pubescence vary widely. Clusters large, loose; peduncle long; pedicel thick. Berries small to medium, more tender in pulp and less astringent than _Vitis aestivalis_, black with moderate amount of bloom. Leafing, blooming, and ripening fruit late. _Vitis simpsoni_ was named and briefly described by Munson in 1887. In 1891 he stated that the species is a hybrid of _Vitis coriacea_ (here considered a variety of _Vitis candicans_) crossed with _Vitis cinerea_. Bailey states that it is probably a hybrid of Aestivalis crossed with Coriacea. Some forms of Simpsoni are said to be very difficult to distinguish from _Vitis labrusca_. Simpsoni prefers warm, sandy soils and is found in central and southern Florida. It roots from cuttings with great difficulty; it is tender and will not withstand cold winters. While it is very resistant to phylloxera and also to mildew and black-rot, its leaves are said to be much attacked by leaf-rollers. The blossoming period is just after Aestivalis. The berries are of good flavor and might be of some value for the country along the Gulf Coast but it is of no value for the North. 23. =VITIS LABRUSCA=[150] Linn.[151]
