link between I", cordifolia and I', cincrca, with still other characteristics found in neither of those 

 species, but leaning mostly toward V . cincrca. In October, 1889, I found a number of vines of 

 this species along the borders of the Kanawha River in the vicinity of Kanawha Falls, W. Va., 

 and the same year received wood from Mr. J. K. Hoyt, of Duncombe Co., North Carolina, as the 

 "Wild 'Possum Grape," which was grafted and grew, proving to be the same species. In Sep- 

 tember, 1890, Mr. Hoyt sent me ripe fruit from other vines of the " 'Possum Grape" found wild 

 in his vicinity, all being of this species. All plants of the species so far known to me grow along 

 mountain streams at an altitude of 1500 to 3000 feet. 



Some of the vines seen at Kanawha Falls, had Phylloxera galls upon their leaves, but the 

 vines were in good health. The formation there is carboniferous limestone, the soil a calcareous 

 clay. The only other species of grapes observed at that point were V. cordifolia and V. ccstiralis. 

 From Roanoke Co., Va., I have received in addition to this species, specimens of }'. v//Yu/;v, 

 V. labrusca, V. cordifolia and V. rotundifolia. From Buncombe Co., N. C., I have received 

 besides V. Baileyana, V. aestivalis, V. labrusca and V. cordifolia, V. rotundifolia, reported as not 

 found native there, the altitude, 2000 to 3000 feet, being above its range. I have not yet found 

 or obtained any hybrid forms of this species. After having given the species the name of \~ir- 

 giniana, it was noticed that V r . Virginiana is a synonym for V. vulpina and other species, hence 

 I conform to the rule, that a name "once a synonym, always a synonym," and rename my 

 species, dedicating it to my friend Dr. L. H. Bailey.

"Winter Grape," "Frost Grape," "Sour Winter Grape," in Texas; "Fox Grape" in Illinois, 

 ' 'Possum Grape" in Virginia, North Carolinia and South Carolinia, not distinguishing it from 

 T . Baileyana. 



Plant: Vines acquire great size, climbing to the tops of the tallest trees, covering them with 

 an open canopy of dark green glossy leaves, with pendent branches gracefully extending there- 

 from, from which the naked, rapidly growing tips of the young branches project. 



Roots. In one year seedlings, enlarging downward for a foot or more from the collar, forking, 

 non-axial, firm, fully resistant, and penetrates quite successfully very limy as well as sandy soils. 



Wood: Young wood cylindrical or oval, angled slightly when quite young, of a pale yellowish- 

 green, in most of a, or bronze-red, always in b, and partly so in a; the surface about, or on the 

 nodes in immature wood and at the bases of the young branches, covered with short fawn-colored 

 pubescence, especially in the bronzy form; upon mature wood, outer bark but slightly adhering, 

 separating in broad, nearly regular checked plates which can be easily separated when the wood 

 is but one year old, of a drab or hazel color, with darker and lighter markings, making it in 

 nearly every instance appear mottled, deeply striated; surface smooth, except in some plants 

 a rasp-like feeling when the ringer is passed over it; without any or rarely a trace of prunose 

 bloom near the nodes; annual wood rather soft and tough; sectional view open, rays wide apart, 

 pores large; nodes little enlarged, slightly bent, often pubescent; diaphragm thick, 1/8' to 1/5' 

 or more, biconcave; buds medium, sub-conical, sub-acute, terminated with rusty wool, at their 

 opening in the spring of a grayish-purple, or violet, or rusty pink or bronze in the more pubescent 

 form, gradually becoming green with rapid expansion of leaves, tip closed, tendrils usually once 

 forked, rarely twice, intermittent, finely striated, smooth: internodcs long to very long. 3' to 1'
