All specimens of recent finding so far as known to the writer have been obtained through 

 Mr. Henry Eggert, St. Louis, Mo., and Dr. Schreck, of Mt. Carmel, 111. Prof. L. H. Pammel 

 also secured it for me on the Mississippi above St. Louis. Mr. Eggert finds it along the Missis- 

 sippi River not far from St. Louis, though he reports that it occurs in Oklahoma, yet so 

 far, all the research of H. Jaeger and the writer failed to find any indications of it there or else- 

 where save along the Mississippi and Wabash Rivers. Doubtless, however, it is to be found on 

 most streams of Southern Illinois. It prefers argillaceous, alluvial, moist bottbm lands. Dr. J. 

 Reverchon (deceased in 1905), of Dallas, Texas, found it along the Sabine River in East Texas, 

 in 1903, and brought it to me for identification. His specimens were of the pure form and easily 

 identified. 



In growth, climbing, extremities of growing branches, thick diaphragm, long slender tendrils, 

 long clusters, with long peduncle, small berries without bloom, size and shape of seed, except 

 chalaza, long cordate leaf outline, except basal sinus, small stipules, late foliation, blooming and 

 ripening, smooth glossy leaves and wood, and flavor of fruit, — ^in fact the tout ensemble of the plant 

 clearly indicates the closer relationship with V. monticola and V. cordifolia and. not so close with 

 V. vulpina, as Professors Planchon and Viala had supposed. (Ampelideae, Planchon, Une Mission , 

 Viticole en Amerique, Viala, p. 88). It is, however, a very distinct and well characterized species, : 

 and can with no degree of propriety be included in one species with V. vulpina and V. cordifolia, 

 as Prof. C. S. Sargent suggested in Garden and Forest, January, 1890, p. 638. 



Though the basal sinus of leaves is obtuse as in V. vulpina and the chalaza generally 

 depressed, other characteristics, and especially the biological, I have named, must have more 

 weight. The species has been growing and fruiting with me for years near by V. vulpina, 

 V. monticola, and V. cordifolia, and certainly it is far nearer V. monticola and V. cordifolia than 

 V. vulpina and still less akin to V. rupestris than V. vulpina, hence I group it as shown in my 

 , classification. In habit of root-growth it is very much like V. cordifolia, and very unlike 

 V. vulpina and V. rupestris. . -'

Plant : Vine slender, tapering slowly, 'climbing 10 to 30 feet in its native regions ; exceedingly 

 unique in foliage, with an open, airy aspect. » 



Roots: Little branched, somewhat thickened and wrinkled, transversely, as in V. cord folia 

 and V. rubra, with a similar habit of division, also of firmness and penetration ; — quite distinct 

 from Precoces in these respects. 



Wood: When young distinctly angled, less than in V. Berlandieri, at first thinly hairy which 

 becomes floccose, the mature annual wood becoming cylindrical, finely striated, smooth, and of a 

 light reddish-brown color, at first, becoming a dark reddish-brown in winter, the outer bark often 

 splitting and, in fall and following season, separating freely in thin, fibrous strips ; wood rather 

 harder than in V. vulpina, but very brittle as are other parts of the plant; sectional view of mature 

 annual wood shows very distinct rays and pores between very open ; nodes very little enlarged, 

 nearly straight ; diaphragm plane, or nearly so, about 1/12' thick, or some thicker than in V. Longii. 

 Buds small, sub-globose, in young shoots, becoming conical at maturity; in unfolding small, 

 dull brownish-pink, half open, short, covered with pinkish tomentum. Tendrils intermittent, 

 usually once-forked, sometimes twice, moderately long, a little hairy or cottony like the young 

 wood, becoming smooth later, usually red when young, bright reddish-brown with maturity,
