than Cordifolia), and often hybridized with it. I have placed Cinerea 

 next Cordifolia, though otherwise it is a very distinct species. It ex- 

 tends from Western Texas to the Atlantic, from Illinois and New 

 York to the Gulf, even to Southern Florida, and in its pure form is quite 

 constant; leaves, from Manatee county, Fla., S. E. Arkansas, and Red 

 River, Texas, showing great similarity in having a long, taper point, 

 small, blunt teeth, under surface densely pubescent, of an ashy brown 

 color, and upper surface with scattering, cobwebby hairs drawn along 

 the surface. Young wood distinctly angled (more in western, less in 

 eastern samples), and, like the leaves, has the ashy pubescence ; young 

 wood under the pubescence brownish gray; tendrils long and strong; 

 clusters usually exceed Cordifolia in being longer and much more 

 branched ; fruit very sprightly, pure, rich, must on .Echsle's scale, from 

 100° to 120°, vinous, no trace of pungency or disagreeable property; 

 diaphragm thick to very thick; roots wiry, penetrating and resistant; 

 endures great heat and drought, but sensitive to cold. 



{h) Monticola (Mountain Grape). 



Hills of Central Western Texas, apparently an old, much multiplied hy- 

 brid of Cinerea with some round, smooth-leaved Riparia variety ; leaves 

 round, smooth, or with scattering, short pubescence; under surface of 

 a shining appearance, small, leathery, well suited to enduring heat 

 and drought, leaves out, blooms and ripens very late, about with Cin- 

 erea, and the cluster much resembles it, though smaller, and the ber- 

 ries larger. Varieties have been reported with white fruit and of fair 

 size and excellent quality. Young wood angled and pubescent, but 

 not so much so as Cinerea. Tendrils medium. 



4. yEsTivALiAN Group (Summer Grapes). 



Leaves out, blooms and ripens before Cordifolia, here in North Texas, but 

 in S. W. Missouri Mr. Jaeger reports it later in blooming, and after La- 

 brusca. With further investigation I find that the Cordifolia species blooms 

 before ^Estivalis here in Texas, as well as elsewhere, from three to five 

 days, also, that Warren, Herbemont, LeNoirand others of that strain, show 

 faint traces of Vinifera, though chiefly yEstivalis and Cinera. Diaphragms 

 thick, young wood dark, reddish brown, often with weak prickles, and 

 prunose bloom, especially near the joints on vigorous growth, which are 

 easily rubbed away; roots hard, penetrating, resistant; cuttings root 

 poorly ; tendrils medium to very strong.

 New York, Ohio, Indiana, IHinois to Missouri river, southward to 

 Maryland and Tennessee. Leaves thin, with a thin, light colored 

 pubescence along veins on under side, seldom lobed more than La- 

 brusca, fruit usually small and astringent, especially east, but larger 

 and finer going westward. A fine variety found by A. J. Caywood, in 

 New York, hybridized with Catawba (Labrusca) by him, gave that re-
