THE CORDIFOLIA GRAPES 107 



or Winter Grape.) One of the most vigorous of American 

 vines, climbing to the tops of the tallest trees, and some- 

 times making a trunk 1 or 2 feet in diameter: internodes 

 long; the diaphragms thick and strong: petioles long; leaves 

 long-cordate, triangular-cordate with a rounded base, or 

 cordate ovate, undivided but sometimes very indistinctly 

 3-lobed or 3 -angled, the basal sinus rather deep and narrow 

 and normally acute, the margin with large angular acute 

 teeth of different sizes, and the point long and acute, the 

 upper surface glossy and the lower bright green and either 

 becoming perfectly glabrous or bearing some close and fine 

 inconspicuous grayish pubescence on the veins: stamens 

 erect in the sterile flowers and short reflexed- curved in the 

 fertile ones: clusters long and very many -flowered, most of 

 the pedicels branched or at least bearing a cluster of flow- 

 ers: berries numerous and small (about %-inch in diameter), 

 in a loose bunch, black and only very slightly glaucous, late 

 and persistent, with a thick skin and little pulp, becoming 

 edible after frost ; seeds medium and broad. In thickets 

 und along streams from Pennsylvania (and probably S. New 

 York) to E. Kansas and southwards to Florida and Texas. 

 It gives little promise to the experimenter. 



Far. fcetida, Engelm. , has fetidly aromatic berries, and grows 

 in the Mississippi Valley. 



Far. semper virens, Munson. A glossy-leaved form, holding its 

 foliage very late in the season : leaves sometimes suggesting 

 forms of F. palmata. S. Florida. 



Far. Helleri, Bailey. Leaves more circular (i. e., lacking the 

 long point), and the teeth round-obtuse and ending in a 

 short mucro. Kerr county, S. Texas, 1,600 to 2,000 feet. 



DD. Young shoots angled, and covered the first year with to- 

 mentum or wool. 



Vitis Baileyana, Munson. ('Possum Grape.) Less vigorous 

 climber than V. cordifolia, rather slender, with short inter- 

 nodes and very many short side shoots: petioles shorter and 

 often pubescent; leaves frequently smaller, the larger ones 

 shortly but distinctly 3-lobed (lobes mostly pointed and 

 much spreading), bright green but not shining above and
