Cordifolia makes a good stock for grafting, being vigorous and forming a good union with most of our cultivated grapes. It is seldom used for this purpose, however, on account of the difficulty of propagating it by means of cuttings. For the same reason vines of it are seldom found in cultivation. It is probably of no importance horticulturally. =VITIS CORDIFOLIA FOETIDA= Engelm. =1.= Engelmann, _Am. Nat._, =2=:321. 1868. V. CORDIFOLIA, var. FOETIDA. =2.= Ib., _Mo. Ent. Rpt._, =1872=:60. =3.= Bailey, _Gray's Syn. Fl._, =1=:424. 1897. V. CORDIFOLIA, var. FOETIDA. Apparently the first record of _Vitis cordifolia foetida_ is Engelmann's mention of it in the _American Naturalist_ of 1868. In 1872 he speaks as though this is the common Mississippi Valley form, for he says: "In this valley at least the fruit has a strongly and even fetidly-aromatic taste". The variety apparently is similar to the typical Cordifolia in every respect excepting the aromatic fruit. =VITIS CORDIFOLIA SEMPERVIRENS= Munson. =1.= Munson, _Rev. Vit._, =5=:165. f. 53. (cited by =2=). =2.= Bailey, _Gray's Syn. Fl._, =1=:424. 1897. V. CORDIFOLIA, var. SEMPERVIRENS. =3.= Viala and Ravaz, _Am. Vines_, =1903=:78. _fig. of leaf._ _Vitis cordifolia sempervirens_ is a south-Florida form of Cordifolia named and first described by Munson in the _Revue Viticole_. It differs from typical Cordifolia in having leaves which are thicker, narrower, more oblong, with a long lanceolate point, completely glabrous and more or less glossy on both surfaces. These leaves remain on the vines very late in the season. This variety is said to be very resistant to an excess of lime in the soil. =VITIS CORDIFOLIA HELLERI= Bailey. =1.= Bailey, _Gray's Syn. Fl._, =1=:424. 1897. V. CORDIFOLIA, var. HELLERI. =2.= Viala and Ravaz, _Am. Vines_, =1903=:79. V. CORDIFOLIA VAR. _Vitis cordifolia helleri_ is first mentioned by Bailey in 1897. It differs from the ordinary forms of Cordifolia in having more circular leaves without the lanceolate point. Viala and Ravaz state that such forms are found in clay soils. Bailey refers to it as an upland south-Texas form found at altitudes of from 1600 to 2000 feet. 11. =VITIS BAILEYANA= Munson. =1.= Munson, _U. S. D. A. Pom. Bul._, =3=:14. 1890. V.
