 Vines, 1903:154. 



Vine vigorous, climbing or shrubby if left without support ; wood on mature canes 

 cylindrical or slightly angled; diaphragm thin; tendrils intermittent, bifid, rather weak. 

 Leaves medium in size, broadly cordate, notched or lobed and with a triangular apex; 

 petiolar sinus medium in depth, usually narrow; margins with rather large, notched- 

 like teeth; upper surface of a peculiar bluish-green, frequently somewhat rugose with 

 more or less tomentum; lower surface usually with a dense whitish pubescence which 

 shows also on shoots. Cluster medium to small. Berries variable in size, average 

 medium, black with a thick bloom. Seeds somewhat resembling Labrusca but with 

 shorter beak and more distinct chalaza; has characteristic groove extending from 

 chalaza to beak. 



Doaniana is quite variable, some specimens being nearly glabrous 

 at maturity while others are densely covered with white pubescence. Mun- 

 son has separated the species into two forms which he calls the early Doani- 

 ana and the late Doaniana. The species was described and named by 

 Munson in 1890. 



It is found chiefly in northwest Texas but it ranges from Oklahoma 

 to Vjeyond the Pecos River in New Mexico. It is considered by Bailey and 

 Viala to be a probable hj-brid with Vitis candicans as one of the parents. 

 Doaniana is exceedingly hardy, withstanding great cold as well as great 

 heat. It apparently prefers rather light soils as it is indigenous to sand- 

 banks along rivers and the beds of sandy ravines. 



Munson states that in cultivation it does well in any but very limy 

 soils. The fruit is of comparatively good quality but the skin possesses 

 some of the pungency of Candicans. The berries are quite persistent, 

 hanging to the pedicel some time after ripe. The vines are not pro- 

 ductive. The character ot the must is apparently unknown. The roots 

 are hard, penetrate deeply into the soil, and are resistant to phylloxera 

 though somewhat variable in this respect. Doaniana grows readil}- from
