We thus reach the conclusion as to, 



The Specific Basis of American Viticulture 



Rupestris, Longii. Vulpina, Monticola. Berlandieri Bourquiniana. Vinifera. Lincecumii. 

 Bicolor. ^Estivalis Simpsoni. Candicans. Doaniana. Champini, Labrusca. Rotundifolia. Munson- 

 iana, seventeen in all? 



These with proper application as to climate and soil can well supply all parts, from Puget's 

 Sound and Dakota to Puerto Rico. 



All the other species can be neglected without loss 



An abridgment of the above, which would still supply nearly every requirement, and be 

 the best possible list for the number of species included, would be Rupestris. Vulpina. Berland- 

 ieri, Bourquiniana, Vinifera, Lincecumii. Simpsoni, Doaniana, Champini, Labrusca, Rotundi- 

 folia. But for any limited region a half dozen species will be abundant, and few hybridizers 

 will be found using that many. Most breeders so far have used only two to four. 



Partial List of Varieties of Grapes that have been, or are Growing in the 



Munson Experiment Grounds 



For Study, Testing, Improvement and Market Purposes, not Including Varieties Originated by 



the Writer 



Explanation 



After each species and variety are placed some characters and figures; for example, V. ru- 

 pestris f, ^F^TT This (t ) means that the vine or vines have staminate flowers. This ( f ) that 

 the vine or vines have flowers with pistils and reflexed stamens and can bear fruit if the flowers 

 are pollenized by vines having erect stamens, but cannot fertilize themselves. In other words, 

 (f ) means male vine or vines and ( , ) means female vine or vines ( ' ) means, hermaphrodite 

 or perfect flowers with erect stamens. The figures tell the date at which the species or variety 

 blooms at Denison. Texas.* The upper figure is for the month, the lower for the day of month. 

 The above figures mean April 20th to 30th. b. means black, r. red, and w. white: thus. Concord 

 * ^-f ^ b. means that Concord has perfect flower, erect stamens, blooms May 5th to 10th, at Denison, 

 and is black. 



This will be found a very convenient and useful table both for the experimenter and practical 

 vineyardist, as varieties with reflexed stamens must have vines with erect stamens, flowering at 

 same time near by to bear well. 



List 



Species. Individual Vines or Varieties. 



V. rupestris, f , ^ 4 - 5T j, about 125 vines, from Texas and Missouri, including Mr. Jaeger's best kinds.

 V. Girdiana, f , ^-f 5, a dozen vines from Southern California and Mexico. 

 V. Calif ornica, j , y?rW many vines from Napa, Sacramento, and Feather River, Cal., and 

 Rogue River, Oregon. 



* As the dates of flowering given here were observed in different and more irregular seasons than those 

 given in Table, Guide to Selecting Varieties of Grapes for Various Regions, Soils and Purposes, Chapter III., 

 pp. 212-213, it is better to consult and follow that table for relative flowering times of varieties.
