BUSHBERG CATALOGUE. 



tivated forms are very similar; figs. 1 and 2 are 

 from berries with 1 and 2 seeds, fig. 3 from a 

 larger 4-seeded berry. 



Figs. 4 to 7. Vitis Riparia from wild plants ; 

 figs. 4 and 5 from Goat Island on the Niagara 

 Falls: fig. 4 a single broad seed; fig. 5 from a 

 3-seeded berry; fig. 6 from a 2-seeded berry 

 from the shores of Lake Champlain, in Ver- 

 mont ; fig. 7, seed of the June grape from the 

 banks of the Mississippi below St. Louis. The 

 seeds are obtuse, or very slightly depressed on 

 top, chalaza rather flat, elongated and gradu- 

 ally lost in a groove which encloses the scarcely 

 prominent laphe. The seeds of the true Vitis 

 Cordifolia are similar, but usually with a more 

 prominent raphe, somewhat intermediate be- 

 tween ^Estivalis and Riparia. 



Figs. 8 and 9. Taylor-Bullit and Clinton, 

 both believed to be cultivated forms of Ripa- 

 ria, with seeds larger, but of the same shape. 



Fig. 10. Delaware, with broad, notched 

 seeds, indistinct raphe and rather flat chalaza 

 appears intermediate between Riparia and La- 

 brusca. 



Figs. 11 and 12. Vitis Labrusca. Fig. 11 a 

 native of the District of Columbia and fig. 12 of 

 the mountains of East Tennessee. Seeds large, 

 notched; chalaza more depressed in the first 

 than in the second; no raphe is seen in the 

 groove which extends from the chalaza to the 

 notch. 



Fig. 13. Vitis Candicans, from Texas, simi- 

 lar to the last, seeds broader, with shorter 

 beak, less distinctly notched, no raphe visible. 



Fig. 14. Vitis Vulpina, from South Carolina, 

 a very distinct seed, flatter, with straighter 

 sides, short beak, wrinkled on both surfaces, 

 notched on top, narrow chalaza, no visible raphe. 



Figs. 15 to 18. Vitis Vinifera, from Europe, 

 different forms, which are introduced here for 

 comparison with the American species. Fig. 

 1, Brusca, the. native species of Tuscany 

 (Northern Italy) ; fig. 16, Riesling, cultivated 

 on the banks of the Rhine; fig. 17, Gutedel 

 (Chasselas), from the same region; fig. 18, 

 Black Hamburg, from a grapery near London. 

 All these seeds, different as they are among 

 themselves, are easily distinguished from all 

 American grape-seeds, by the narrower and 

 usually longer beak (or lower part), and espec- 

 ially by the large, though not very prominent 

 chalaza, which occupies the upper, and not the 

 middle part of the seed. These four specimen 

 seeds represent the principal forms, but not all 

 European grape seeds agree entirely with them.
