84 AMERICAN VINES. 



numerous and upright on the principal canes; leaves of 

 medium dimensions in soils of ordinary fertility, lustrous 

 on both faces, the shoots rather reddish in the herbaceous 

 state. Amongst these Rupestris, we mention among the 

 most vigorous forms, Rupesttis Mission, Rupestris du Lot; 

 then a second group: Rupestris Ganzin, Rupestris Martin, 

 etc., all very vigorous and meritorious. 



The second principal group is formed of all the Rupestris 

 with large leaves, much larger than those of the preceding 

 forms when grown in similar soil, of bushy habit, with 

 numerous ramifications; leaves folded along the mid-rib, a 

 little more open and less imbricated on the branches. Most 

 of these Rupestris are very vigorous, and have large canes. 

 We subdivide this group into: 



ist. Rupestris with Jarge thick leaves, very dark-green 

 on the upper-face, slightly honeycomb structure, open. 

 Ex.: Rupestris a feuilles metalliques or R. Metallica, 

 Rupestris a pousses viollacees, etc. 



2nd. Rupestris with large leaves, fleshy and very shining, 

 open and sometimes thrown back at the edge, often very 

 goffered in structure between the principal and secondary ribs. 

 Ex. : Rupestris Ecole, Rupestris de Fortworth, etc. 



3rd. Rupestris with very large leaves, plain, nearly as 

 wide as long, non-bushy habit. These Rupestris have 

 certainly been subject to hybridization with other species, 

 although we mention them as pure Rupestris. Ex. : 

 Rupestris Kansas, Rupestris No. 62 of Jceger, etc. 



Mazade has published a monograph of great value in the 

 Revue de Viticulture, dealing only with meritorious forms of 

 Rupestris, from this monograph most of the following infor- 

 mation is taken, the forms being classed in three groups: 

 i st. Rupestris of bushy habit, leaves with slightly 

 undulating margins, regularly folded along 

 the mid-rib; usually small. General appear- 

 ance yellowish. Ex.: Rupestris Ganzin. 

 2nd. Rupestris of erect habit, principal ramifications 

 only trailing on the ground; leaves slightly 

 folded along the mid-rib; petiolar sinus 

 bracket shape. Ex.: Rupestris du Lot. 

 3rd. Rupestris of trailing habit, leaves with dark 

 metallic sheen. Ex. . Rupestris Mission, 

 Rupestris Martin, Rupestris Metallica, Rupes- 

 ris de Fortworth.
