CEPAGES. 91 



stiffness; petiolar sinus (Fig. 41) deep open V shape. Tufts 

 of down disseminated on the canes and petioles; whitish 

 buds. Young roots red. This Rupestris is probably a hybrid 

 of Rupestris and Mustang. The tomentum which covers the 

 buds, the numerous tufts of down disseminated on the 

 canes, the colour and texture of the leaves, gives a resem- 

 blance to certain forms of Champin. The Rupestris Metal- 

 lica is very vigorous, and grows well on the dry hills of the 

 environs of Montpellier." 



Rupestris with violet shoots. Stump of less vigour than 

 those of the preceding forms and less meritorious, defoliation 

 precocious, habit bushy. Canes large, hazel colour, with 

 darker lines at their point of insertion; young shoots violet. 

 Leaves large, a little longer than wide, slightly thin; petiolar 

 sinus open, with straight sides; indentations rather long and 

 acute, in two series; rather dark green on upper-face. 

 Petiole, with very pronounced groove, violet-coloured. 



Rupestris Ecole. This very vigorous form, with large 

 trunk, has existed in the collections of the School of Agricul- 

 ture, Montpellier, since 1879; but it is very inferior to 

 Rupestris Martin, and like it, very easily affected by cal- 

 careous soils. Stump and trunk very large, canes trailing, 

 slightly bushy; canes vinous rose, slight bloom, bent at the 

 nodes, internodes short. Leaves glabrous, sub-rectangular, 

 thick, folded along the mid-rib, widely open, margin a 

 little folded inwards, crepe-like structure between the ribs, 

 glaucous green, slightly shining on the upper-face, lighter 

 green and shining under-face; ribs strong, green, thickened 

 at the level of the petiole; petiolar sinus very open U shape; 

 one series of large teeth, little marked. Petiole long and 

 strong, with large flat groove, colour dull vinous-red, similar 

 at the origin of the ribs on the upper-face. 



Rupestris of Fortworth. -- This form, according to Mil- 

 lardet, was sent, in 1882, by Hermann Jaeger of Neosho, to 

 de Grasset. It comes from Fortworth, in Texas. The 

 Rupestris de Fortworth, as it exists in commerce, represents 

 a group in forms, rather than a typical form; they are in- 

 ferior to the Rupestris du Lot, but are not without value on 

 account of their great vigour. Herewith are the characters 

 of one of the most vigorous forms : 



Stump very vigorous, trunk strong; young shoots rosy ; 

 canes rather large, bluish, clear hazel colour, slight bloom. 

 Leaves (Fig. 42) very large thick, light glaucous green,
