chlorosis. For dry or rich siliceous soils they would be 

 inferior to other graft-bearers on account of their small 

 vigour. 



Hybrids of V. XEstivalis and V. Cinerea. The wild 

 forms are rare. Millardet and de Grasset isolated one of them 

 in 1882, and Munson found one in Georgia. These vines are 

 generally of little vigour; their value of resistance and adap- 

 tation is not known, but we may assume that they are not 

 meritorious. 



Hybrids of V. /Estivalis and V. Rupestris. Exist in 

 a wild state in the south of Missouri and Indian Territory. 

 They generally have a strong trunk and great vigour, but 

 only grow in dry siliceous soils, the soils for Rupestris. The 

 forms tried in France, amongst others, the Rupestris Taylor 

 and Rupestris de Lezignan, grow vigorously in Rupestris 

 soils, and in good garrigues soils of the south of France; in 

 calcareous and chalky marly soils they become stunted after 

 the first year's planting out. They are not suitable varieties 

 for chalky soils, but they make -very good graft-bearers, and 

 are vigorous in all soils where the Rupestris could be culti- 

 vated, especially in pebbly-siliceous, poor and compact soils. 

 Millardet and de Grasset have selected a few Rupestris and 

 Estivalis, which become yellow in cretaceous chalks like the 

 wild forms. 



Rupestris Taylor. Form isolated at Mas de las Sorres; 

 not much affected by phylloxera. Stump very vigorous, 

 trunk strong, habit exclusively spreading. Canes sinuous, 

 strong, deep-chestnut colour, nodes covered with vinous- 

 coloured bloom. Leaves large, wider than long, orbicular, 

 thick, fleshy, goffered structure, deep green, slightly shining 

 on the upper-face, light glaucous green and dull on the 

 under-face; ribs strong, covered with stiff hair; petiolar 

 sinus deep, lyre-shaped. Seeds same character as V. Esti- 

 valis. Resistance, 16. 



We will also mention the Rupestris de Lezignan, which is 

 a very vigorous hybrid of Rupestris and Estivalis. Accord- 

 ing to Millardet, this hybrid selected by Marron-Martin and 

 Joulia, of Lezignan, is distinguishable from Rupestris Taylor 

 by the character of its wood" That of Rupestris Lezignan 

 is round, while that of Rupestris Taylor is flat, and has very 

 marked flutings between the nodes."
