CEPAGES. 143 



Whatever its real relations may be, the Taylor-Narbonne 

 has a resistance to calcareous soils comparable and even 

 superior to most Riparia X Rupestris. It may, therefore, 

 from this point of view, be used in reconstitution. Despetis, 

 who studied it during many years, thinks it has a high phyl- 

 loxeric resistance ; it is certainly superior to that of Solonis. 



Figure 73 shows very clearly the characters of the leaf of 

 Taylor-Narbonne, which are much more carved out than that 

 of Taylor. This cepage is vigorous, its cuttings root freely, 

 knit well with most European vines, and give fructiferous 

 grafts. If its resistance to phylloxera is proved, it will 

 ultimately be used in the same surroundings as Solonis was 

 formerly and also in poor sandy soils free from salt. 



Hybrids of V. Californica and V. Arizonica. These 

 hybrids are very numerous ; a scale of successive forms inter- 

 mediate between the two species has been found. They have 

 almost always been introduced into France under the name of 

 pure Californica or pure Arizonica, and have remained in col- 

 lections ; they are inferior in vigour to the Californica, and in 

 resistance to the Arizonica. They seem to require richer soil 

 than the latter, and are, therefore, of no interest. They suc- 

 cumb to chlorosis, like the Rupestris. 



Hybrids of V. Candicans and V. Berlandieri. 



On account of the co-existence of Candicans and Berlandieri 

 on the banks of the rivers and hills of Texas, on account 

 also of the almost continuous florescence of the latter, a great 

 number of hybrids have been produced in the wild state, 

 between these two species. Intermediate between these 

 two species are found, and almost in infinite number, many 

 forms of Berlandieri, with abundant woolly hair on the 

 young leaves and young shoots, considered thus far as pure ; 

 they are only hybrids of Candicans more or less defined. The 

 Berlandieri Planchon is an example of this. 



These hybrids are occasionally isolated on the chalky hills of 

 Texas, where they are generally found in rich and fresh soils ; 

 a certain number, especially those which have preserved to a 

 high degree the characters of the Berlandieri, are sometimes 

 found in dry and slightly fertile soils, but rarely in marl and 

 bluish-grey soils. And, what is more, the influence of the 

 Mustang has diminished the resistance to chlorosis of the 

 Berlandieri ; this explains why the hybrids experimented 

 with in the chalky soils of . Cognac have been rather
