Variegated Leaves. 269 



authors another fact is connected with this, viz., that 

 varieties which have both variegated leaves and d(juble 

 flowers are much rarer than would have been expected 

 from the prevalence of these two anomalies in horti- 

 culture.^ 



In variegated plants, as is well known, not only the 

 leaves are flecked. Their stems and calices are also often 

 variegated, and the same is true of the fruits (pears, 

 grapes, the siliquae of cabbage, Barharea vulgaris, CJiei- 

 ranthus Cheiri, Alyssnm maritimtim, Acer, Ilex, Aego- 

 podiiun, Ligusticum, etc. ).^ I have also sometimes found 

 galls on variegated oaks to be variegated, especially in 

 the case of the beautiful orbicular galls of Cynips Kollari. 



I shall now proceed to the important question of the 

 inheritance of this abnormality or the degree of fixing as 

 it is usually called. As already stated I shall exclude 

 from consideration the white-flecked''^ and the marginate 

 forms of variegation, and shall confine myself to the 

 ordinary cases of yellow variegated leaves. I shall give 

 the numerical proofs of my conclusions later, and shall 

 now proceed to deal with the question whether variegated 

 sorts are half races or intermediate races (see Chapter 

 II of this part). 



In my opinion the great majority of the variegated 

 garden varieties are intermediate races, as for instance 

 Barharea vidgaris; whereas wild plants which occasion- 

 ally present this character represent half races. Their

' I have not myself made any observations on this phenomenon 

 ( Albicatio, Albinismiis) and the published records of it arc very 

 scanty. The fine white-variegated Humuhts japonicns varicgafus 

 would be well worth experimenting with.
