Variegated Leaves. 269 
authors another fact is connected with this, viz., that 
varieties which have both variegated leaves and double 
flowers are much rarer than would have been expected 
from the prevalence of these two anomalies in horti- 
culture. 1 
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, Barbarea vulgaris, Chei- 
ranthus Chciri, Alyssum maritinium, Acer, Ilex, Aego- 
podiuin, Ligusticum, etc.). 2 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 3 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 
Barbarea vulgaris: whereas wild plants which occasion- 
ally present this character represent half races. Their

(Albicatio, Albinismus} and the published records of it are very 
scanty. The fine white-variegated Humulus japonicus variegatus 
would be well worth experimenting with.
