284 Non-Isolable Races. 
seedsmen's catalog-ties. Such statements relate, of course, 
only to practical and not to absolute constancy. It suf- 
fices that the harvests justify a reasonable hope that 
a certain number of variegated individuals will occur 
amongst the seedlings. Information as to the magni- 
tude of this proportion is rarely given. GODRON found 
Acer striatum variegatum to repeat the anomaly in only 
one-third of its seedlings. 1 VIVIAND-MOREL found only 
occasional variegated specimens amongst five hundred 
seedlings of Hedera Helix varicgata and only one 
amongst fifty of variegated Yucca, the majority being 
green. 2 PEPIN states that the seeds of Sophora japonic a 
foliis varlegatis always give rise to more variegated than 
green plants; 3 but in the case of these and similar data 
we know nothing, as a rule, as to whether the seeds have 
been derived from individuals which had been isolated. 
POLLOCK sowed the seeds of a variegated plant of Ballota 
nigra which he had found wild and obtained thirty per 
cent variegated seedlings. In the next generation the 
seeds of these, however, gave 60% of variegated indi- 
viduals. 4 The plant is now on the market and from the 
commercial seed I raised 25% variegated and 75% green 
plants. The seeds of a variegated specimen of Chrysan- 
themum inodorum found near Amsterdam produced 65 
plants in my garden, of which 5% were variegated whilst 
17 produced spotted leaves during the course of the 
summer, and the rest were green (1893). From the 
seeds of a variegated Lunaria biennis I raised green 
plants only, (1893) and I obtained the same result in
