Variegated Leaves. 281 



gated in late autumn and winter but becomes completely 

 green in summer.-^ 



In all these observations there was no question of bud- 

 \'ariation. Of the causes of this phenomenon little is 

 known. On the other hand it is generally recognized that 

 if resting buds on variegated plants are allowed to grow 

 vigorously they often develop into completely white or 

 yellow so-called chlorotic branches; — I mean those buds 

 which on green sorts would develop into strong succu- 

 lent shoots under similar inducements, but the chlorosis 

 soon puts an end to this development. Adventitious buds 

 which arise from the stem a little above the soil fre- 

 quently give rise to chlorotic branches, either after the 

 stems have been cut down or when the leaves have been 

 eaten by snails, or from some other cause. Aescidus 

 Hippocastanum is the best known example, so also are 

 Evonyinus japoniciis, Pelargonium zonale, Azalea ja- 

 ponica, Aiicuba japonica, Ilex Aquifoliuin ; also Spiraea 

 callosa, Kerria japonica, Vinca major,^ Hydrangea lior- 

 tensis,^ Fagiis sylvatica,'^ Uliniis caiupesfris/^ Cormis san- 

 guiueaS' Saiiibuciis nigra,^ Myrtns communis tarantina,'^ 

 Zea Mays etc. 



The inheritance of variegation through seeds is one 

 of the most interesting phenomena presented by this
