gated in late autumn and winter but becomes completely 
green in summer. 1 
In all these observations there was no question of bud- 
variation. 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;--! 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. Aesculus 
Hippocastamun is the best known example, so also are 
Evonymus japonicus, Pelargonium zonale, Azalea ja- 
ponica, Aucitba japonica, Ilex Aquifolium; also Spiraea 
eallosa, Kerria japonica, Vlnca major, 2 Hydrangea Jwr- 
tensis, 3 Fagus syh'atica, 4 Ulmus campestrisf Cornus son- 
guinea , r ^ Sambuciis nigra? Myrtus communis tarantina, 
Zea Mays etc. 
The inheritance of variegation through seeds is one 
of the most interesting phenomena presented by this

named varieties.
