Abstract
If the broad-leaved deciduous trees and shrubs be contrasted with the evergreens, it is found that they are marked by a specific conductivity which in the free-growing and foliage-bearing shoots is far greater than in the class hitherto considered. This is well brought out by contrasting the results obtained on comparing an evergreen with a deciduous species of the same genus. The subjoined Table (I) for
Euonymus japonica
(evergreen) and
E
.
europœus
(deciduous) will serve to illustrate the point. It will presently become apparent, however, that there are certain exceptions to be reckoned with amongst the deciduous trees, especially in the case of young sapling trees and coppice stool-shoots (
e. g
. of ash or hazel).
