CHAP. 47.—TREES WHICH ARE UNPRODUCTIVE IN CERTAIN PLACES.
Certain trees also become unproductive, owing to some fault
in the locality, such, for instance, as a coppice-wood in the
island of Paros, which produces nothing at all: in the Isle of
Rhodes, too, the peach-trees [Note] never do anything more than
blossom. This distinction may arise also from the sex; and
when such is the case, it is the male [Note] tree that never produces.
Some authors, however, making a transposition, assert that it
is the male trees only that are prolific. Barrenness may also
arise from a tree being too thickly covered with leaves.
