ae_. This statement
hardly admits of precise statistical proof; still, it is believed that
any observer who pays attention to the subject must come to the same
conclusion. This is but another illustration of the fact that conditions
which are abnormal in one plant constitute the natural arrangement in
others.

As to the suppressions that occur in the case of the sexual organs, and
the relations they bear to dimorphism, diclinism, &c., but little stress
has been laid on them in this place, because their chief interest is in
a physiological point of view, and is treated of in the writings of
Mohl, Sprengel, Darwin, Hildebrand, and others. All that need be said
here is, that teratology affords very numerous illustrations of those
intermediate conditions which are also found, under natural
circumstances, between the absolutely unisexual flowers, male or female,
and the structurally hermaphrodite ones. Rudimentary stamens or pistils
are of very common occurrence in monstrous flowers. See Chapter on
Heterogamy, &c.
