e of the inflorescence, and their
pedicels were much longer than usual.

Linne, as has been already stated, considered these flowers to be
sterile, and only capable of multiplication by division of the root, but
Willdenow obtained seeds from the _Linaria_ which reproduced the
anomaly when sown in rich soil. Baron Melicoq obtained similar
results.[239] Mr. Darwin[240] raised sixteen seedling plants of a
peloric _Antirrhinum_, artificially fertilised by its own pollen, all of
which were as perfectly peloric as the parent plant. On the other hand,
the same observer alludes to the tendency that these peloric plants have
to revert to the usual form, as shown by the fact that when the peloric
flowers were crossed with pollen from flowers of the ordinary shape, and
_vice versa_, not one of the seedlings, in either case, bore peloric
flowers. Hence, says Mr. Darwin, there is in these flowers "a strong
latent tendency to become peloric, and there is also a still greater
tendency in all peloric plants to reacquire their normal irregular
structure." So that there are two opposed latent tendencies in the same
plant. A similar remark has been made with reference to malformations in
general by other observers.

It would be very interesting if some competent naturalist would collect
information as to whether any variations in degree of fertility exist in
the three forms of flowers in _Linaria_, viz. the ordinary one-spurred
form, which is intermediate between the spur-less and the five-spurred
form. It must be remembered, however, that in the latter cases the
stamens are often deficient. In the _Compositae_, where there are regular
flowers in the disc and irregular ones in the ray, sexual differences,
as is well known, accompany the diversities in form.

To Mr. Darwin the author is indebted for the communication of some
flowers of _Corydalis tuberosa_ (figs. 124, 125), provided with two
spurs of nearly equal size. To these flowers allusion is made in the
work already quoted[241] in the following terms:--"_Corydalis tuberosa_
properly has one of its two nectaries colourless, destitute of nectar,
only half the size of the other, and therefore to a certain extent in a
rudimentary state; the pistil is curved towards the perfect nectary, and
the hood formed of the inner petals slips off the pistil and stamens in
one direction alone, so that when a bee sucks the perfect nectary the
stigma and stamens are exposed and rubbed against the ins
