=Phyllody of the corolla.=--The petals also are frequently replaced by
leaves, though in many of the recorded instances the change has been one
of colour only; these latter are strictly cases of virescence. M.
Seringe[259] speaks of a flower of _Peltaria alliacea_ in which the
calyx was petal-like, while the corolla was leafy as if there had been
transposition of the two organs, a very rare, if not unparalleled,
instance. In a flower of _Campanula Medium_, provided, as is often the
case, with a double corolla, the outer corolla was slit down on one
side, the edges of the cleft being leafy.

The frondescent petals are very often completely disjoined, as in
_Verbascum nigrum_, and _Lonicera Periclymenum_, in which, moreover,
median prolification generally coexists. In the case of _Tropaeolum
majus_, the ordinary leaves of which are peltate and orbicular, the
petals when frondescent have not the peltate arrangement, but are
spathulate, and provided with very long, narrow stalks, so that, in some
cases, they are, more properly speaking, enlarged virescent petals than
true leaves; in other instances, however, the arrangement of the veins
is more like that of the true leaves than that of the petals.
As might be expected, frondescenc
