ollen. I shall
hereafter give {377} cases of apple-trees which regularly produce fruit
of two kinds, or half-and-half fruit; these trees are generally
supposed, and probably with truth, to be of crossed parentage, and that
the fruit reverts to both parent-forms.

_Banana_ (_Musa sapientium_).--Sir R. Schomburgk states that he saw in
St. Domingo a raceme on the Fig Banana which bore towards the base 125
fruits of the proper kind; and these were succeeded, as is usual,
higher up the raceme, by barren flowers, and these by 420 fruits,
having a widely different appearance, and ripening earlier than the
proper fruit. The abnormal fruit closely resembled, except in being
smaller, that of the _Musa Chinensis_ or _Cavendishii_, which has
generally been ranked as a distinct species.[827]

FLOWERS.--Many cases have been recorded of a whole plant, or single
branch, or bud, suddenly producing flowers different from the proper
type in colour, form, size, doubleness, or other character. Half the
flower, or a smaller segment, sometimes changes colour.

_Camellia._--The myrtle-leaved species (_C. myrtifolia_), and two or
three varieties of the common species, have been known to produce
hexagonal and imperfectly quadrangular flowers; and the branches
producing such flowers have been propagated by grafting.[828] The
Pompone variety often bears "four distinguishable kinds of
flowers,--the pure white and the red-eyed, which appear promiscuously;
the brindled pink and the rose-coloured, which may be kept separate
with tolerable certainty by grafting from the branches that bear them."
A branch, also, on an old tree of the rose-coloured variety has been
seen to "revert to the pure white colour, an occurrence less common
than the departure from it."[829]

_Crataegus oxycantha._--A dark pink hawthorn has been known to throw out
a single tuft of pure white blossoms;[830] and Mr. A. Clapham,
nurseryman, of Bradford, informs me that his father had a deep crimson
thorn grafted on a white thorn, which, during several years, always
bore, high above the graft, bunches of white, pink, and deep crimson
flowers.

_Azalea Indica_ is well known often to produce by buds new varieties. I
have myself seen several cases. A plant of _Azalea Indica variegata_
has been exhib
