est was of the usual copper
colour.

The following cases are highly remarkable. Mr. Rivers, as I am informed
by him, possessed a new French rose with delicate smooth shoots, pale
glaucous-green leaves, and semi-double pale flesh-coloured flowers
striped with dark red; and on branches thus characterised there
suddenly appeared, in more than one instance, the famous old rose
called the Baronne Prevost, with its stout thorny shoots, and immense,
uniformly and richly coloured, double flowers; so that in this case the
shoots, leaves, and flowers, all at once changed their character by
bud-variation. According to M. Verlot[860] a variety called _Rosa
cannabifolia_, which has peculiarly shaped leaflets, and differs from
every member of the family in the leaves being opposite instead of
alternate, suddenly appeared on a plant of _R. alba_ in the gardens of
the Luxembourg. Lastly, "a running shoot" was observed by Mr. H.
Curtis[861] on the old Aimee Vibert Noisette, and he budded it on
Celine; thus a climbing Aimee Vibert was first produced and afterwards
propagated.

_Dianthus._--It is quite common with the Sweet William (_D. barbatus_)
to see differently coloured flowers on the same root; and I have
observed on the same truss four differently coloured and shaded
flowers. Carnations and pinks (_D. caryophyllus_, &c.) occasionally
vary by layers; and some kinds are so little certain in character that
they are called by floriculturists "catch-flowers."[862] Mr. Dickson
has ably discussed the "running" of particoloured or striped
carnations, and says it cannot be accounted for by the compost in which
they are grown: "layers from the same clean flower would come part of
them clean and part foul, even when subjected to precisely the same
treatment; and frequently one flower alone appears influenced by the
taint, the remainder coming perfectly clean."[863] This running of the
parti-coloured flowers apparently is a case of reversion by buds to the
original uniform tint of the species.

I will briefly mention some other cases of bud-variation to show how
many plants belonging to many orders have varied in their flowers;
numerous cases might be added. I have seen on a snap-dragon
(_Antirrhinum majus_) white, pink, and striped flowers on the same
plant, and branches with striped flowers on a re
