ited bearing a truss of flowers of _A. Ind. Gledstanesii_
"as true as could possibly be produced, thus evidencing the origin of
that fine variety." On another plant of _A. Ind. variegata_ a perfect
flower of _A. Ind. lateritia_ was produced; so that both _Gledstanesii_
and _lateritia_ no doubt originally appeared as sporting branches of
_A. Ind. variegata_.[831]

_Cistus tricuspis._--A seedling of this plant, when some years old,
produced, at Saharunpore,[832] some branches "which bore leaves and
flowers widely different from the normal form." "The abnormal leaf is
much less {378} divided, and not acuminated. The petals are
considerably larger, and quite entire. There is also in the fresh state
a conspicuous, large, oblong gland, full of a viscid secretion, on the
back of each of the calycine segments."

_Althaea rosea._--A double yellow Hollyock suddenly turned one year into
a pure white single kind; subsequently a branch bearing the original
double yellow flowers reappeared in the midst of the branches of the
single white kind.[833]

_Pelargonium._--These highly cultivated plants seem eminently liable to
bud-variation. I will give only a few well-marked cases. Gaertner has
seen[834] a plant of _P. zonale_ with a branch having white-edged
leaves, which remained constant for years, and bore flowers of a deeper
red than usual. Generally speaking, such branches present little or no
difference in their flowers: thus a writer[835] pinched off the leading
shoot of a seedling _P. zonale_, and it threw out three branches, which
differed in the size and colour of their leaves and stems; but on all
three branches "the flowers were identical," except in being largest in
the green-stemmed variety, and smallest in that with variegated
foliage: these three varieties were subsequently propagated and
distributed. Many branches, and some whole plants, of a variety called
_compactum_, which bears orange-scarlet flowers, have been seen to
produce pink flowers.[836] Hill's Hector, which is a pale red variety,
produced a branch with lilac flowers, and some trusses with both red
and lilac flowers. This apparently is a case of reversion, for Hill's
Hector was a seedling from a lilac variety.[837] Of all Pelargoniums,
Rollisson's Unique seems to be the most sportive; its origin is not
positively known, b
