Observation I.-There is a species OF
Citrus known in Italy by the name OF
bizzaria, and in France by that of the
hermaphrodite orange (aurantium limo
cltr itum, folio ct .fructO nsirtO) and which
bears at the same time sour oranges,
lemons, citrons and mixed fruits.
| have observed upon this hybrid that
the same branch bears at the same time
leaves and flowers, OF which some an
nounce the sour orange tree, others the
lemon, and still others the citron tree.
They produce fruit which belong some
times to one of these species, at other
times to two, or even three of them
mixed.
A scion which springs up violet often
develops branch, some of whose flow
ers are violet, others white, and the buds
of this branch grated upon another
stock sometimes produce there the cap
rices OF the variety, and sometimes per-
petuate simple sour orange, although
they may have been taken from the aXil
of citron leaf; and reciprocally sim
pie citron, though taken from the aXil of
a sour orange leaf
This caprice has forced the gardeners
to multiply it by the layer It is thus
that this hybrid is perpetuated without
degenerating.
Observation III fecundated white
pinks with red pinks reciprocally. The
seeds thus produced gave pinks of mixed
flower. Several of these plants present.
ed the following phenomena: The same
plant which gave mixed flowers gave
some flowers entirely white, and others
entirely red. One year gave only red
flowers, and the next mixed flowers
again. Others, after having produced
mixed tiowezs ttsso or three years, sybsc
seemed entirely to have returned to the
species. ,. z
Observation Iu.-Similar to the bikar-l
rerie is the violet sour orange, SwhichslsI
cultivated at Paris tcitrus Ga,rdnt'a'n
indicun tructa CioIaces). | have noticed
in the specimen growing III the Jardln
dies Plantes that of the flowers springing
from the same branch-some were white
like those of the orange tree, and others
violet. like those of the lemon tree-a
variation appearing equally in the fruit;
Others have observed in individuals OF
this race that this caprice may appear
one year, be wanting the second, and re-
appear the third year.
0bserrdtion IJ.-With the pinks,. OF
whichI spoke above, may be compared
the streaked orange trees Citrus 0urdntt-
u0, folio ct fructu rdriegdto). l have seen
some or them which developed branches
inno way affected by that yellowish bor-
der which marks the foliage OF these
trees; and have seen this caprice reap
near in others after it had almost been
lost for years. -9,
Observation T.-The gardeners OF III
euria have practice of separating from
other cabbages the caulifiower, destined
for seed, by transporting them into $50
lated gardens, and surrounding them by
a sort of enclosure OF branches or straw
in order to preserve them from the ln1iu-
ence of the other species.
Owing to this precaution vegetable
gardens present only plants OF the ordl-
nary form. n.

been gathered from plants of these two
snecies, which had been sown pell-mel
in the same bed, and almost every heao
had curled and streaked leaves.
CONSEQUENCES.
The pollen of one species acting upol
the ovary of another, produces modlil
cation in the seed which results from 1t
