been fertilised by their own pollen, and they
included pale brown seed; and two which had been crossed by pollen from
the purple kind, and they included seeds all deeply tinged with black.
These latter seeds yielded purple-flowered plants like their father;
whilst the pale brown seeds yielded normal red-flowered plants; and
Major Clarke, by sowing similar seeds, has observed on a greater scale
the same result. The evidence in this case of the direct action of the
pollen of one species on the colour of the seeds of another species
appears to me conclusive.

In the foregoing cases, with the exception of that of the purple-podded
pea, the coats of the seeds alone have been affected in colour. We shall
now see that the ovarium itself, whether forming a large fleshy fruit or a
mere thin envelope, may be modified by foreign pollen, in colour, flavour,
texture, size, and shape.

The most remarkable instance, because carefully recorded by highly
competent authorities, is one of which I have seen an account in a
letter written, in 1867, by M. Naudin to Dr. Hooker. M. Naudin states
that he has seen fruit growing on _Chamaerops humilis_, which had been
fertilised by M. Denis with pollen from the Phoenix or date-palm. The
fruit or drupe thus produced was twice as large as, and more elongated
than, that proper to the Chamaerops; so that it was intermediate in
these respects, as well as in texture, between the fruit of the two
parents. These hybridised seeds germinated, and produced young plants
likewise intermediate in character. This case is the more remarkable as
the Chamaerops and Phoenix belong not only to distinct genera, but in
the estimation of some botanists to distinct sections of the family.

Gallesio[933] fertilised the flowers of an orange with pollen from the
lemon; and one fruit thus produced bore a longitudinal stripe of peel
having the colour, flavour, and other characters of the lemon. Mr.
Anderson[934] fertilised a green-fleshed melon with pollen from a
scarlet-fleshed kind; in two of the fruits "a sensible change was
perceptible; and four other fruits were somewhat altered both
internally and externally." The seeds of the two first-mentioned fruits
produced plants partaking of the good properties of both parents. In
the United States, where Cucurbitaceae are largely cultivated, it is the
popular
