Plants -- Abnormalities
In hermaphrodite flowers of _Carica Papaya_ (fig. 103) there is a single
row of five stamens instead of two rows of five each as in the normal
male flowers, the position of the second or inner row of stamens being
occupied by five carpels, which, however, are not adherent to the
corolla as the stamens are, thus, supposing the arrangement of parts in
the normal male flowers to be as follows:
---------------------------
s s s s s
---------------------------
| p p p p p
| st st st st st
| st st st st st
|
That of the hermaphrodite blossoms would be, in brief, as follows:
| 5 s
|------------
| 5 p
| 5 st
| 5 c
|
One of the most curious cases of this kind recorded is one mentioned by
Mr. Berkeley,[209] wherein a large white-seeded gourd presented a
majority of flowers in which the pollen was replaced by ovules. It would
seem probable from the appearances presented by the figure that these
ovules were, some of them, polliniferous, like those of the
_Passiflora_, &c., described at p. 185, but nothing is stated on the
subject.

stamens, &c.

[191] Professor Dickson concludes from the examination of these
structures that the male cone, consisting of simple stamens developed on
one common axis, must be regarded as a simple male flower, while the
axillary scales of the female cone are by him compared with the
flattened shoots of _Ruscus_.
