outer wall of each cell, but the placentae however would
seem to have an obvious connexion with the axis, although this is very
doubtful.

The formation of the stigma decidedly indicates a binary formation of
carpella.

If these 4 upper cells are 4 constantly, and the base of the ovary is as
constantly two celled, then the explanation is sufficiently obvious,
though different from that given by Lindley. {113}

First, we have in the bottom from which the mere structure of an ovary is
deduced, the normal dicarpellary structure, and there is in addition a
tendency in excess toward a parietal placentation.

The anomalous formation arises first from parietal placentae being
produced to the axis, and from spurious growth from the sides of the
ovary also meeting in the axis, by which the ovula are divided into four
bundles.

Lindley's view seems to be questionable, because as in all cases the
styles and stigmata are more permanent than ovaries, there should be as
many styles, etc. as ovaries. 2nd, because according to this view the
placental suture of the carpella would be turned from the axis, (look at
Pomaceae,) although his view of Pomaceae being right would indicate an
additional affinity with Mespilus, etc. which it does in habit and
abbreviated lateral branches.

Are all Myrtaceae dicarpellar?

The true nature of the case is pointed out in the instance cited by
Lindley of a permanent variety of apple, which has 14 cells and 14
styles! With regard to Nicotiana and Nolana; have these one or two rows
of carpella?
