axile

1 Section of seed of Violet; anatropous with straight axile embryo in the albumen.

2 The placentation is constantly axile in the inferior row and parietal in the upper one.

3 Excrescences from axile organs—Warts.—In a preceding paragraph the formation of gnaurs has been alluded to.

4 Adhesion of foliar to axile organs.—The appendicular organs may likewise be found united to the axile ones.

5 In such a case the placent� are naturally axile, or all brought together in the axis or centre; and the ovary has as many Dissepiments, or internal Partitions, as there are carpels in its composition.

6 Enlargement of axile organs.—All the species of Pelargonium, Geranium, Mirabilis, as well as those of Caryophylleæ and other orders, have tumid nodes as a normal occurrence.

7 The ovary is partially adherent, is surmounted by a style, and has two or three loculi with an axile placenta, to which several small curved ovules are attached.

8 Change in the direction of axile organs, roots, stems, &c.—The roots frequently exhibit good illustrations of the effect of the causes above mentioned in altering the natural direction.

9 The disjunction or dialysis of the carpels, for instance, frequently renders axile placentation marginal.

10 In malformed flowers of Digitalis the change from axile to parietal placentation may often be seen.

11 Abortion of axile organs.—When the main stem is arrested in its growth, the habit and general appearance of the plant are materially altered, as in the so-called stemless plants, plantæ acaules.
