express the plan of the flower, and thus includes the arrangement, form,
and number of its component elements.

PART I.

STASIMORPHY.[219]

Deviations from the ordinary form of organs arising from stasis or
arrest of development are included under this heading.

There are many cases in which the forms proper to a juvenile condition
of the plant are retained for a much longer period than ordinary, or
even throughout the life of the individual growth goes on, but
"development" is checked. Such conditions may even be propagated by seed
or bud. It is a very general thing for botanists to consider these cases
as reversions to a simpler, primitive type, and this may be so; but on
the other hand, they may be degenerations from a complex type, or they
may have no direct relation to any antecedent condition. Stasimorphic
changes affecting principally the relative size of organs--such, for
instance, as the non-development of internodes, or the atrophy or
suppression of parts will be found mentioned in the sections relating to
those subjects. In the present part those alterations which affect the
form of organs principally are treated of.

CHAPTER I.

PERSISTENCE OF JUVENILE FORMS.

The retention in adult life of a form characteristic of an early stage
of development, and therefore usually transient, may be manifested in
any of the organs of the plant. As these cases are for the most part
treated under separate headings, it is here only necessary to allude to
a few, which it is difficult to allocate satisfactorily, while the
reader may be referred for other instances of like nature to the
sections on Peloria, Atrophy, Suppression, Dimorphy, Substitutions, &c.

=Stasimorphy in the leaves of conifers.=--In many conifers the leaves
produced in the young state of the plant are different, both in
arrangement and form, from those subsequently developed (see pp. 89,
90). But it occasionally happens that the plant continues to form
throughout its existence leaves such as are usually produced only in a
young state; thus M. Gubler ('Bull. Soc. Bot., Fr.,' vol. viii, 1861, p.
527) describes a plant of _Pinus pinea_ in which the primordial, usually
transitory, foliage was permanent, leaves of the ordin
