Devtations 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 ‘“develop- 
ment” is checked. Such conditions may even be pro- 
pagated 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 ante- 
cedent condition. Stasimorphic changes affecting 
principally the relative size of organs—such, for in- 
stance, 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.
