Tr term hypertrophy may serve as a general one 
to comprise all the instances of excessive growth and 
increased size of organs, whether the increase be general 
or in one direction merely. General hypertrophy is 
more a variation than a deformity, unless indeed it be 
caused by insect puncture or the presence of a fungus, 
in which case the excessive size results from a diseased 
condition. For our present purpose hypertrophy may 
be considered as it affects the axile or the fohar organs, 
and also according to the way in which the increased size 
is manifested, as by increased thickness or swelling— 
intumescence, or by augmented length-elongation, by 
expansion or flattening, or, lastly, by the formation of 
excrescences or outgrowths, which may -be classed 
under the head of luxuriance or enation. 
As size must be considered in this place relatively, 
it is not possible to lay down any precise line separating 
what are considered to be the normal dimensions from 
those which are abnormal. 
In practice no inconvenience will be found to accrue 
from this inability to establish a fixed rule, and we may 
say that an hypertrophied organ is one which, from 
some cause or other, attains dimensions which are not 
habitual to the plant: i in its usual, healthy, well-formed 
state. 
It will be seen that under this general head of 
hypertrophy, 1 increase of size, homers brought about, 
is included; thus, not only increase in leneth, but also 
im thickness ; alterations of substance or “consistence, 
no less than of dimensions, are here grouped together.
