ANATOMY OF TISSUES. tl 
show a distinct separation into meristem and lasting tissue, the 
urmeristem of the higher plants being represented by a single 
apical cell, or by a number of meristem cells. Among plants 
of the latter class a method of growth described as peculiar to 
s the fungi is sometimes found. Dif- 
ferent species of Fucus, for example, 
form the larger part of their tissues 
by cell division in the apical region, 
but in addition to this, long cyhn-

drical cells grow out in various parts of the plant, pushing their 
way between the other cells, in a manner closely resembling the 
growth of the fungous hyphae. A good example of growth 
from a single apical cell is found in the genus Stypocaulon, 
which grows in such a manner as to suggest the stem and
