262. The Groups of Cryptogams. — The arrangement of 
cryptogams into the four great groups given in the pre- 
ceding table is not the only way in which they could be 
classified. It is simply one way of dividing up the enor- 
mous number of spore-bearing plants into sections, each 
designated by marked characteristics of its own. 
The classes given in the table do not by any means 
embrace all known ecryptogams. 
263. The Classes of Seed-Plants.— The gymnosperms 
are much less highly developed than other seed-plants. 
The angiosperms constitute the great majority of seed- 
plants (or, as they have been more commonly called, 
flowering plants). 
When people who are not botanists speak of plants 
they nearly always mean angiosperms. This class is more 
interesting to people at large than any other, not only on 
account of the comparatively large size and the con- 
spicuousness of the members of many families, but also 
on account of the attractiveness of the flowers and fruit 
of many. Almost all of the book which precedes the 
present chapter (except Chapter v) has been occupied 
with seed-plants.
