216 ELEMENTS OF BOTANY. 
261. Grouping of Families. — Families are assembled into 
classes, and these again into larger groups. The details of 
the entire plan of classification are too complicated for any 
but professional botanists to master, but an outline of the 
scheme may be given in small space. 
The entire vegetable kingdom is divided into two great 
series, the first consisting of eryptogamous or flowerless 
plants, the second of phanerogamous or flowering plants. 
Here the relations of the various subdivisions may best be 
shown by a table.’

1 This is, of course, only for consultation, and not to be committed to memory by 
the student. 
2 The teacher will notice that this table is carried out a little more in detail than 
that of Series I, since its subject-matter is more familiar and the number of classes 
of phanerogams is so much smaller than that of cryptogams.
