254, Grouping of Families. Families are assembled 

 into classes, and these again into larger groups. The 

 details of the entire plan of classification are too compli- 

 cated 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 

 divisions, the first consisting of cryptogams or spore-plants, 

 the second of phanerogams or seed-plants. Here the rela- 

 tions of the various subdivisions may best be shown by a 

 table. 1
