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

 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
