3. CLASSIFICATION 



We have divided the vegetable creation into two great classes, 

 the flowering plants and the flowerless plants (427, 4376). The former 

 are known also as phanerogams and spermatophytes (seed-bearing 

 plants). The latter are cryptogams. 



The cryptogams, exclusive of bacteria, have been thrown into 

 three groups (437a): Thallophytes ; Bryophytes : Pteridophytes or 

 vascular cryptogams (427). 



The phanerogams or spermatophytes are divided into gymno- 

 sperms and angiosperms (376, ;!76fflJ.
