575. The twenty-four classes of Linnaeus were founded upon 

 something about the stamens. The following is an analysis of 

 them. The first great division is into two great series, the Phce* 

 nogamous and the Cryptogamous, the same as in the Natural System. 

 The first of these is divided into those flowers which have the sta- 

 mens in the same flower with the pistils, and those which have not ; 

 and these again are subdivided, as is shown in the following tabular 

 view. 



Series I. PH^ENOGAMIA ; plants with stamens and pistils, i. e. with reaj 



flowers. 



I Stamens in the same flower as the pistils : 

 * Not united with them, 

 H- Nor with one another. 



w. Of equal length if either 6 or 4 in number. 



w. -w Of unequal length and either 4 or 6. 



Four, 2 long and 2 shorter, 14. DIDYNAMIA. 



Six, 4 long and 2 shorter, 15. TETRADYNAMI^ 



H- - United with each other, 

 By their filaments, 



Into one set or tube, 16. MONADELPHIA 



Into two sets, 17. DIADELPHIA. 



Into three or more sets, 18. POLYADELPHI. 



By their anthers into a ring, 19. SYNGENESIA. 



# # United with the pistil, 20. GYNANDRIA. 



li. Stamens and pistils in separate flowers, 



Of the same individuals, 21. MON<ECIA. 



Of different individuals, 22. DICECIA. 



Some flowers perfect, others staminate or 

 pistillate either in the same or in different 

 individuals, 23. POLYGAMIA. 



Series II. CRYPTOGAMIA. No stamens and 

 pistils, therefore no proper flowers, 24. CRYPTOGAMI*.
