118 L1NN/EAN ARTIFICIAL SYSTEM. 



The three first are derived from two words, one denoting number, 

 and the other a brother, because stamens are, figuratively speaking, 

 brothers to each other ; the two last, from words expressing their 

 distinguishing characters. 



16. Monadelphia ; from mono* one, and adelphos, a brother. 



17. Diadelphia ; from dis two, and adelphos, a brother. 



18. Polyadelphia ; from point many, and adelphos, a brother. 



19. Syngenesia ; from sun together, and genes, generation, 

 because the stamens are found united by their anthers. 



20. Gynandria; from gune a pistil, and andros of aner, a stamen, 

 because the pistils are most conspicuous, and have the stamens 

 placed upon them. 



14. Fifth Division : The classes of this part, are 

 established on the principle of the stamens being sepa- 

 rate, that is, not in the same flower, or on the same 

 plant as the pistils, or otherwise. They are the twenty- 

 first, twenty-second, and twenty-third classes. 



21. Monoecia; from mono* one, and oikos a house, because the 

 stamens and pistils are distinct, in separate flowers on the same plant. 



22. Dioecia ; from dis two, and oikos a house, because the stamens 

 and pistils are distinct upon differ ent plants of the same species. 



23. Polygamia; from polus many, and gamos unions, because the 

 stamens and pistils are separate in some flowers, and united in 

 others, either on the same plant, or on two or three distinct plants. 



15. Sixth Division: Is constituted by the class 

 cryptogamia, in which the stamens and pistils are con- 

 cealed, or not perceptible to the naked eye. 



This class is derived from the words krujitos concealed, and gamos 

 unions, from the circumstance just related.

 the divisions of the Linuauui artificial classes, and next
