ARTIFICIAL SYSTEM, SOMEWHAT REFORMED. 43 



21. Monoecia. Stamens and Pistils in different 

 Flowers, on the same individual plant, fig. 79. 

 Carex pulicaris. 80-84. Quercus Robur. 



22. Dioecia. Stamens and Pistils in different 

 Flowers, on two separate plants, fig. 85-87. 

 Saliv herbacea. 88-91. Populus alba. 



23. Polygamia. Stamens and Pistils separate in 

 some Flowers, united in others, either on the 

 same plant, or on two or three different ones ; 

 such different Flowers being, moreover, dissi- 

 milar in their structure in some other respect, 

 fig. 92-95. Ficus Carica. 



24. Cryptogamia. Stamens and Pistils either 

 imperfectly, or not at all, known, or not capa- 

 ble of being numbered with any precision. 

 See tab. 7-9. 



The Palmaj originally constituted an appendix to 

 this system, because their Flowers were too little 

 known to admit of arrangement by the Stamens and 

 Pistils. But that difficulty is now almost entirely 

 removed, and the Genera of this tribe are mostly 

 found reducible to the 6th, 21st, or 22d Classes. 



The Orders of the first 13 Classes, Monandria to 

 Polyandria inclusive, are characterized solely by the 

 number of the Styles, or sessile Stigmas, in each 

 Perfect Flower (65). These Orders are more or less 

 numerous in the several Classes, and are dis- 

 tinguished as follows.
