DIOECIA. 

 CLASS XXI L 



STAMINA AND PISTILLA IN SEPARATE 

 FLOWERS, AND THE TWO SORTS OF 

 FLOWERS GROWING AT THE SAME TIME 

 ON TWO SEPARATE PLANTS. 



This Class has eight Orders. 



ORDER I. 



No British Plant of this Order. 



NAJA.S. Of this Genus there is but this one monan- 

 species. According to Dr. Smith this plant is a good DRIA : 

 and immutable example of this Order, and the only one stamenj 

 one of which he seems to be certain. It is found 

 wild in the canal between Pisa and Leghorn, and in 

 the Rhine near Basle: it has no Calyx nor Corolla. 



In the Histoire de IS Academic Francois, pub- 

 lished in the year 1719, there is a small figure of this 

 plant which bears the Pistilla, from which the an- 

 nexed figure is copied, and to the present time, no 

 other has been published that I am acquainted with.
