STAMINA AND PISTILLA IN SEPARATE 

 FLOWERS, AND THE TWO SORTS OF 

 FLOWERS GROWING AT TILE SAME 

 TIME ON TWO SEPARATE PLANTS. 



This C/ass has eight Orders. 



NAJAS. According to Dr. Smith, this plant 

 is a good and immutable example of this Order, 

 and the only one of which he seems to be certain. 

 It is found wild in the canal between Pisa and Leg- 

 horn, and in the Rhine near Basle ; it has no Calyx 

 nor Corolla. 



In the Histoire de LAcademie Francois, published 

 in the year IJ lg, there is a small figure of this plant 

 which bears the Pistilla, from which the annexed 

 figure is copied, and down to the present time there 

 has been no other published; a circumstance hardly 

 to be credited, in the greatly improved state of 

 botanical knowledge, and the ardour with which 

 it has been cultivated in the different countries of 

 Europe 3 yet it is still more extraordinary, that of 

 the common Sensitive Plant, Mimosa Pudica, there 

 never has been any representation of any credit, and 

 the best, which is exceedingly worthless, was pub- 

 lished so long ago as the year l6p/. f 



f The work in which this figure is to be found, is entitled 



Order t. 

 One Suaiea.
