302 LINNiEAN 



24. Cryptogamia. Stamens and Pistils either not 

 well ascertained, or not to be numbered with any 

 certainty, insomuch that the plants cannot be re- 

 ferred to any of the foregoing Classes. Of this 

 Ferns, Lichens, Sea-weeds and Mushrooms are 

 examples. 



Appendix. PALMiE, Palm-trees, a magnificent 

 tribe of plants, chiefly tropical, whose flowers were 

 too little known, when Linnaeus wrote, to serve the 

 purposes of classification; but they are daily clearing 

 up, and the Palms are found generally to belong to 

 the Classes Alonoecia, Dioecia, or He.vandria. 



The Orders of the Linnaean System are, in the 

 first thirteen Classes, founded on the number of the 

 Styles, or on that of the Stigmas when the Styles are 

 wanting, which occurs in Viburnum. Such Orders 

 are accordingly named 



MoNOGY'NiA. Style, or sessile Stigma, 1. 



DiGYNiA. Styles, or sessile Stigmas, 2. 



Trigynia 3. 



Tetragynia 4. 



Pentagynia 5. 



Hexagynia — 6, 



of very rare occurrence. 



Heptagi^nia 7, 



still more unusual.
