 OF VEGETABLES, AND THEIR PARTS. 



VEGETABLES are divisible into the seven families 

 or tribes following*, viz. 



1. FUNGI, Mushrooms. 



2. ALGAE, Flags; whose root, leaf, and stem are 

 all one. 



3. Muse i, Mosses ; whose antherae have no fila- 

 ments, and are placed at a distance from the female 

 flower, and whose seeds also want their proper tunic 

 and cotyledons. 



4. FILICES, Ferns; whose fructification is on the 

 back of the Frondes f. 



* This natural division of vegetables into several tribes be. 

 ing given in the Philosophia Botanica, we wertf unwilling to 

 omit it; but it is necessary to give the reader a caution, lest 

 he confound it with the artificial or systematic distribution of 

 plants explained in the second part of this work ; the division 

 here given is drawn from a consideration of the whole vege- 

 table ; whereas the systematic or artificial distribution into 

 twenty.four classes is grounded on the fructification only.
