Classes, from their manner of growth. 



Sub-classes, from their seeds being covered or naked. 



Divisions, from the corolla being divided, undivided, or

Orders are Latin adjectives (feminine plural to agree 

 with iiilantcB, plants, understood), named generally from 

 some leading genus, as Rosacece, the rose family ; Euplior- 

 hiacecB, euphorbia family. 



Generic names are Latin substantives, as ranunculus 

 (from rana, a frog, in consequence of the aquatic habit 

 of some of the species).

 grandiflora.
