APPENDIX. 



Of the Signs and Abeeviatioxs employed in Botanical Writings. 



LiNXiEUS adopted the following signs for designating the duration of a 

 plant, viz. : — 



^ An annual plant. 

 ^ A biennial plant. 

 21 A perennial herb. 

 \i A shrub or tree. 



Among the signs recently introduced, the following have come into 

 general use : — 



O A mouocaiiiic (once-flowering) plant, whether annual or biennial. 



® An annual plant. 



(§) A biennial plant. 



21 A perennial herb, 



\ A plant with a woody stem.

! The exclamation point is employed as the counterpart of the note of 

 interrogation. When it follows the name of an author appended to 

 the name of a plant, it imports that an authentic specimen of the 

 plant in question, under this name, has been examined by the writer: 

 when it is appended to a locality, it signifies that the writer has seen or 

 collected sjjecimens of the plant from that locality, &c. 



? The note of interrogation is employed to denote doubt or uncertain- 

 ty- ; and is affixed either to a generic or specific name, or to that of an 

 author or localitj^ cited. 



* As used by De Candolle, indicates that a good description is found at 

 the reference to which it is appended. It is not in common use.
