NOTICE. 



This Synoptical Mantissa being a Supple- 

 ment to all the works on Dendrology and Xylo- 

 gy, as well as to my own : those New G. and Sp. 

 of Trees and Shrubs already described by my- 

 self in my various works and Floras, above all 

 my two late FLORA TELLURIAN A and FLORA OF 

 NORTH AMERICA, as well as my MEDICAL 

 FLORA of the United States, will seldom be no- 

 ticed or repeated here. 



The whole of the New Genera of such Trees; 

 will be duly reduced to their natural orders, and 

 a Table formed of them : so as to present at 

 once a view of the generic additions to these 

 natural groups, and a proper classification of 

 such additional Discoveries or Revisions. 



But few Genera of which only the flowers 

 are known and not the fruit, or viccversa, will 

 be introduced ; but some may, as did Gaertner 

 and others when they only obtained imperfect 

 materials or figures.
