Synopsis of a new Classification of the Vegetable Kingdom. 

 By Theodore C. Hilgaed, M. D. 



"We lay before the public the result of our observations on the natural connec- 

 tions among vegetable forms (relationship), demonstrating them to form a single 

 file of transitions or total resemblances, from the first to the last ; and further- 

 more, showing what can be claimed as absolute relations and what as accidental 

 relation or parallelism ; which parallelisms, if repeated, form laws of rhythmic 

 approximation or collateral relationship ; and under any consideration furn- 

 ishing, we believe, a consistent base for consistent researches on the laws of pro- 

 gressive vegetable development^ and, it may be, organic development generally. At 

 present, occupied with a complete expose and qualification of this scheme, we 

 would be happy beforehand to draw the attention and efforts of botanists, placed 

 mostly under more favorable circumstances than ourselves, to the high import- 

 ance of this question generally, and to thus solicit their own ideas, observations 

 and communications 07i their own grounds^ by which, doubtless, much prolific 

 material might be prepared, elicited and collected. 



In the present scheme, we have noted our principal suggestions of relations 

 hitherto not generally adopted or even known before, by *, by which we mean to 

 imply a very close relationship. If thus a member is introduced among a group 

 of families of acknowledged general afiBnity, it will of course be found enclosed 

 between two stars ; for a mere serialization, according to our views, of families 

 notoriously related, we give no express mark, leaving it to the interest of the 

 reader to compare with their various previous serializations.
