1 :;■_'.".. A.GAKDH, Carl von. — (Classes Plantarum). 

 This is a duodecimo pamphlet of 22 pact's, with :i coloured map, and is a recapitulation 

 of the views of classification promulgated by its author between 1821 and 1826, in his 

 I risiiti Botcmici. The object is to group Natural Orders in Classes, that is to say, 

 in ili\isi..n- subordinate to the primary ramifications of a system, and equivalent to my 

 .Mli.'inci -. "Classes," says Bishop A gardh, "should be formed by the same rules and 

 on the same principles ^ < lencra and * (rders ; and therefore not by the breaking up of 

 higher groups, but by the gathering together of lower groups. Yet, up to this time, all 

 the so-called natural classes of plain- have been formed upon an opposite principle, with 



the exception of the arrangement of BatBch. We must distinguish, with Linnteus, 



Ik twt i ii the character of a plant and its affinity. The former is derived from the latter, 

 and not pi l'lant- will Bomi times agree in very few characters, which never- 



theless arc bound together by the strongest possible affinity. For instance, Ceratonia is 

 rory different from Leguminous plants, and Fraxinus from Jasmines; yet they are 

 Dearly allied."' 



Agardh's primary divisions are nine ■ namely, 



I. Acotyledons. 



I, P ad i dons. 



8. Oryptoootyledons. 

 I. Phaaerocotyledona j incomplete. 



' i complete, hypogynous, monopetalous. 



— polypetalous. 



igynous, monopetalous. 

 -i , polypetalous. 



MIOUS. 



But he adds, that the perigynous and diacigynous structures run together, and that no 

 ttxed difference can be found between the monopetalous and polypetalous conditions. 



The Classes or Alliances whieli are formed within these primary groups are contrived 

 without sufficient regard to the definitions which precede them, and by which alone 

 tin y are to be recognised. In fact, the principle of disregarding characters and trusting
