3rd Column. — T he Natural Orders. 
The Natural Orders are founded on Structural Affinities ; and the plan of numerical reference adopted in the present work 
will prove of essential service to the Amateur in forming, by comparison, an opinion of any plant in this Catalogue which may 
be unknown to him : for instance, Anayallis, Cyclamen, Dudecatheon, Primula sinensis, and Auricula belong to the same Na- 
tural Order, “ Primulaceee,” No. 160 j consequently, should Doilecatheon be unknown, the knowledge of one or more of the 
others would greatly assist in forming an opinion of it. In making comparisons, however, the height of the plant should be 
considered : for example, the Aster and Daisy belong to the same Natural Order, “ Composites, ” No. 98 ; and at first sight 
there does not appear much resemblance between them, there being so much difference in the size of the flowers and the 
height of the plants.
