attached, not to the receptacle, but to the calyx,* 

 the rose tribe being the first examples. Another 

 advance brought us to plants which, instead of 

 having many-pieced corollas, had them all in one 

 piece,t but still with the same attachment as the 

 last named many-petaled, to the calyx ; and now in 

 our fourth step we find ourselves retui"ning to the 

 receptacle attachment as at first, only with mono- 

 petalous corollas. To make the above more clear, 

 we subjoin the following table, which is a slight 

 simplification of that prefixed to that best of British 

 Floras, Hooker and Arnott's : — 



Corolla and stamens inserted on recep- 

 tacle, represented by buttercups »ad

Corolla and stamens mserted on recep-

A glance will now tell our traveller in Flora's 

 realms the ground he has already gone over, and, 

 as we find ourselves in the fourth or last division, 

 we agaiu return to our primroses and their con- 

 geners. We should teU you, however^ that in this 

 last division there is yet a sub-division into plants
