20 PERICARP. RECEPTACLE. 



9. The Cone, an enlarged and hardened state of 

 the Catkm, page 9, fig. 2, pi. 6. 



The Pericarp is not an essential part of the 

 fructification, the seeds being frequently naked, and 

 guarded only by the calyx, as in the Ground-ivy, 

 (Glechoma) and all plants of the order to which 

 that plant belongs, fig. 6, pi. 13. 



The Receptacle in its form is either, 

 Plane, as in Yarrow, (Achillea) 

 Convex, as in the Ox-eye. 

 Oblong, as in the Water Crowfoot, fig. 1, pi. 14. 

 Conical, as in the Daisy, (Bellis) figs. 2, 3. 

 Extended and Club-shaped in Arum, fig. 4. 



Its surface is 



Naked in Bellis, fig. 3. 



Dotted in Leontodon, fig. 5. 



Cellular in the Cotton-thistle, (Onopordum) fig. 6. 



Chaffy, having chafflike substances growing from 



it, which separate the florets, as in Chamomile, 



(Anthemis.)
