8. VIOLACE^: (Viola odorata) Sweet Violet. 

 (Viola tricolor) Heart's-ease. 



The well known Sweet-smelling

 one, the Cephaelis Ipecacuanha, 

 which produces the well-known 

 emetic bearing that name.

9. DROSERACE.E (Drosera rotundifolia) Sun-dew. 



The Sun-dew is so called from the 

 globules of a sort of viscid liquid 

 excreted by the hairs of this 

 plant while in sunshine, and 

 looking like dew ; some species 

 of this order have their leaves 

 so irritable that an insect alight- 

 ing on them causes them to shut 

 up and catch it, hence the name 

 "Venus's Fly Trap" (Dionea 

 muscipula) which is given to an 

 American species. 



Sun-dew.
