 I believe Hybrids are frequently produced among the Einlohia, as is 

 known to be the case in Carduus, Verhascum, and some other genera. I 

 have frequently met with spechnens looking like hybrids between E. 

 tnontanum, and E. lanceolatuin, growing with these two ; also with others 

 apparently bet\A een E. laiiceolatum and E. ohscurum; and less frequently 

 with specimens having characters between E. parviflorum and E. lanceo- 

 latum; and E. parviflorum and E. tetragonum. I have several apparent 

 hybrids preserved in my Herbarium. 



(Enothera hiennis, L. Thicket, Manadon Hill. Queen Anne's Battery, 

 Plymouth ; Keys, Fl. ii. 151. Alien. Planted, or else ' an escape ' from 



cultivation. 



(E. odorata, Jacq. Alien. " I possess a specimen from Laira, Ply- 

 mouth, collected by Mr. Keys, and Mr. Briggs has sent me examples 

 collected there in 1862." BosiveU, in E. B. ed. 3. iv. 26. At Plymouth. 

 Bah. Man. ed. 7, 131. Alien. I found it near the toll-gate by the first 

 embankment from Plymouth, but have not seen it for several years past. 

 Perhaps the examples referred to under (E. biennis really belonged to 

 (E. odorata.

 The creeping root-stock of this renders it a difficult plant to eradicate, 

 and it proves a troublesome weed in some gardens. I have known 

 poisonous properties to be attributed to it through its having been con- 

 fused with ' Deadly Nightshade. '
