cient reason that the facts of the case are otherwise, and are so stated 

 as clearly as the general plan of the Catalogue would admit in the 

 individual instance. The retention of E. limosura in the general list 

 of the ' London Catalogue ' should show that our common plant, so 

 commonly mentioned by that name, is held a true native ; while the 

 position of E. fluviatile among the " Excluded Species," with the in- 

 verted commas ("L."), and the added note of interrogation (?), should 

 show also that something more than a mere name was intended to be 

 quoted and queried. The latter is the plant mentioned under the 

 same name by Fries and Babington, concerning which some more 

 satisfactory information seems required before we can introduce it 

 into our list of certainties. 



Equisetum limosum (Lond. Cat.) = E. limosum of Smith, Hooker, 

 Babington, &c; E. fluviatile of Newman. 



Equisetum fluviatile (Lond. Cat.) = E. limosum, @. fluviatile of 

 Babington; not E. fluviatile of Newman.
