one species only, or several species are included under 

 the above quoted names. Howsoever tliis question may 

 eventually be answered and settled, it is at present impos- 

 sible to separate their localities and properly refer them 

 to the several varieties or species. In his ' History of 

 British Ferns ' Mr. Newman enumerates the names of 

 seventeen counties, for which he possesses lists of ferns, 

 and says that the Cystopteris is absent from all of them. 

 It has, however, been reported from five of those counties, 

 and recently in print on very good authority from two of 

 them, Sussex and Leicester. Those of Dorset and North- 

 ampton, resting on old authoritj', it would be desirable to 

 have verified afresh ; the fifth county, Norfolk, was re- 

 ported to me by Mr. S. P. Woodward.

Alien. On a wall at Low Layton, in Essex, supposed 

 to have been planted there. Under name of C. regia, this 

 fern has been by some botanists identified or confused 

 with a native fern of North Wales and the Highlands, 

 corresponding in part with C. dentata of our descriptive 

 Floras.
