form of ^. ampeloprasum, itself a naturalised species." (J. D. H. ) 



70. Potamogeton Griffithii ( Ar. Bennett) . Carnarvon. ' ' Nearest to this is a 



probable hybrid from N. America, but not identical. " (Ar. Bennett. )

''This is a variety of a sub-species of the common S. palustrisj''

75. Luzula pilosa (Willd.), var. Borreri (Bromf,). "Perhaps a hybrid." 



(Groves. ) 



76. *Carex involuta (Bab.). Cheshire. *'A distinct enough plant, but 



probably a hybrid between C. vesicaria and C. ampullacea, found 

 in one place only." (J. D. H.) 



77. Carex glauca (Murr.), var. stictocarpa (Sm.). Scotland. 



78. Carex proecox (Jacq. ), ^•a?•. capitata (Ar. Benn. ). Ireland. ** A remark-

79. *Carex Grahami (Boott). "A mountain form of G. vesicaria.''' (J. 



D. H.) 



80. *Spartina Townsendi (Groves). Hampshire. ** Perhaps a hybrid."

of the protean P. nemoralis.^^ (J. D. H.) 



86. Bromus mollis (L.), 'y<xr. interruptus (Hackel). *' Possibly a colonist 



of unknown origin. Perhaps a monstrosity." (Groves.) 



Even should it ultimately prove that none of the 

 more or less doubtful forms are found to be peculiar 

 British varieties, yet the number admitted after so rigor- 

 ous an examination is about what we should expect in 

 comparison with the limited amount of speciality we have 

 seen to exist in other groups. The three or four Ameri- 

 can species which inhabit the extreme west and north- 

 west of the British Isles, but are not found on the con-
