 Groves) : Groves i8g^. 



As the Messrs. Groves discovered this inconspicuous plant in 

 the only two sets of bog-holes they had the opportunity of 

 examining, they have little doubt that it will be found to be much 

 more generally distributed in Ireland when the many si(itable 

 localities the country affords have been investigated. In Great 

 Britain the plant has been found only in Cambridgeshire and 

 Anglesea. 



Pirst found in Ireland, by Messrs. Groves and H. C. Levinge, 

 near Lough Owel, in 1892.
