ON SPARGANIUM. 



By William H. Beeby. 



In previous papers I have dealt principally with the relationship 

 existing between Sparganium ramosum and S. neglectum ; on the 

 present occasion it is proposed to offer some remarks on the British 

 species generally. 



The chief aim of my visit to Shetland, in 1886, was to ascertain 

 whether there were present there any of the Scandinavian species 

 of Sparganium beyond those at present known to occur in the British 

 Islands ; one at least of which, 8. hyperboreum Laest., growing 

 as it does both in Norway and in Iceland, might reasonably 

 be looked for in one or other of the lochs and tarns which 

 occur so plentifully scattered over some of the larger of the 

 hundred islands which form the Shetland group. Neither in that 

 year, however, nor in visits made in the three subsequent years, 

 were any of them detected ; and there would not now seem to be 

 any great reason to expect an addition to the number of our species, 

 unless as a rarity in some isolated locality. The above named 

 plant is the one most likely to be found in Britain, and it migbt 

 easily be passed over owing to its resemblance to S. minimum Fries. 

 The occurrence of S. fluitans Fries may be regarded as next in 

 order of probability, whilst the least likely of all to be found, 

 judging by our knowledge of distribution, is S. natans L. With 

 regard to this last name, it may not be out of place to state here 

 clearly how the case really stands.
