ON SPARGANIUM.
By William H. Beeby.
In previous papers I have dealt principally with the relationship
existing between Sparganinm nimosum and S. nq/Iectum ; 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, S. 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 might
easily be passed over owing to its resemblance to S. viinimum Fries.
The occurrence of S. jJmtans 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.
