see why lagopina, Wahl. (1803), should be dropped, unless indeed 
Richter is right in quoting C. Lachenalii, Schkr. (1801), as equalling 
lagopina. Of course the question resolves itself into this : Is it lawful 
to use the name approxhnata when Allioni had formerly so named a 
Carex ? ” — Ar. Bennet. “ We quite agree with Mr. Bennett in 
rejecting Hoppe’s name for this plant. It is unfortunately a common 
practice when, as in the present instance, a name has been reduced 
to a synonym, to allow of its being used afresh for another species. 
This practice, however, besides causing needless confusion and being 
opposed to the main principle of the binominal system, presents a 
real obstacle to the attainment of finality in nomenclature. Suppose, 
for instance, we adopted the name “C. approximata^ Hoppe,” for this 
sedge, and it were subsequently found that two species had been con- 
founded under C. ericetorum, Poll., and that Allioni’s plant was 
distinct from Pollich’s, we should have no alternative but to restore 
the name of approximata to its rightful owner and look about for 
another name for our plant, which name might in its turn be similarly 
invalidated ; whereas we are on firm ground if we adhere to the rule 
that a name when once bestowed on a species (or genus) belongs 
inalienably to that species (or genus) and to no other.” — ^H. & J.

Carex Hudsonii, Ar. Benn. ; C. data, All. ; C. stricta, Good, {teste 
Kiikenthal, see ‘Journ. of Bot.,’ 1898, p. 274). Margin of stream,

C. aquatilis, Wahl., slender form. By the River Spey, below 
Kingussie, E. Inverness, 26th July 1898. — E. S. Marshall (2103). 
“ Herr Kiikenthal says that this is analogous to C. gradlis {acuta), var. 
personata, Fr., and suggests my giving it the name of forma gracilior, 
but I refrain from doing so, being doubtful whether there is any per- 
manent distinctness, although the living plant looked very peculiar.” —

C. aquatilis, Wahl., forma. By the Spey, below Kingussie, E. . 
Inverness, 26th July 1898, — E. S. Marshall. “‘Somewhat 
approaches var. epigeios, x\nders.,’ Kiikenthal in litt. A very marked 
form when growing, from its dwarf stiff habit, but I daresay that the 
drought of the summer had much to do with this.” — E. S. M. 
C. Goodenowii, J. Gay, vox. jujicella, T. M. Fries. Frimley, Surrey,

C. tomentosa, L, Far Hill, Fairford, Gloucestershire, 20th June 
1898. Coll. J. Taylor; comm. A. B. Jackson. Members will be 
glad to have specimens of this rare sedge. I suppose it is not in 
sufficient quantity to warrant the sending of roots. — J. G.
