nyme of liyemale (Phytol. 338). The word “ Touvelle ” written by Linneus is 
probably a habitat.

Linneus. — S u ec . 
E. N. — A single specimen of Equisetum variegatiim of Smith, much more 
slender than the preceding : the Linnean MS. evidently implies the habitat, 
Sweden. 
I think the above notes will be sufficient to show that as regards several spe- 
cies of Equisetum, more especially the present, generally known as palustre, the 
Linnean herbarium is not a sure guide. There is, however, much collateral evi- 
dence that Linneus was not only acquainted with the Equisetum palustre of 
modern authors, but that he referred to that species when he named the plant 
in question ; for he expressed states that his fluviatile (Smith’s limosum) may be 
a variety of palustre growing in deeper water. Now as he was so well acquaint- 
ed with fluviatile (Smith’s limosum), and possessed such good specimens, his 
judgment cannot be supposed so much in fault as to have referred it to arvense. 
The error must have arisen from a want of care in the selection of specimens 
for his herbarium. Moreover, the name palustre is now too universally em- 
ployed to admit of its being changed, without a better reason than a discrepancy 
which may have originated in carelessness. The same is not the case with 
fluviatile : I am decidedly of opinion that the name, in this instance, must be 
changed ; and I make the proposition previously to publishing the species, in 
order that I may be favoured with the opinions of those botanists who think 
otherwise. I propose restoring the Linnean name to the limosum of Smith, and 
sinking the name limosum to the rank of a variety ; thus : — 
Equisetum fluviatile, Linn. = Equisetum limosum, Smith. 
„ „ /3. limosum, with the stem quite simple, = Equisetum 
limosum, Linn. 
The species hitherto called fluviatile is already so well provided with names 
that it is difficult to determine which to select. It seems to be the Equisetum 
majus of Gerarde^ and Ray,j' the Eq. Telmateia of EhrhartJ and Flora Dani- 
ca,§ and the Eq. eburneum of Roth.||
