E. N. — A single specimen ofEq. hyeniale of Smith. The word or 

 abbreviation " CEdific." implying its uses, is written apart from the 

 name.

E. N. — A single specimen of Eq. variegatum of Smith. Linneus 

 answers the question as to its bein.j a distinct species, by giving basi- 

 liense asasynonyme of hyemale (Phytol. 338). The word "Tourelle" 

 written by Linneus is probably a habitat.

Linneus. — Suec. 



E. N. — A single specimen of Equisetum variegatum 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 species of Equisetum, more especially the present, generally 

 known as palustre, the Linnean herbarium is not a sure guide. There 

 is, however, much collateral evidence that Linneus was not only ac- 

 quainted with the Equisetum palustre of modern authors, but that ho 

 referred to that species when he named the plant in question ; for he 

 expressly states that his fluviatile (Smith's limosum) may be a variety 

 of palustre growing in deeper water. Now as he was so well ac- 

 quainted 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 arveuse. The eiTor must have arisen from a want 

 of care in the selection of specimens for his herbarium. Moreover, 

 the name palustre is now too universally employed to admit of its be- 

 ing changed, without a better reason than a discrepancy which may
