1 To this species of Saxifraga, L., unknown to our Flora (Gerard, p. 52S), 

 our author, with little doubt, referred the pretty 5. Virginiensis, Michx. — See p. 

 5S of this, note. 



- Gerard, em., p. 535, — Salicornia Jierbacea, L. But Linnaeus referred one of 

 Clayton's Virginia specimens (the rest he did not distinguish from 5. herbacea) 

 to a variety, 0. Virginica (which he took to be also European; Sp. PI.'), and 

 afterwards raised this to a species, as 5. Virginica, Syst. Nat., vol. ii. p. 52, 

 Willd. Sp. PL, vol. i. p. 25. To this the more common glasswort of our salt 

 marshes is to be referred ; and we possess, beside, a still better representative of 

 the European plant in 5. mucronaia, Bigel. {FL Bost., edit. 2, p. 2), which may 

 perhaps best be taken for a peculiar variety (S. herbacea, fi. mucronaia, articu- 

 lorum dentibus squamisque mucronatis, Ennm. PL Cantab., Ms. ; and 5. Vir- 

 ginica may well be another) of a species common to us and Europe. It is certain 

 that we have plants strictly common to American and European Floras, in which 

 the differences referable to difference of atmospheric and other like conditions are 

 either not apparent or of no account; and it is possible that there are yet other 

 species, now considered peculiar to America, which only differ from older Eu- 

 ropean species in those characters — whether of exuberance mostly, or also of 

 impoverishment — in which an American variety of a plant, common to America 

 and Europe, might beforehand be expected to differ from an European state of 

 the same. " Linnaeus ut Tournefortii errores corrigeret, varietates nimis con- 

 traxit." — Link, Phil. Bot., p. 222. 



3 Hypericum perforatum, L. {"Hypericum, S. John's-iuort ; in shops, Perfo- 

 rata." — Gerard, edit, cit., p. 539). The species is considered to have been in- 

 troduced, by most American authors; and it is possible that Josselyn had H. 

 corymbosum, Muhl., in his mind. 



4 Hypericum quadrangulum, L. (Gerard, p. 542) ; for which our author doubt- 

 less mistook H. mutilum, L. (H. parviflorum, Willd.), a species peculiar to 

 America; to which Cutler's H. quadrangulum (Account of Indig. Veg., L c, p. 

 474) is probably also to be referred.
