1 To this species of Saxifraga, L,., unknown to our Flora (Gerard, p. 528), 
our author, with little doubt, referred the pretty 5. Virginicnsis, Michx. — See p. 
58 of this, note. 
2 Gerard, em., p. 535, — Salicornia herbacea, L. But Linnaeus referred one of 
Clayton's Virginia specimens (the rest he did not distinguish from 5. herbacea) 
to a variety, /3. Virginica (which he took to be also European ; Sp. PL'), 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 1 . mucronata, Bigel. (PL Post., edit. 2, p. 2), which may 
perhaps best be taken for a peculiar variety (S. herbacca, ft. mucrouata, articu- 
lorum dentibus squamisque mucronatis, Enum. PL Ca?itab., Ms. ; and 5 1 . Vir- 
ginica may well be another) of a species common to us and Europe. It is certain 
that we have plants stridtly 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. " Linnaaus ut Tournefortii errores corrigeret, varietates nimis con- 
traxit." — Link, Phil. Bot., p. 222. 
8 Hypericum perforatum, L. ("Hypericum, S. fohn's-ivort ; 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 //. 
corymbosum, Muhl., in his mind. 
4 Hypericum quadranguluni, L. (Gerard, p. 542) ; for which our author doubt- 
less mistook //. mutilum, L. (//. parviftorum, Willd.), a species peculiar to 
America; to which Cutler's H. quadrangulum (Account of Indig. Veg., /. c, p. 
474) is probably also to be referred.
