as an undoubted native of Devonshire by Hudson, Stackhouse,
and other early writers on these plants. Hudson says of it, “ in
Devoniapassim,” and Stackhouse gives “ Devonshire and S.W.
coast ” as the station, but adds, “ This species is rare, and has
occasioned mistakes among om- English botanists, who, after the
example of Gmelin, have given it the trivial name of F.foeniculaceus,
which appears, by the Linnæan herbarium, to be a very different
species,” &c. Both these authors quote GmeliiTs figure, whicli.
Turner observes, “ is so characteristic ” of his F. barbatus “ as
to take away all doubts as to the species.” The last-named
author, however, adds, “ How far F. barbatus is really entitled
to a place in the British Flora I own I entertain much doubt. I
never saw a specimen gathered on our shores ; and in Devonshire,
where Hudson is stated to have gathered it, I have been
fortunate enough to enjoy the advantage of correspondents, who
would have been little likely to have left it unnoticed.” This
was written upwards of thirty years ago, since which time no
part of England has been more zealously or more successfully
explored (as these volumes bear ample evidence) than the coasts
of Devonshire and Cornwall, but no one has met with a scrap of
this plant ; wherefore I fear it is but too evident that it has no
claim to a place in this work.
