50 Flora of Devon mid Cornwall, by I. W. N. Keys. 
is figured in bis W. D. d C. Fl, and the following habitat is 
therein cited:—" To tbe left, at the end of Longbridge, leading 
to Bickleigh vale. C.A.Johns, Esq., most rare." It has, how- 
ever, long since disappeared from that locality, and, so far as I 
am aware, is not known to occur elsewhere in Great Britain. 
Blue Woodruff.] 
Dr. Jacob did not concur in the opinion that this species was introduced. 
He says, in the work quoted, — "This very interesting plant was first dis- 
covered in the habitat above-mentioned, in 1830, in a spot near where the 
rail-road l has been made, by C. A. Johns, Esq., F.L.S., from whom I 
received my specimens. There can be no doubt, I should imagine, of the 
habitat being truly wild, and it is not improbable that the formation of the 
rail-road above-mentioned might be the cause of its appearance, by bring- 
ing the seeds within the power of vegetation. It was certainly known to 
Gerarde, whose plate of it is extremely good. It grew, according to him, 
" in many places of Essex, and divers other parts in sandy grounds." 
By the side of Dr. Jacob's opinion place that of Mr. Hewitt Cottrell 
Watson, who says of this species (Cyb. Brit. ii. 23) that it is " scarce 
deserving to be kept among English plants, even as an introduced species ; 
its localities appearing to be transitory and uncertain." " Who shall 
decide when doctors disagree ? "
