Localities.— O n shady alpine rocks in Wales; very rar e.—MontgomerysJi. 
On the sides of a hill called Craig Wreidhin, or ralher Breiddin, where it was 
first found by Mr. Liiwvd ; see Ray’s Synopsis. It was for a long time sup- 
posed to have been lost; but on the 29ih of June, 1817, it was again found 
there, by J. E. Bowman, Esq. who observes, in the New Botanist's Guide, that 
“ this very local plant is distributed sometimes in groups very profusely, on the 
W. face ol the Breiddon Hill, occupying the middle zone, disappearing at 600 
or 700 feet of elevation, and also not descending near the base. It occurs again
