 Johnston. Not native. Four plants only seen by me, and 

 these are now extinct, through the bank on which they 

 grew having been washed away hy the sea during a 

 severe storm, accompanied by an exceptionally high tide, 

 on 15th November 1920. Sepals pale whitish-blue, with

 gardens in Stromness, from which it has probably been 

 thrown out with weeds and rubbish.
