After several unproductive searches for this rare, and not very conspicuous 
plant, on May-day 1827, the Editor had the pleasure to observe it growing- 
above the rocks within a few yards of the flag-staff on the sea-walls, 
Durdham Down. It is found imbedded on smooth patches of turf, and 
affects an eastern exposure. Of the station recorded by Hutchinson, 
Kirkland Fell pasture, Cumberland; Mr. Winch doubts the accuracy.
