On rocks in Canada and on the highest peaks of the Al- 
legany mountains, particularly at Grandfather-moun- 
tains, Carolina. 1 / . June, July. v. s. in Herb. Dick- 
son ; v. v. in Hortis. Flowers white. According to 
Willdenow, and the figure of P. retusa in the Flora 
Danica, which is quoted as a synonym, the flowers 
are yellow ; but this figure, if correct, presents most 
certainly a different plant, as the petals are round, and 
only the length of the calyx.
