DiapensTa. Named by Linnaeus from diapente, com- 
posed of five; alluding to the flowers being five- 
cleft. Linn, b. Or. 1, Nat. Or. Diapensiacece. A 
very pretty little alpine plant, but rather difficult

from the severe dry frosts. It succeeds best grown 
in small pots, in peat soil, with the protection of a 
frame in winter. It is increased by seeds, or divi- 
sions.
