Diapensia. Named by Linnseus from diapente, 

 composed of iive ; alluding to the flowers being 

 five-cleft. Linn. 5, Or. 1, Nat. Or. Diapen- 

 siacece. A very pretty little alpine plant, but 

 rather difficult to cultivate, as too much mois-

 country, it is continually covered with snow in 

 winter, which protects it from the severe dry 

 frosts. It succeeds best grown in small pots, 

 in peat soil, with the protection of a frame in 

 winter, and is increased by seeds, or divisions. 

 See Pyxidaniliera.
