POLEMONIACEjE. III. PHLOX. 



Cull. The species of Diapensia are small, tufted, evergreen, 

 alpine plants, difficult of culture. They should be grown in 

 small pots, well-drained with sherds, in a mixture of sand and 

 peat, and placed among other alpine plants. They require to be 

 protected from frost and wet in winter, by placing them in a 

 frame. They may be increased by dividing at the roots.
