 they are well adaj.ted for borders of evergreen shrub- 

 beries as well as for rockeries, and in suitable soil they 

 are apt to form a handsome evergreen ground-cover. 

 Most of the foreign species can be grown only South or 

 as greenhouse shrubs. Some have edible fruits, and an 

 aromatic oil used in perfumery and medicine is ob- 

 tained from G. procumbens and several Asiatic species. 

 They grow best in sandy or peaty, somewhat moist soil 

 and partly shaded situations. Prop, by seeds, layers or 

 suckers, division of older plants, and also by cuttings of 

 half-ripened wood under glass. About 90 species in the
