DESCRIPTIVE AND SELECTIVE. 231 



GALAX APHYLLA {Blandfordia Cordata.)— 

 A pretty plant growing three to six inches high and 

 bearing white flowers in July. The leaves are used in 

 floral decorations. It is a North American perennial 

 evergreen, of tufty habit, and easily propagated by 

 division in autumn. It does best in leaf mould, loam 

 and grit. 



GA ULTHERIA PROCUMBENS (Creeping 

 Winter-green or Partridge Berry). — A creeping 

 evergreen shrub, which bears white flowers in July, 

 and red berries as large as peas throughout the winter. 

 The oil expressed from the latter is used by perfumers. 

 It is a North American plant of tufty habit. It likes 

 moist peat, and is apt to die out on light dry soil. It 

 may be propagated by seeds or layers. 



GENISTA (Rock Broom). — ^The Genistas are often 

 confused with the Cytisuses, C. racemosus, for example, 

 the neat, dwarf, yellow-flowered shrub so much used 

 for greenhouses, is often called G. racemosa. They 

 are particularly useful for hot, dry, sandy soils, 

 where many plants will not thrive ; but they can, 

 of course, be grown on better ground. They do not 

 care for damp clay soil. Propagation may be effected 

 by seeds or cuttings under glass in spring. His- 

 panica, with yellow flowers in June ; and its dwarfer 

 variety nana, are as good as any for the purpose 

 in view. Tinctoria, which bears yellow flowers in 

 early summer, is also suitable. There is a double 

 variety. Elatior is a tall, Caucasian form of 

 tinctoria.
