GUELDER ROSE. See Viburnum. 



GUERNSEY LILY. See Nerine Sarniensis. 



GUIZOTIA. [Compositoe.] Hardy annual. Cultivated 

 in Southern Europe as an oil plant. Soil, light rich 

 loam. Increased by seeds. G. oleifera is the only oue culti- 

 vated. 



GUM TREE. See Eucalyptus. 



GUZMANNIA. [BromeliaceaB.] A showy stove peren- 

 nial, allied to ^chmea and Vriesia. This jDlant has long 

 narrow leaves, from the centre of which grows an erect sj)ike, 

 terminated by broad overlapping bracts, which at the top are 

 scarlet, and below are green striped with brown, the flowers, 

 which the bracts almost conceal, being white. The treatment 

 recommended for ^chmea will suit this also. All the plants 

 of this race should have a period of repose answering to winter, 

 in which they should be kept comparatively dry and cool; 

 their growth is then much more vigorous when heat and 

 moisture are increased in spring, G. tricolor is one foot 

 high, and (lowers green, red, and white.

 })erennials, with pretty flowers. Soil, chalky loam. Increased

 curious than beautiful. 



GYMNOGRAMMA. [Polypodiacefe ] Beautiful ferns, 

 for the most part requiring stove temperature, and comprising 

 the species whose leaves, covered beneath with a white or a 

 yellow powdery matter, have obtained them the name of the 

 Gold and Silver Ferns. Soil, peat, loam, and sand. Increased 

 by division, or very readily by the spores or seeds scattei'ed 

 over a damp rough surface of peat earth. 



GYNERIUM ARGENTEUM. [Graminew ] Pampas 

 Grass. Highly ornamental, hardy, and of the easiest culture.
