GLENNYS HANDBOOK 



GORDONIA. [Ternstroiniaceae.j Fine deciduous shrubs, 

 which are nearly hardv, requiring peat soil, and a damp but 

 sheltered situation. G. lasianthus is a suitable plant for a 

 cold conservatory. G. Javanica requires a warm greenhouse. 

 Increased by cuttings of the young shoots in sand under a 

 bell-glass. G. pubescens is a favourite. 



GOSSYPIUM. Cotton Tree. [Malvaceee.] Stove plants. 

 The common Cotton tree, G. herhaceum, is a stove annual, 

 requiring similar treatment to the Balsam. 



GRAMMANTHES. [Crassulace^.] Pretty little green- 

 house annuals. Sandy loam, finely broken chai'coal, and leaf- 

 mould, equal parts, will be a proper soil. Sow thinly in five- 

 inch pots, in which they are to flower, being thinned out 

 moderately if they come up too near each other. 



GPiAMMITIS. rPolypodiacese.] Interesting simple-leaved 

 dwarf ferns. Soil, peat and loam. Increased by division. 

 They are mostly tropical plants. 



GRAPE HYACINTH. See Muscari. 



GREEK VALERIAN. See Polemonium. 



GREVILLEA. [Proteacese.] A large genus of green- 

 house shrubs, most of the species interesting evergreens, but 

 not possessing a gaudy character. They are increased by 

 cuttings planted in sand, and placed under bell-glas.ses on a 

 shady shelf in a greenhouse, or in a frame. The plants should 

 be grown in equal parts loam and peat earth of a turfy tex- 

 ture, the compost being made rather sandy for the younger 

 ones, which are to be at first potted into small pots, and 

 shifted into larger ones only when they become pretty well 

 filled with roots. The plants should have the tips of the 

 young shoots removed when an inch or two long, until they 

 have acquired some size, under which treatment they will be 

 bushy and well furnished with branches quite down to the 

 pots. The flowers are of very curious struciure. 



GRIFFIXIA. [Amaryhidacese.] Pretty stove bulbs. 

 The gentral treatment should be that given to the stove 

 species of xAmaryllis. Soil, peat, loam, leaf-mould, and sand. 

 Propagated by offsets. G. hyacinthina, one foot high, is good. 



GRIXDELIA. [Compositae.] Greenhouse or half-hardy 

 plants. Soil, peat and loam. Increased, the sub-shrubby 

 kinds by cuttings, the others by division or by seeds.
