Greenhouse and Stove Plants. 



193 



Cease syringing as the flowers begin to 

 open, and when they are fully gro-\vn move 

 to a greenhouse or elsewhere where they 

 will be cooler, with a drier atmosphere. 

 So treated the flowers will last fresh for 

 many weeks. The two forms, the red and 

 the white varieties, differ in nothing except 

 the colour of the flowers, requiring similar 

 treatment in every way. 



Insects. — Syringe to keep down red 

 spider. For aphides fumigate. 



GONIOPHLEBIUM 



A distinct and beautiful genus of Ferns, 

 comprising stove and greenhouse species, 

 many of them differing widely in size and 

 appearance. In the Javenese G. subauri- 

 culatum we have one of the most elegant 

 drooping Ferns in cultivation ; the pendant 

 fronds of a well-managed example of this 

 kind will reach 8 or 9 feet in length. 



For propagation and cultivation, see 

 Ferns, general details of culture.

GREVILLEA. 



The ornamental-leaved section of these 

 are pretty decorative plants, with finely 

 divided elegant Fern-like foliage. They 

 are well adapted for room or table decora- 

 tion, or for mixing with flowering plants 

 in greenhouses and conservatories. There 

 are large numbers of species in existence, 

 but only a few are considered worth 

 growing. Grevilleas are easily managed, 

 and quickly reach the most useful size for 

 general use, which is when from 15 to 24 

 inches high. They are easily raised from 

 seed, which should be sown about the 

 beginning of February in shallow pans 

 filled with fine sifted peat and sand ; sow 

 the seeds thinly and cover very lightly. 

 Stand in a temperature of 60°, keeping the 

 soil slightly moist, and as soon as the 

 plants are up keep them close to the glass. 

 In a few weeks they will be large enough 

 for putting singly into small pots, in soil of 

 a like description to that in which the 

 seeds were sown. Shade from bright sun, 

 and keep the atmosphere moderately moist ; 

 syringe overhead daily, and give air when 

 the weather will permit. The temperature 



should now be kept about the same in the 

 night as that in which the plants were 

 raised, and allowed to rise by day more or 

 less with the state of the weather. At the 

 end of May move into 6-inch pots, and 

 put a small stick to each plant to keep the 

 stem straight ; give air freely and keep 

 them well up to the glass, with a little 

 more shade as the sun gets more power ; 

 be careful never to let the soil get dry, or 

 the lower leaves will suffer, and the appear- 

 ance of the plants be spoilt. They will 

 grow fast and by the latter end of summer 

 will have reached a serviceable size, when 

 they can be used for any purpose for which 

 small handsome-foliaged plants are avail- 

 able. In winter locate them in a house or 

 pit where there is a temperature of about 

 45° in the night, with less water, but on no 

 account let the soil get dry. Such as are 

 kept on to attain a larger size must have 

 more pot-room in spring, and be given the 

 usual greenhouse treatment this summer. 

 After this they usually show a disposition 

 to lose their bottom leaves, which detracts 

 much from their appearance ; consequently 

 young stock should be grown on each 

 year. 



The two following kinds are most liked, 

 and will generally be found sufficient : — 



G. robiista. From Port Jackson. 



G. rosmarinifolia. From New South 

 Wales ; a pretty plant, but not equal to the 

 first-named. 



Insects. — Eed spider sometimes affects 

 Grevilleas, but can easily be kept down by 

 a free use of the syringe. For thrips or 

 aphides fumigate. 



GRIAS. 



These are evergreen trees requiring stove 

 heat. They grow to a large size, attaining 

 a height of 30 or 40 feet, and if to be seen 

 in anything approaching a fully-developed 

 condition they must have a very large 

 house, such as devoted to tropical j^lants. 



They are increased by cuttings of the 

 shoots which need a strong heat, and to be 

 subsequently grown on with stove warmth 

 until large enough to plant out, when they 

 should have a good-sized bed composed of 

 sandy loam. 



G. cauliflora. A large-growing species, 

 producing the fruit known under the 

 naine of Anchovy Pear. It is a native of 

 Jamaica. 



G. Fendlerii. A handsome-leaved species 

 that bears yellow flowers. Introduced 

 from Panama. 



G. zamorensis. Of this species little is 

 known as to what its appearance will be 

 when fully grown in a cultivated state,
