CUT 



CUSSO'NIA. (Named after P. Cusson, 

 ft French botanist. Nat. ord., Ivyworts 

 [Araliacese]. Linn., 5-Pcntandria 2-Di- 

 $ynia. Allied to Panax.) 



Greenhouse evergreen shrubs from the Cape of 

 Good Hope, with green flowers ; cuttings in sand, 

 under a glass, with bottom-heat ; loam and peat. 

 C. spica'ta (spike-./Zozc^mZ,). 6. 1789- 



thrysijtu'ra (thyrse-ttowered). 6. 1795 



tri'pteris (three-winged). 4. 1816. 

 CUSTARD APPLE. Ano'na. 



CuTTiNa is a part of a plant capable 

 of emitting roots, and of becoming an 

 individual similar to its parent. The 

 ircumstanoea requisite to effect this are 

 a suitable temperature and degree of 

 moisture 



A rooted cutting is not a new plant ; 

 it is only an extension of the parent, 

 gifted with precisely the same habits, 

 and delighting in exactly the same de- 

 gree of heat, light, and moisture, and in 

 the same food. There are numbers of 

 plants which strike most readily from 

 the young shoots ; others from partially- 

 ripened wood ; some from a leaf with a 

 bud at its base ; a fourth set from off- 

 shoots from the base of the old plants; 

 and a fifth from leaves or portions of 

 leaves only ; and in some rare cases, 

 from the mere scolloped edges of the 

 leaves; whilst several can only, be pro- 

 pagated by cuttings of the roots, and a 

 few by cuttings of the flower-stems. 

 Particular cases will be described tinder 

 the names of the species requiring some 

 peculiar mode. In this place only gene- 

 ral hints can be given. 



Cuttings of hardy floivt ring-plants. 

 Most kinds of quick- growing, soft-Avood- 

 ed plants are best propagated by the 

 young shoots or tops of the plants. 

 The following list embraces the prin- 

 cipal of them : Soft-icooded plants. 

 Auagallis, Antirrhinums, Calceolarias, 

 Carnations, Chrysanthemums, Dahlias, 

 Dinathus, Double Wallflowers, Double 

 Stocks, Gorterias, Gaillardias, Dwarf Lo- 

 belias, Fuchsias, Pelargonium, Petu- 

 nias, Penstemons, Pinks, Salvias, and 

 Verbenas. These may all be placed in 

 pots, in sand, in a frame heated either by 

 leaves, manure, or tan, or in a pit or 

 house built purposely, and heated by a 

 tank and hot-water pipes. Greenhouse 

 hard wooded plants or shrubs that strike 

 best from young shoots or tops : Aca- 

 cias, Aphelexis, Azalea (Chinese), Bo- 

 ronia, Bossisea, Chironia, Chorozema, 

 Crowea, Correa, Cytissus, Daviesia, Dil-

wynia, Epacris, Eriostemon bnxifoliura 

 (for stocks to graft the other species 

 on), Erica, Gastrolobium, Gompho- 

 lobium, Hardenbergia, Leschenaultia, 

 Kennedy a, Mirbeiia, Oxylobium. Platy- 

 lobiura, Pleroma, Podolobium, Pimelia 

 decussata (for stocks to graft the rest o 

 the genus upon), Pultensea, Styphelia,, 

 Tacsonia, Zichya, and all New Holland 

 shrubs of similar habit. These require 

 to be placed in a gentle tan-bed, planted 

 in pots, in silver sand, closely covered 

 with bell-glasses, which should be wiped 

 dry occasionally, and shaded from clear, 

 bright sunshine. Great numbers of stove 

 plants of woody habit require the same 

 mode of treating their cuttings, for which 

 see the body of the Dictionary. 



Cuttings of partially -ripened Wood. 

 Camellia, Cape Pelargoniums, Conifers, 

 Erythrina, Echites, Gardenia, Gordonia, 

 Hakea, Magnolia, Metrosideros, Neiium, 

 Portlandia, Kosa, especially the China 

 and Tea-scented, and most kinds of hardy 

 evergreen shrubs. 



Cuttings of Leaves loith a Bud at the 

 Base. When cuttings of any kind of 

 large-leaved plants are scarce, they may 

 be successfully increased by single leaves 

 with a bud at the base. We need not 

 particularize any species, as most of the 

 last section, and several of the others 

 that have moderate-sized leaves, may be 

 propagated in this mode of making cut- 

 tings. 



Cuttings' of Leaves only, without Buds. 

 The following will increase readily by 

 this mode : Achimenes, Gesnera, Glox- 

 inia, and all of similar habit, as well as 

 some Begonias. 



Cuttings of Offshoots from the base of. 

 the old plants. Cinerarias, tall Lobelias, 

 Statices, and most kinds of herbaceous 

 plants, increase readily by this mode. 



Cuttings of the Roots. There are a 

 few plants that will not readily increase 

 by any of the above modes, particularly 

 some herbaceous plants: (Enothera ma- 

 crocarpa is one, and CEnothera cjsspitosa 

 is another. Amongst hardy shrubs the 

 Pyrus Japonica and its varieties will 

 propagate by this mode ; also the Abelo 

 poplar. In the stove, the Ardisias, Cle- 

 rodendrums, Dracsenas, Ipomseas (the 

 tuberous-rooted species), and the Petrcea 

 Stapelia. 



Cuttings of the Flower-stem. Double 

 white and yellow Kockets, the tall Lobe- 

 lias, Double Lychnis, and a few others,
