CYC 



velopmentofwood,as the Pelargonium, 

 Calceolaria, and Cineraria, will strike 

 in any place shaded from the meridian 

 sun. Cuttings of fleshy-leaved plants, 

 as the Cacti, and many others, root 

 better after being allowed to remain for 

 forty-eight hours, after division from 

 the parent plant, before they are plant- 

 ed. Diosmas, fuchsias, heaths, camel- 

 lias, &c., require for their cuttings the 

 gentle heat of a nearly exhausted hot- 

 bed, and a close atmosphere, with but 

 little light admitted night and morning. 

 The bell-glasses employed should be 

 proportioned to the size of the cutting. 

 A small cutting should no): be placed 

 under a large glass. Blue and violet- 

 coloured glass is found most favourable 

 for the purpose, and this is accounted 

 for by the fact, that glass of this colour 

 admits very few luminous or leaf- 

 stimulating rays of light; but nearly all 

 the chemical rays of the spectrum, 

 ■which assist in the decomposition of 

 bodies. M. Neumann has succeeded 

 in striking cuttings of monocotyle- 

 donous plants, such as Draycena,Frey- 

 cenettia, and Vanilla. The cuttings 

 may be from branches of any age be- 

 tween less than one and six years old. 

 They require to have the leaves cut 

 away at the bottom of tlie cutting, the 

 •whole, length of the portion to be buried. 

 It is not necessary to use the extremi- 

 ties of branches, pieces from their mid- 

 dles answer as well. M. Neumann also 

 thinks that all dicotyledonous plants 

 may be multiplied by cuttings of their 

 roots, or even by detached leaves. 

 Dais cotinifolia is increased from cut- 

 tings of the roots, and so is Faulownia 

 imperialis. Pieces two inches long, 

 and half an inch in diameter, and cut in 

 March, root well. Maclaura aurantiaca 

 succeeds similarly even in the open air, 

 the upper wound of the cutting being 

 placed nearly level with the surface. 

 He has also multiplied Araucaria Cun- 

 ninghami, and all the Coniferce, by root 

 cuttings. 



Soil. — The soil most generally appli- 

 cable, is that which is rich and light. 

 Some cuttings, as those of the Tamarix 

 elegans and T. germanica, require a 

 little saltpetre in the soil. 



CYAMOPSIS psoraloides. Hardy 

 annual. Seeds. Common soil. 



CYANELLA. Five species. Green- 

 house bulbous perennials. Offsets. 

 Sandy loam and peat. | 



CYANOTIS. Three species. Green- 

 house biennials. Seeds. Rich mould. 

 C. barbata is a hardy herbaceous peren- 

 nial. Increased by division. 



CYATHEA. Two species. Stove 

 evergreen ferns. Division or seeds. 

 Peat and loam. 



CYATHODES. Three species.

 tings. Peat and loam. 



CYCAS. Five species. Stove her- 

 baceous perennials. Suckers. Rich 

 loam. 



CYCLAMEN. Ten species, and 

 many varieties. Hardy or green-house 

 tuberous-rooted perennials. Seeds. 

 Sandy loam and vegetable mould. Spe- 

 cies most worthy of culture are — 



C. Coum. Round-leaved, spring- 

 flowering sowbread. Reddish purple. 

 January to March. 



C. Europceum. Round-leaved, sum- 

 mer-flowering sowbread. Reddish 

 purple. Fragrant. July to September.

 flowering sowbread. Like preceding. 

 November to January. 



C. Persicum. Persian sowbread. 

 Various colours. February to May. 



C. Neapolitanum. Neapolitan sow- 

 bread. Rosy. August to September. 



C. hederdfolium. Ivy-leaved sow- 

 bread. White and pink. Fragrant. 

 March to May. 



Mr. G. Gordon, of the Chiswick Gar- 

 dens, gives the following excellent 

 directions for their culture : — 



" The Cyclamen is increased by cut- 

 ting the largest roots in pieces, which 

 is a bad practice, as they are very liable 

 to rot during the first season after cut- 

 ting, or while in a dormant state, un- 

 less the parts are kept very dry, a 

 thing very injurious to the early flower- 

 ing kinds. 



"£!/ Seeds, which should be sown 

 when ripe, whether it be autumn or 

 spring, in pans or pots well drained, 

 and filled with a mixture of equal parts 

 of sandy loam and leaf-mould, to which 

 should be added a small portion of well- 

 rotted dung. Then place the pans or 

 pots in a cold frame or pit, kept close, 

 if sown in the spring ; but if sown in 

 the autumn, they should be placed on 

 the back shelf of the green-house, and 

 kept rather dry during the winter, and 

 gradually watered more as the spring 

 advances. 



" The autumn-sown plants will be fit
