Cyananthus 



( 263 ) 



Cyathea 



Geraniums, Poinsettias, etc., by cuttings formed 

 from portions of the stem after the growing point 

 has been removed. The usual practice is to wait 

 for back buds to break after the growing point of a 

 shoot has been removed; they are then made into 

 cuttings. There is no real need for this, as, where 

 the shoot can be spared, it may be severed almost 

 at its base, and every portion containing two or 

 three eyes utilised as a cutting. 



Bottom heat, especially that furnished by a hot- 

 bed, greatly facilitates the emission of roots in soft- 

 wooded plants; for hard-wooded plants it is not 

 recommended to be used until the cuttings have 

 formed a callus at their base in a cool house or 

 pit, when they quickly send forth roots on the 

 application of a little bottom heat. 



Propagation by means of leaf cuttings is readily 

 effected in the case of such plants as Id-x 1;,-. 

 goni;is, Gesneras, Gloxinias, and Saintpaulias. 

 The process consists of making a notch in the 

 midrib, and bringing this into contact with a bed 

 of light, sandy soil ; or by inserting the leaf by its 

 base, near the edge of a pot, in the manner prac- 

 tised with stem cuttings. 



-Many plants may be propagated by means of 

 root cuttings, which are cut into lengths varying 

 from 1" to IV, and placed 1" or so below the 

 surface of pans of sandy soil. A few of the plants 

 lending themselves to this manner of propagation 

 are Acalyphas, Aralias, Bouvardias, Dracaenas, 

 Clematises, 1'assifloras, and Hellebores. 



Eyes, consisting of a small portion of the stem, 

 with one leaf and an axillary bud, are used as 

 cuttings in some instances ; mostly in the prop- 

 agat.on of the Vine, though Dracienas and Dieit'en- 

 bachias are also increased in this manner. 



Cuttings of fruit trees, such as Gooseberries 

 and Currants, are best inserted in October and 

 November ; using shoots of the current year, 

 detached if possible with a heel, and inserting 

 firmly on a border having a northern aspect. 



CYANANTHUS. 



A genus of about eight species of hardy herb- 

 aceous plants (nrd. C'ampanulaccic), of consider- 

 able beauty, and much prized for rock gardens. 

 They thrive in a sunny position in light, moist, 

 sandy peat. A mulch of about 1" of sand during 

 winter is beneficial. They are propagated by 

 seeds and cuttings, the former sown in pots in a 

 frame in spring, and the latter made from the 

 young growths, also in spring. 



Principal Species : 

 ineanus, 4", Aug., light bl. lobatus, 4", Aug., pur. bl. 



Other Species : 



barhatus. intlatus. microphyllus. 



Hookeri. integer. pedunculatus. 



CYANELLA. 



Pretty little bulbous plants, generally included 

 in the ard. Liliaccir, but classed with the Ha-mo- 

 doraceai in the Index Ai'im/*;.*. They are almost 

 hardy, and may be treated like the Ixia, or groun 

 in a frame like many other of the smaller Cape 

 bullis. Increased by seeds and offsets. 



Principal Species : 



alba, 1', Jy., wh. lineata, odoratissima, 



capensis, 1', Jy., bl. and rosea. 



lutea, 1', Jy., yel., vurs. orchidiformis, 1', Aug.,bl. 



CYANOPHYLLUM. 



A genus (/v/. .\lel.-istomacea?) now merged in 

 Miconia. They are soft - wooded, ornamental 



foliage shrubs requiring stove heat. They are 

 propagated by means of cuttings placed in sandy 

 soil in a warm case, and grow readily in a 

 mixture of fibrous peat and loam, with a" liberal 

 addition of silver sand. (For fuller description 

 and list of species, see MICOXIA.) 



CYANOTIS. 



Tradescantia-like herbs (onl. Commelinacese), 

 from 1" or 2" to 1' or more in height, with 

 fleshy steins and leaves, and crowded heads o 

 blue, purple, or rose Mowers, from South Africa, 

 India, etc. They root quickly from cuttings, and 

 grow in an intermediate temperature in well-

drained soil in pans or borders. They should be 

 replanted every spring.

CYATHEA. 



Evergreen tree Ferns (trrtl. Filices), suitable for 

 stove or greenhouse, from tiopical and jub-trqpical 

 regions. The numerous species vary greatly in 

 habit, some making short, thin stems, 2' to 3' high, 

 witli fronds the same length ; others stout steins 

 15' to 20' in height, with fronds upwards of l.V 

 long and t' wide. The fronds of some form wide- 

 spreading, flattened heads, as in Dick.-onia. and, 

 like many of that genus, are produced, a large 

 number at a time, once a ve;ir. Ot tiers, as in 

 medullaris, produce upright fronds three or six 

 together two or three time- .-t \ear. The growth 

 in height of some, species is very slow, yvhilst
