CHYTROGLOSSA. 



Small-growing Brazilian plants, closely allied to 

 the Comparettias (vrd. Orchidacese), and succeed- 

 ing if similarly treated. Seldom seen in culti- 

 vation, but remarkably beautiful and interesting 

 miniature Orchids.

CIBOTIUM. 



The handsome tree Ferns known under this title 

 are now referred to Dicksonia, which see. 



CICER. 



Chick Pea plants (ord. Leguminoste), useful as 

 food producers, but of no horticultural or economic 

 value in this country. Half-hardy. Propagation 

 by seeds.

CIMICIFUGA. (BucnvoRT.) 



Effective hardy herbaceous border plants (ord. 

 Ranunculaceaa), which grow best in rather strong 

 soil with a little shade. They are propagated by 

 division in spring or autumn, or by seeds sown in 

 a frame when ripe or in spring.

CINCHONA. 



This genus (ord. Rubiacere) has immense value, 

 as it provides the celebrated quinine of commerce. 

 The plants are wholly indigenous to South America, 

 but their cultivation has been undertaken success- 

 fully in other parts of the world, especially in the 

 Government plantations in North India. They are 

 tall (4<Y to 5<y) evergreen trees and shrubs, that 

 require stove treatment and considerable care in 

 cultivation. They all have white or pinkish 

 flowers, which are fragrant. A compost of fibrous 

 peat, loam, and coarse sand is suitable. Prop-

CINERARIA. 



A large genus (ord. Composite), composed of 

 greenhouse evergreen shrubs and herbaceous 

 perennials, now referred by botanists to Senecio 

 Ihe phief interest is centred in the florists' 

 varieties, which have originated from cruenta 

 Several of the herbaceous species, including 

 maritima and its variety acanthifolia, are excellent 

 tor bedding purposes, (tee SENECIO). 



Description of Florists' Cineraria. Few green- 

 house plants are more attractive and useful than 

 Cinerarias, and the improvements made in the size 

 and colouring of the flowers have led to great 

 popularity. There are both single and double 

 varieties, but the former are most in favour. At 

 no time do Cinerarias require greater heat than 

 that of a greenhouse, and the cultivation, though 

 simple, must be thorough if the best results are to 

 be obtained. 



Propagation. From seeds sown in May for early 

 plants, and in June for succession. A shallow pan 

 is suitable, and it should be thoroughly drained 

 and filled to within 1" of the top with well- 

 prepared soil. Press the compost down level, 

 give a good watering through a fine rose, and, 

 after the moisture has drained away, scatter the 

 seeds thinly over the surface. Cover them with a 

 slight sprinkling of fine soil, place a square of glass 

 and a sheet of paper on the pan, and stand it in a 

 partially shaded position in a temperature of about 

 55". When the seedlings appear expose them to 

 the light, give air freely, and shade from hot sun- 

 shine, but avoid cold draughts. 



Soil. For seed pans use one part of loam and two 

 parts of leaf mould, with sufficient sand to keep the 

 compost open. Mix the whole together, and pass 

 it through a \" sieve. Use similar soil to the 

 above for small seedlings, but coarser in character. 

 For the final potting use equal parts of fibrous turf 

 and leaf mould, with a little well-decayed manure, 

 sand, and broken charcoal. 



Other Cultural Points. Cinerarias are often 

 transferred from the seed pans to small pots, but 

 a better method is to prick them off 2" or 3" 

 apart in small boxes. At this stage they 

 should be grown close to the glass in a cold frame, 

 preferably under the shade of a north wall. As 

 the plants fill up the intervening spaces in the box, 

 transfer them to 4" pots, and keep the frame close 

 for a few days, after which ventilation must be 

 freely provided. As Cinerarias are quick-growing 

 and free-rooting plants they should be removed to 

 larger pots before they get in a root-bound con- 

 dition. Plants may be flowered in 6" and 7" pots, 

 but 8" and 9" are better for fine specimens. Give 

 plenty of room after the final potting, and stand 

 the plants on inverted flower pots, placed on a bed 

 of sifted ashes in a frame. In all stages of growth 

 watering must be carefully attended to, avoiding 

 drought on the one hand, and a superabundance of 

 moisture on the other. A gentle dewing over the 

 foliage once a day with a syringe is beneficial in 

 hot weather, and the plants must be protected 

 from strong sunshine. Weak liquid manure, soot 

 water, and occasional top-dressings of an approved 

 fertiliser, may be given when the pots arc full of 

 roots. When frosts occur in the autumn remove 

 the plants to a pit or light house, having a tem- 

 perature of about 50, and a fairly moist atmo- 

 sphere. A bed of ashes on which to stand the 

 plants is preferable to a wooden stage. Air should
