Calceolaria 



(155) 



Calimeris 



by growing the plants in a cool, moist temperature. 

 A refreshing dew on the surface of the leaves in 

 the morning, while in the frame, wards off insect 

 pests and invigorates the plants. Watch for the 

 first traces of Aphis, and fumigate slightly. 



Varieties. --The finest flowers are continually 

 being crossed by raisers, with the result that the 

 best strains of mixed seed may be relied on to 

 produce flowers of wonderful brilliancy and diver- 

 sity of colour. 



Shrubby or Bedding Calceolaria. A few species 

 and a number of varieties and hybrids of the 

 shrubby Calceolaria are largely employed for 

 summer bedding. At one time masses of crimson 

 and rich brown flowers were to be seen, but now 

 the gulden yellow Calceolaria is the most popular. 



Propagation. Hybrids and varieties of rugosa 

 nre raised from seeds, which produce plants of a 

 wide range of colour. The best method of propa- 

 gating bedding Calceolarias is from cuttings in 

 the autumn. Early in October prepare a bed of 

 sandy soil in a cold frame, with a, thin layer of 

 sand on t he sin-face. Select young, growing shoots, 

 remove the lower leaves from them, and cut 

 horizontally just below a joint. Dibble them in 

 regularly and firmly, sprinkle with water through 

 a rose to'settle the soil and prevent flagging, and 

 keep the frame close and shaded for a few days. 

 The cuttings take a long time to root, but if air is 

 provided on favourable occasions, and protection 

 given in the case of severe frost, they will pass the 

 winter safely, and commence growth in the spring. 



Soil. A deep, loamy soil is necessary for Calceo- 

 larias if they are to flower well throughout the 

 season. They often die off in hot, sandy soils. 



Other Cultural Points. At no time do the plants 

 require artificial heat. When growth commences 

 in the- spring pinch out the points of the shoots to 

 encourage a branching habit. It is a great mis- 

 take to leave Calceolarias in the cutting frame till 

 more tender plants are bedded out in May or June. 

 The end of April is the best time for planting, but 

 if it cannot be done then the plants should be 

 transferred to temporary beds, made up of sandv 

 loam and leaf mould, and left there until they are 

 removed to their flowering quarters. Continual 

 blooming is encouraged by pinching off the old 

 llower stems. 



Diseases. Calceolarias are often disappointing 

 owing to their habit of dying off in the summer. 

 through a disease which causes the roots to 

 decay. There appears to be no direct cure, but 

 the trouble is most prevalent amongst plants., 

 growing in hot, shallow soils. Early planting is 

 the best preventive, because the plants become 

 firmly established before hot weather sets in. 



Select Varieties : 

 aurea floribunda, 1', yel.; Golden Gem, 1$', deep 



fine. yel. ; one of the best. 



Bijou, 1', dark red ; free. Prince of Orange, 1', or., 

 (iiiines's Yellow, 1', yel. ; br.; compact. 



good bedder. Sultan, 1' ; fine dark var. 



Species and Hybrids : 



Few of the pure species are used for bedding, 

 but amplexicaulis is useful for large beds and 

 bcmlers. It blooms late, and is about 1J' high ; its 

 lemon coloured flowers are very effective. The 

 hybrids of rugosa are of strong constitution, and 

 produce flowers of varied colours. 



Caicearia, (tee Corysanthes). 



CALDCLUVIA. 



The one species of this genus (ord. Saxifragese) 

 is a Chilian evergreen tree, requiring the protection 

 of a greenhouse, and may be propagated from 

 cuttings of half-ripe shoots inserted in sandy soil 

 in a warm, close case. Peat and loam form a 

 suitable compost. 



Only Species : 

 paniculata, 20', Je., wh. 



CALEA. 



A genus of herbs and sub-shrubs (ord. Com- 

 positai) largely distributed throughout tropical 

 America. The simple leaves have usually three 

 very distinct nerves and a rough surface. 



Principal Species: 



jamaicensis, 3', Je., pur. urticrefolia, 2', Jy., yel. 

 pinnatifida, Je., yel. 



CALEANA. 



A small terrestrial plant (nrd. Orchidacese) from 

 Australia, requiring greenhouse cultivation. The 

 flower is remarkable by reason of the irritability of 

 the lip. In fine weather it bends back, exposing 

 the column ; in wet weather, or when disturbed, 

 it closes up to protect the column. The plants are 

 cultivated in well drained pots in a compost of 

 fibrous peat and loam, with a little sandstone and 

 charcoal added. 



Principal Species : 



major, Je., grn., br. 



minor, Je., gru., br. 



CALECTASIA. 



A pretty Rush-like genus (ord. Juncacese) from 

 Australia, with a sub-shrubby habit and elegant,- 

 needle-shaped leaves sheathing the stem at the 

 base, and solitary, star-shaped, terminal flowers. 

 The stock can be increased by division, and a 

 mixture of sandy peat and loam makes a suitable 

 compost. Greenhouse cultivation is necessary. 



Only Species: 



cyanea, 1', Je., bl. 



CALENDULA. (MARIGOLD.) 



Effective plants (ord. Composites) for the garden 

 or greenhouse. The majority are annuals, but 

 there are a few of shrubby habit which must be 

 grown in the greenhouse. The latter should be 

 cultivated in loam" and leaf soil or peat ; the others 

 will grow in any good soil. The hardy annuals 

 can be sown in spring and treated as ordinary 

 hardy annuals ; the tender ones should be sown in 

 slight heat. The shrubby species are propagated 

 by cuttings in heat in spring. The best known is 

 ofticinalis, the common pot Marigold, of which the 

 varieties Meteor, Orange King, and Yellow Queen, 

 all with yellow flowers, are improvements. Others 

 are arvensis, 2', June, yellow ; maderensis, 2', 

 July, hardy annual, orange ; segyptiaca (syn. sicula), 

 1', June, hardy annual, yellow ; and suffruticosa, 

 1'. November, greenhouse shrub, yellow. (6'ee also 

 MARIGOLDS.) 



CALIMERIS. 



Hardy perennial plants (ord. Composite) now 

 included with the Asters, and requiring the same 

 treatment. That known as incisa (syn. Aster 

 incisus), which is about 3' high, flowers in July, 



Caldasia heterophylla (see lionplandia gemini- 



flora.) 

 Calico Hush (see Kalmia latifolia).
