Charlock 



( 198) 



Cheiranthus 



CHARLOCK. 



A well-known native plant (Brassica Sinapistrura, 

 erd. Crucifera3). It is very nearly related to the 

 Mustard and Turnip, which relationship makes it a 

 source of danger in gardens where seeds of these, 

 or other Cruciferous plants, are saved from selected 

 stocks, as, should their period of flowering coincide 

 with that of the Charlock, some very undesirable 

 hybrids might be the result. In some rural districts 

 the young tops of the Charlock are cooked and 

 eaten as " greens." A solution of sulphate of copper 

 at the rate of 1 oz. per gallon of water has been 

 found useful for killing it.

CHEILANTHES 

 TENUIFOLIA. 



(ord. Filices) of over sixty species of very elegant 

 Ferns, distributed over temperate and tropical 

 regions. 



Propagation. By spores, which germinate 

 quickly and with considerable certainty if placed 

 amid consistently humid surroundings. 



Soil. Equal parts of fibrous loam and peat, with 

 sand, and a few pieces of charcoal and sandstone. 



Other Cultural Points. Cheilanthes are com- 

 monly regarded as being difficult to grow, and this 

 is so when placed amongst a general collection of 

 plants. Most of the species and varieties are 

 either woolly or covered with a fine powder, and 

 they detest having their fronds sprinkled with water. 

 They should be given a place on a shelf near the 

 glass in either the stove or greenhouse. Watering 

 must at all times be carefully performed, for if the 

 plants are allowed to become dry the pinnules curl 

 up and the fronds die, the death of the whole plant

usually following. Stagnant moisture is equally 

 fatal, and many a good plant is lost in winter in 

 this way. The pots should be half filled with 

 crocks. The most troublesome insect pests are 

 snowy fly and thrips. The remedy is slight 

 preventive fumigations with tobacco paper, or 

 vaporising. Slugs will also give trouble unless the 

 pots are stood upon crushed coke or sifted ashes, 

 over which the little pests do not care to crawl.

CHEIRANTHERA. 



These small shrubs (prd. Pittosporese) come from 

 New South Wales, and flourish best in well- 

 drained, light, rich loam and leaf mould, in the 

 greenhouse. They are easily increased from cut- 

 tings in sand or very sand}- soil, under a bell-glass. 



Principal Species : 



linearis, 4', Oct., bl. 



CHEIRANTHUS (.me also WALL- 

 FLOWER). 



Valuable perennial or biennial hardy or half- 

 hardy flowers (ord. Crucifene), best known from 

 Clieiri, the common Wallflower, in its varieties. 

 The species named are well adapted for the border, 

 rockery, or walls. Propagated by seeds sown in 

 the open or in cold frames ; or by cuttings in 



Cheimatobia Tirwmata (see A/y>le Enemies).
