ALPHABETICAL LIST OF PLANTS 255 



C. alpinum. — Dwarf-tufted plant, about 2 to 4 inches high. 

 Leaves ovate, lanceolate, densely covered with whitish down. 

 Large white flowers in early summer. Does not like excessive 

 moisture on its foliage, otherwise quite hardy. Increased by 

 division or cuttings inserted after flowering. 



C. Biebersteinii. — Silvery-white leaves, ovate, lanceolate, and small 

 white flowers in early summer. Grows 6 inches high. 



C. grandijiorum. — Very soon forms large tufts of hoary, narrow 

 leaves. Bears large pure white flowers in the greatest profusion in 

 the summer. Grows anywhere, and freely increased by cuttings or 

 by division. A well-known and showy plant for the rougher parts 

 of the rock garden, but too rampant in growth to put near anything 

 choice. 



C. tomentosum. — A form similar X.o grandiflorum^ but with smaller 

 flowers and more compact habit. 



The above are the only varieties of Cerastium worth growing 

 except in botanical collections, to which might be added glaciale^ 

 a large and handsome variety, and repens^ useful dwarf carpeter. 



Chamaebatia foliolosa (Rosaceae) 



A little-known, dwarf, evergreen, shrubby plant of the Rose family. 

 Pretty fern-like leaves and bramble-like flowers | inch across. 

 Quite hardy, and worth a spot in the less choicer parts of the rock 

 garden in light loam. 



Chamaelirium carolinianum (Liliaceae) 



Raised parts of the bog garden. A pretty plant with wand-like 

 spikes of white flowers. 



Chamaemelum caucasicum (syn. Matricaria) 



Dry position. Trailing habit, with fern-like leaves and white 

 flowers. Nearly allied to the Camomile family, and not of much 

 value. 



Cheiranthus (CRUCiFERiE), Wallflower 



Wallflowers are very useful for the wall garden. Besides the 

 well-known bedding varieties, there are a few of a rather distinct 

 habit. All are of the easiest culture. 



C. alpimis. — In old walls and dry banks. Forms neat little tufts 

 of dark green foliage, covered during the summer with a profusion 

 of small sulphur-coloured leaves. A very pretty little plant, of the 

 easiest culture, and well worth a spot in the rock garden.
