FLOWERING TREES AND SHRUBS 23 



stem and branches are provided render the shrub of 

 rather formidable appearance, while the leaves are of a 

 peculiarly pleasing soft-green tint. For the flowers, too, 

 it is well worthy of attention, the pinky anthers contrasting 

 so markedly with the deep yellow of the other portions 

 of the flower. They are arranged in long racemes, and 

 show well above the foliage. 



Calluna (Ericaceae). See Erica. 



CALLUNA VULGABIS (syn Erica vulgaris). Common Ling 

 or Heather. This is the commonest native species, with 

 purplish-pink flowers on small pedicels. There are many 

 very distinct and beautiful-flowering forms, the following 

 being some of the best : C. vulgaris alba, white-flowered ; 

 C. vulgaris Hammondi, C. vulgaris minor, and C. vulgaris 

 pilosa, all white-flowered forms ; C. vulgaris Alportii, and 

 C. vulgaris Alportii variegata, the former bearing rich 

 crimson flowers, and the latter with distinctly variegated 

 foliage ; C. vulgaris argentea, and C. vulgaris aurea, with 

 silvery-variegated and golden foliage; C. vulgaris flore- 

 pleno, a most beautiful and free-growing variety, with 

 double flowers ; C. vulgaris Foxii, a dwarf plant that does 

 not flower freely ; and C. vulgaris purnila, and C. vulgaris 

 dumosa, which are of small cushion-like growth. They 

 succeed best in peaty loam. 

 



Calophaca (Leguminosae). 



CALOPHACA WOLGARICA. Siberia, 1786. This member 

 of the Pea family is of dwarf, branching growth, thickly 

 clothed with glandular hairs, and bears yellow flowers, 

 which are succeeded by reddish-purple pods, It is of no 

 special importance as an ornamental shrub, and is most 

 frequently seen grafted on the Laburnum, though its 

 natural easy habit of growth is far preferable. Hailing 

 from Siberia, it may be considered as fairly hardy at least.
