The flowers are golden yellow, rather large, and borne 

 in clusters in the axils of the leaves. It is admirably 

 adapted for planting on dry, warm ledges in the rock 

 garden, and produces a rich colour effect during April 

 and May. C. keivense, a hybrid between the two fore- 

 going species, and its decumbent habit renders it of 

 special value for planting on banks and on broad ledges 

 in the rock garden. The flowers are produced in April 

 and May, and are large in size and of a pleasing shade 

 of primrose yellow. C. prxcox, a charming species of 

 slender growth, and forming a dense bush. The flowers

 useful for banks and on the rockery ; the flowers are 

 large and of a rich purple hue. C. purpureus albus, white ; 

 and C. purpureus ratisbonensis, yellow, are desirable forms.

 dndreanus, is the best for the garden. The flowers 

 have a yellow keel and crimson wings, a very effective

 place in the smallest garden. They are of moderate 

 growth, and appear to the greatest advantage when

 The few that will be mentioned as the most desirable

 cuttings, and the best time for layering the shoots 

 or taking cuttings is early in the autumn, when the
