CALOPHACA WOLGARICA, Fischer. LEGUMINOS^. 



A deciduous shrub, said to become 6 ft. high, but rarely more than 

 half as high in this country: bark of branches downy when quite young, 

 peeling when old. Leaves pinnate, 2 to 3 ins. long, composed of eleven 

 to seventeen leaflets. Leaflets oval to orbicular, \ to \ in. long, the 

 main-stalk of the leaf and the under-surface of the leaflets covered with 

 down. Racemes produced from the leaf-axils of the current year's 

 growth, 3 to 5 ins. long, very downy, carrying four to nine flowers 

 towards the end. Flowers yellow, pea-shaped, f to i in. long, each on 

 a stalk \ in. long ; calyx downy, \ in. long, with slender pointed teeth. 

 Pod f to 1 1 ins. long, cylindrical, covered with glandular hairs, one- or 

 two-seeded. Blossoms in June and July. 



Natives of the south-eastern part of European Russia, in the regions 

 of the rivers Volga (from which it take its name) and Don. It is 

 frequently found in arid places and on dry hillsides. Introduced in 

 1756. It is quite hardy in the south of England, but may need the 

 protection of a wall in the north. It likes abundant sunshine, and 

 during hot summers flowers profusely. It is only after such seasons that 

 seeds ripen. As a rule it is grafted on standards of laburnum or Caragana, 

 when it forms a big, mop-headed plant with semi-pendent branches. Plants 

 raised in that way are sometimes short-lived, but it is probably the best and 

 easiest way, for plants raised from seed are not easy to rear. They are 

 very liable to decay through damp during the winter, and should for two 

 years be kept in pots, then planted out on a well-drained site. When 

 grafted on the laburnum, no special precautions are needed. 



CALYCANTHUS. CALYCANTHACE^:.

 previous year's growth. Sepals and petals numerous. Fruits hard, and 

 shaped like a small fig, retaining the seeds for a long time. From the
