in the garden or border wherever a plant of their propor- 

 tions is desired. Most of them prove sufficiently hardy 

 to withstand our northern winters, and so adapt them- 

 selves to a large extent of country. So far as known 

 none of them is indigenous to America, though most of 

 them appear to be much at home among us. They are 

 all easily grown, and not especially particular as to soils 

 and situations. 



C. arborescens. This is a native of Siberia, and is the 

 species longest and best known in America, and under 

 favorable circumstances grows to a height of fifteen to 

 twenty feet. The foliage is compound, consisting of four 

 to six pairs of leaflets of good color which remain through 

 the season. The flow r ers are pale yellow, and very numer- 

 ous, so that when in blossom the little tree somewhat 

 resembles the viburnum. These appear in April or May. 

 There is a pendulous form of much smaller growth, and, 

 when height is desired, it can be grafted on taller stems 

 with good results, as the smaller branches fall gracefully 

 to the ground on every side. 



C. altagana is but a small shrub, two to four feet high, 

 with six to eight pairs of leaflets which are glabrous and 

 nearly round. Its blossoms are also yellow. C. chamlagu 

 is a native of China, and differs but little from the above 

 except that its flowers appear in June and are first golden 

 and then red. C. frutescens is another native of Siberia, 

 and has deep golden-yellow pea-shaped flowers in great 

 abundance, appearing in May and June. It is usually 

 two to four feet in height, and is one of the most valu- 

 able of its class. C. spinosa is also a Siberian plant,
