the Mogul Tartars. The species are very hardy. 
1. C. arboréscens.—A shrub or small tree. Leaves com- 
posed of 8 to 10 oblong mucronate leaflets; common petiole 
deciduous, stipules scarcely spinescent. Flowers pale or bright 
‘yellow according to the variety, appearing in early Spring. A 
very desirable shrub on account of its extreme hardiness. 
C. sophorefolia is a form of this with smaller membranous 
leaves. A native of Siberia. 
2. CO. Aliagana, syn. C. microphglla.—oOf smaller stature 
than the foregoing, with smaller more numerous leaflets 
clothed with appressed hairs, and thorny stipules. The flowers, 
rather larger, are usually solitary. Also from Siberia, and 
flowering in Spring. 
3. C. Chamlagu.--A dwarf spreading shrub. Leaflets 
glabrous, mucronulate, in two distant pairs, the upper larger ; 
stipules mostly spinescent. Flowers solitary, dirty yellow, 
ultimately assuming a reddish tinge, appearing in June. 
A native of North China, where it bears the specific name. 
4. C. frutéscens.—Near the last, but of more ancient culti-

equal leaflets. Flowers solitary, yellow, on jointed peduncles. 
There are varieties under the names angustifolia, latifolia, 
&c., in cultivation. A native of Siberia, flowering in May. 
There is another group of species in which the common 
petiole is persistent and thorny. C. triflora and C. pjgmea 
are the species usually seen. The former has 6 or more 
pairs of leaflets and 2 or 3 flowers on a common peduncle; and 
the latter solitary flowers and 2 pairs of leaflets.
