iirowing branches. The flowers are axillary, one on a pedicel ; the [lOtls are ob- 

 long-taper, and each contains 3 or 4 seeds. The wood is hard, compact, and very 

 tough ; yellow on the outside ; and within, waved and striped with red, and with 

 reddish brown. The bark is also very tough, and it is used as a substitute for 

 ropes or cords, as the twigs are for withs. The seeds are stated by Pallas to 

 be good food for poultry, and the leaves excellent fodder for cattle ; they are 

 also said to contain a blue colouring matter, like indigo. The species was 

 introduced into Britain in 1752, and is not uncommon in British collections. 

 The largest plant in the neighbourhood of London is at Syon, where it is 

 18 ft. high. In Ireland, in the (ilasnevin Botanic Garden, is one, 20 years 

 planted, which is 2+ ft. high; the diameter of the trunk, at 1 ft. from the 

 ground, is Tin., and of the head, which is roundish and compact, 12ft In 

 British nurseries, it is generally propagated by seeds, which are produced 

 freely. The price of plants, in the London nurseries, is 50s. a hundred, or 

 Is. each ; at BoUwyller, 50 cents each.

 (^Don\ Mill.y ii. p. 24-3.) A shrub, growing 

 to the height of 3 ft. or -i ft. in arid plains in 

 Siberia, and probably only a variety of C. arbo- 

 rescens. It was so considered by Pallas ; and 

 by others it has been confoundetl with C. iiii- 

 crophylla, also, as we think, only a variety. It 

 was introduced into England in 1789, and is 

 not uncommon in British collections. It is 

 usually propagated by grafting on C. arbo- 

 rescens. Price of plants, in the London nur- 

 series, 2s. 6d. each ; and at BoUwyller, 1 franc.

Spec. Char., t^c. Leaves with 6 — 7 pairs of hoary retuse leaflets. Petioles

 ii. p. 2i3.) A native of Siberia, and found in the desert of Baraba, and 

 in other arid places. It was introduced into England in 1819, and differs 

 very little from C. Altagana ; it, like that plant, being doubtless only a 

 variety of C. arborescens.

Spec. Char., Sfc. Leaves with two pairs of ovate, acute, smooth leaflets. 

 Stipules spinose. Flowers yellow. (Don^s Jllill., ii. p. 24-3.) A shrub, 

 of which there are several specimens in the Horticultural Society's 

 Garden, of the height of 4ft. or 5 ft. It is a native of Siberia; and the 

 plants referred to were raised from seeds received from Dr, Fischer of 

 Petersburg, about 1820. In general appearance and habit of growth, it 

 resembles C. Altagana, of which it is probably only a variety.
