530 ARBORETUM AND FKUTICETUM. PART III. 



growing branches. The flowers are axillary, one on a pedicel; the pods are ob- 

 long-taper, and each contains ;> 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 tor withs. The seeds are stated by Pallas to 

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

 also saiil 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 

 l> t't. high. In Ireland, in the Glasnevin Botanic Garden, is one, 20 years 

 planted, which is 24- ft. high; the diameter of the trunk, at 1 ft. from the 

 nound, 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 Boll wy Her, 50 cents each.

 Derivation. Altagana is the name of the shrub in Siberia. 

 Engravings. Pall. Fl. Ross., t. 42., under the name of Robing Altagana ; L'Herit. Stirp., t. 76. ; 



and our Jig. 308. 



Spec. Char., $c. Leaves having 6 or 8 pairs of 

 glabrous, obovate-roundish, retuse leaflets. 

 Petiole unarmed. Stipules spinescent. Pe- 

 dicels solitary. Legumes rather compressed. 

 (Dun's Mi/L, ii. p. 243.) A shrub, growing 

 to the height of 3 ft. or 4 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 confounded with C. mi- 

 crophylla, also, as we think, only a variet}'. 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 Bollwyller, 1 franc.

Pea Tree.

Spec. Char., fyc. Leaves with 6 — 7 pairs of hoary retuse leaflets. Petioles 

 and stipules rather spinescent at the apex. Root creeping. (Don's Mill., 

 ii. p. 243.) 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., tfc. Leaves with two pairs of ovate, acute, smooth leaflets. 

 Stipules spinose. Flowers yellow. (Don's Mill., ii. p. 243.) A shrub, 

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

 Garden, of the height of 1 ft. or 5 ft. It is a native of Siberia; and the 

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

 PetCTfburg, about 1820. In genera) appearance and habit of growth, it 

 retenbli i C. d&agdna, <>( which it is probably only a variety.
