growing branches. The flowers are axillary, one on a pedicel; the pods are ob- 
long-taper, and each contains 3 or 4seeds. 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 Glasnevin Botanic Garden, is one, 20 years 
planted, which is 24ft. high; the diameter of the trunk, at 1 ft. from the 
ground, is 7in., and of the head, which is roundish and compact, 12 ft. 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 
1s. each; at Bollwyller, 50 cents each.

Derivation. Altagana is the name of the shrub in Siberia, 
Engravings. Pall. Fl. Ross., t. 42., under the name of Robinia Altagana ; L’Heérit. Stirp., t. 76. ; 
and our fig. 308. 
Spec. Char., §c. eaves having 6 or 8 pairs of 
glabrous, obovate-roundish, retuse leaflets. 
Petiole unarmed. Stipules spinescent. Pe- 
dicels solitary. Legumes rather compressed. 
(Don’s Mill, 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- 
réscens. It was so considered by Pallas; and 
by others it has been confounded with C. mi- 
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- 
réscens. Price of plants, in the London nur- 
series, 2s. 6d. each ; and at Bollwyller, 1 franc.

Spec. Char., §c. Leaves with 6—7 pairs of hoary retuse leaflets. Petioles 
and stipules rather spinescent at the apex. Root creeping. (Dons 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. Altagdna; it, like that plant, being doubtless only a 
variety of C. arboréscens.

Identification. Dec. Légum., t. 11.; Don’s Mill, 2. p, 243, 
Engraving. Dec. Légum., t. 11., f. 45. 
Spec. Char., §c. 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 4 ft. or 5ft. 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. A/tagana, of which it is probably only a variety.
