HALIMODE’NDRON Fisch. Tur HaLtimopenprRon, or SALT TREE. 
Lin. Syst. Diadélphia Decandria. 
Identification. Fisch. in Litt.; Dec. Légum. Mém., 6. ; Prod., 2. p. 269. ; Don’s Mill., 2. p. 244. 
Synonyme. Halodendron Dec. Mém. ined. in Soc. Phys. Gen., March, 1824, but not of Petit Thouars. 
Derivation. Fom halimos, maritime, and dendron, a tree; in reference to the habitat of the shrubs, 
which grow in dry naked salt fields by the river Irtis, in Siberia, 
Description, §c. Deciduous shrubs, with silky leaves, and purplish flowers. 
There are only two species, ‘one of which is probably only a variety. They 
are propagated by seeds, by cuttings of the roots, or by grafting on the common 
laburnum, or on the Caragdna arboréscens. 
% 1. H.arGe’nteEum Dec. The silvery-/eaved Halimodendron, or 
Salt Tree. 
Identification. Dec. Prod., 2. p. 269.; Don’s Mill., 2. p. 244. 
Synonymes. Robina Halodéndron Lin. Fil. Suppl., 330., Pall. Fl. Ross., t. 36.; Caragana argéntea 
Lam. in Pall. Itin. ed. Gall., App. ii. 360, t. 83. f. 1. 
Engravings. Pall. FI, Ross., t. 36.; and our fig. 315. 
Spec. Char., §c. Leaves hoary. Peduncles 2-flowered. (Don’s Mill., ii. 
p. 244.) 
Varieties. De Candolle mentions two forms of this species. 
% H. a. 1 vulgare Dec. Prod., ii. p. 269. — Leaves hoary or silvery. 
Standard the same length as the keel. (Sims Bot. Mag., t. 1016.) 
2 H, a. 2 brachyséma Dec. Prod. ii. p. 269.— Leaves hoary or silvery. 
Standard one half shorter than the wings and keel. Style short. 
Description, §c. An irregular, much branched, rigid 
shrub, with a strigose grey bark, and leaves clothed with 
a whitish silky down. The flowers are numerous, re- 
sembling those of Lathyrus tuberdsus, both in colour and 
size; and they smell sweet. It is a native of Siberia, in 
saline steppes, near the river Irtis; and, according to 
Pallas, it is much frequented by insects, especially of the (7, 
genus Méloe L., many species of which are peculiar to (| vi 



that region. It was introduced into Britain in 1779, by QcWy 
Dr. Pitcairn ; and, according to Martyn’s Miller, though “SS 
it flourished in British gardens, it seldom, if ever, flowered rs : 
there, “ probably for want of the saline principle in the soil.” It has 
been argued by some, that the halimodendren, and other trees which grow 
naturally in saline soils, should be supplied with sea salt in a state of culture : 
but, though this may be useful in some cases, experience proves that it is alto- 
gether unnecessary in others; and this is confirmed by the success with which 
the species before us is cultivated in British gardens. At present, it flowers freely 
from May to July, and, in moist seasons, later; and, when grafted standard high 
on the common laburnum, it forms one of the most graceful drooping trees that 
can adorn a lawn. There is a fine specimen of this tree in the Hammersmith 
Nursery, as there are of most species of Caragdna, and of Caléphaca wol- 
garica. Price, in the London nurseries, from 1s. to 2s. 6d., grafted standard 
high, 7s. 6d.; at Bollwyller, 1 franc 50 cents; and at New York, 1 dollar. 
% 2, H. (A.) suBvirE’scens Don. The greenish Halimodendron, or Salt Tree. 
Identification. Don’s Mill., 2. p. 244. , 
erie Er Robinia trifldra L’Hérit. Stirp. Nov., 162.; H. argénteum @ subviréscens Dec. Prod., 
Spec. Char., §c. Leaves greenish. The standard of the same length as that 
of the keel. Pedicels 3-flowered. (Don’s Mill., ii. p. 244.) A shrub, like 
the preceding one, of which it is, without doubt, only a variety.
