Balsamodéndron gileadénse Kunth, and Don’s Mill., 2. p. 81.; the Amfris 
gileadénsis of Lin. (Vahl Symb., 1. p. 28. t.11.; and our jig. 235, represent- 
ing a branch, drawn to our usual scale of 2 in. to 1 ft., and fig. 236. representing 
the flower and fruit of the natural size), the Balm of Gilead tree, isa native of 
Arabia, with leaves palmately trifoliate, and small whitish flowers. There are 
. . twoor three varieties of it, which are by some con- 
> sidered species, but none of them have yet been 236 
introduced into Britain. — Candrium Piméla 
Konig. (Don’s Miil., 2. p. 85.) is a tree with com- 
pound leaves, growing to the height of 50 ft. in 
the woods of Cochin-China and Java. 
Fagastrum G. Don. (Don’s Mill., p. 87.) is a 
Cape genus, containing several species of ever- 
green shrubs, with alternate pinnate leaves, some 
of which may probably prove hardy ; but none of 
which have hitherto been introduced. 

CHAP. XL. 
OF THE HALF-HARDY LIGNEOUS SPECIES OF THE ORDER 
AMYRIDA‘CEX. 
Amiyris toxtfera Willd., the A. balsamffera of L. and Cat. Car. t. 40., isa tree with compound 
leaves, a native of Carolina, and growing to the height of 50ft. It is commonly kept in green- 
houses ; but there can be little doubt, from the climate of its native country, that it would succeed 
against a conservative wall. The fruit is produced in racemes, and it is pearl-shaped and purple. 
From the trunk of the tree a juice distils as black as ink, which is reported to be poisonous. The 
leaves, in a dried state, are highly cephalic. This species was introduced in 1820, but it is not common. 
It well deserves a place in collections, as the representative of a genus containing various species 
interesting in medicine and the arts. 
A. floridina Nutt. is a shrub, growing to the height of 10 ft. in Eastern Florida, with reticulately 
veined, glandular, resinous, and fragrant leaves, and black berries, about the size of those of black 
pepper. When introduced, it will doubtless be found half-hardy. 
CHAP. XLI. 
OF THE HARDY LIGNEOUS PLANTS OF THE ORDER LEGUMINA‘CE. 
Tue name of Leguminacez is applied to this extensive and truly natural 
order, on account of the seeds of all the species being produced in leguminous 
pods, bearing more or less resemblance to those of the common pea or bean; 
and quite different from the siliquose pods of cruciferous plants. 
The Distinctive Characteristics are: Calyx with 5 divisions, either parti- 
tions, teeth, or clefts, the odd one anterior to the axis of inflorescence. 
Fruit a legume. Seed with the radicle next the hilum. (Lindley, Introd. 
to N.S., and Key.) The ligneous species are trees and shrubs, for the 
most part deciduous; and they are disposed through almost every part of 
the world. The order contains some of our finest ornamental shrubs and low 
trees, such as Robinia, Cytisus, Wistaria, Genista, U‘lex, Amérpha, Halimo- 
déndron, Acacia, Gleditschia, Cércis, and various others. It also contains 
some considerable trees, which belong to the genera Robinia, Gleditschia, 
Sophora, &c. The genera containing hardy ligneous plants are in number 
twenty-three, which, after De Candolle and G. Don, we place in characterised 
sections, and ascribe to them short characters, that are more or less contra- 
distinctive.
