ble, as is also the dark purple
berries. It is very hardy, and of the freest growth.

B. TRIFOLIOLATA (_syn Mahonia trifoliolata_).--Mexico, 1839. This is a
very distinct and beautiful Mexican species that will only succeed
around London as a wall plant. It grows about a yard high, with leaves
fully 3 inches long, having three terminal sessile leaflets, and
slender leaf stalks often 2 inches long. The ternate leaflets are of a
glaucous blue colour, marbled with dull green, and very delicately
veined. Flowers small, bright yellow, and produced in few-flowered
axillary racemes on short peduncles. The berries are small, globular,
and light red.

B. TRIFURCA (_syn Mahonia trifurca_).--China, 1852. This is a shrub of
neat low growth, but it does not appear to be at all plentiful.

B. VULGARIS.--Common Barberry. This is a native species, with oblong
leaves, and terminal, drooping racemes of yellow flowers. It is
chiefly valued for the great wealth of orange-scarlet fruit. There are
two very distinct forms, one bearing silvery and the other black
fruit, and named respectively B. vulgaris fructo-albo and B. vulgaris
fructo-nigro.

B. WALLICHIANA (_syn B. Hookeri_).--Nepaul, 1820. This is exceedingly
ornamental, whether as regards the foliage, flowers, or fruit. It is
of dense, bushy growth, with large, dark green spiny leaves, and an
abundance of clusters of clear yellow flowers. The berries are deep
violet-purple, and fully half-an-inch long. Being perfectly hardy and
of free growth it is well suited for extensive planting.

BERCHEMIA.

BERCHEMIA VOLUBILIS.--Climbing Berchemia. Carolina, 1714. A rarely
seen, deciduous climber, bearing rather inconspicuous greenish-yellow
flowers, succeeded by attractive, violet-tinted berries. The foliage
is neat and pretty, the individual leaves being ovate in shape and
slightly undulated or wavy. It is a twining shrub that in this
country, even under favourable circumstances, one rarely sees
ascending to a greater height than about 12 feet. Sandy peat and a
shady site suits it best, and so placed it will soon cover a
low-growing tree or bush much in the way that our common Honeysuckle
does. It is propagated from layers or cuttings.

BIGNONIA.

BIGNONIA CAPREOLATA--Virginia and other parts of America, 1710. This
is not so hardy as to be depended upon throughout the country
generally, though in the milder parts of England and Ireland it
succeeds well as a wall plant. It is a han
