the leaves are small and round, and die off crimson in autumn.

B. STENOPHYLLA, a hybrid between B. Darwinii and B. empetrifolia, is
one of the handsomest forms in cultivation, the wealth of
golden-yellow flowers being remarkable, 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
