One o f the handsomest of evergreen shrubs, attaining the height of 6 ft.
in 6 years, quite hardy, producing a profusion of bunches o f yel ow flowers
durin« April and May. In its native country it grows m rich vegetable
soil ¿no n « rocks, or in woods, where it forms a thick and rich undergrowth.
Accordin« to Dr. Lindley, it is “ perhaps the handsomest hardy evergreen
we yet possess. Its foliage is of a rich, deep, shining green, becoming'
iiurple in the w in te r; it bears fruit in some abundance, which c o n s is ts o t
clusters of roundish black berries, having their surface covered with a rich
violet bloom. I t most resembles M. fasciculàris, from which its large shiniug
leaves a t once distingui.sh it.” (Fenny Cyc., iv. p. 262.) Layers and seeds.

North-west of

woods. Height 2 ft. to 3 ft.
Introd. in 1822. Flowers
yellow; October to March,
blue ; ripe in July.
According to Torrey and Gray, the stem is so low, th a t it often scarcely
rises from the ground, and, indeed, is much shorter than the leaves, which
are 1 ft. to 2 ft. in length. Racemes spi-
cate, often 6 in. to 8 in. long. Flowers
larger than in M. riquifòlium. The petioles
of the leaves. Dr. Lindley says,
“ are jointed at every pair of leaflets,
in the manner o f a bamboo stein.”
The plant is hardy, and will thrive in
a shady border o f peat soil. One of
the handsomest o f undershrubs.

Variety.
« M . r. 2 rèpens-fascìculàris. — Habit of M. fasciculàris, with larger and
more robust foliage, resembling th a t of M. rèpens. A sport, or a
hybrid, [iroduced accidentally in the Sawbridgeworth Nursery.
The shoots consist chiefly o f short iinbranched suckers, with the leaves somewhat
glaucous on both surfaces. The racemes o f flowers are terminal, numerous,
fascicled, diffuse, rising from scaly buds. The plant, in British gardens, is
perfectly hardy, and produces a profusion of rich yellow flowers in April
and May. Layers or suckers ; but it does not root readily. Seeds are
sometimes produced.
Other Species o f Mahonia, are no doubt in British gardens ; but as they
have been only raised lately from Nepal or Mexican seeds, nothing can be
recorded of them with th a t degree o f certainty and detail which is suitable
for this work. Mahònia tenuifòlia, a Mexican species with pinnate
leaves, and entire quite smooth leaflets, on very long slender footstalks, has
been raised in the Horticultural Society’s Garden, and may probably be as
hardy as M. fasciculàris ; but this is uncertain. M . nepalénsis, M . ajcanthi-
folia, M . tragacanthòìdes, and M . caraganse/ó/ia, are said lo be very desirable
species.

O r d e r VII. CRUCIA'CE.®.
O r d . C h a r . The order Cruciàceie is readily recognised by the cruciform
arrangement o f the petals, which are always lour, in conjunction with tetra-
dynamous stamens, and the fr u it a silique or silicic. — Though there are
several species which, technically considered, are ligneous plants, such as
rilyssum saxatile, ib è ris sempervìrens, Cheirànthus 6’èrìri, and some others;
yet, in a popular point of view, the only shrub included in the order is the
Fella Pseudo-Cytisus.

Derivation. T h e word Fèlla is Latin ised from th e word velar, the Celtic name o f th e cress.
Gen. Char. Stamens the 4 longer in 2 pairs, the 2 of each pair grown together.
Style ovate, flat, tongue-shaped, a t the tip of the silicle. Silicle ovate, compressed,
its valves concave. Partition elliptic. Cotyledons folded, the embryo
root disposed in the sinus o f the fold. (Dec. Syst.)
Leaves simple, alternate, exstipulate, sub-evergreen ; toothed or serrated,
glaucous. Flowers in axillary spikes, yellow, seldom succeeded by seed pods
in the climate of L ondon.— Shnih low, suffruticose, native of Spain.
