in small globular heads, bright orange or yellow,
and being plentifully produced are very showy in early summer. It
succeeds well in rich moist loam on gravel.

B. LINDLEYANA.--China, 1844. This has purplish-red flowers and angular
twigs, but it cannot be relied upon unless in very sheltered and mild
parts of the country.

B. PANICULATA (_syn B. crispa_).--Nepaul, 1823. This may at once be
distinguished by its curly, woolly leaves, and fragrant lilac flowers.
It is a desirable species, but suffers from our climate.

BUPLEURUM.

BUPLEURUM FRUTICOSUM.--Hare's Ear. South Europe, 1596. A small-growing,
branching shrub, with obovate-lanceolate leaves, and compound umbels
of yellowish flowers. It is more curious than beautiful.

CAESALPINIA.

CAESALPINIA SEPIARIA (_syn C. japonica_).--India, 1857. This is as yet
a comparatively little known shrub, but one that from its beauty and
hardihood is sure to become a general favourite. Planted out in a
light, sandy, peaty soil, and where fully exposed, this shrub has done
well, and proved itself a suitable subject for the climate of England
at least. The hard prickles with which both stem and branches are
provided renders the shrub of rather formidable appearance, while the
leaves are of a peculiarly pleasing soft-green tint. For the flowers,
too, it is well worthy of attention, the pinky anthers contrasting so
markedly with the deep yellow of the other portions of the flower.
They are arranged in long racemes, and show well above the foliage.

CALLUNA.

CALLUNA VULGARIS (_syn Erica vulgaris_).--Common Ling on Heather. This
is the commonest native species, with purplish-pink flowers on small
pedicels. There are many very distinct and beautiful-flowering forms,
the following being some of the best: C. vulgaris alba, white-flowered;
C. vulgaris Hammondi, C. vulgaris minor, and C. vulgaris pilosa, all
white-flowered forms; C. vulgaris Alportii, and C. vulgaris Alportii
variegata, the former bearing rich crimson flowers, and the latter with
distinctly variegated foliage; C. vulgaris argentea, and C. vulgaris
aurea, with silvery-variegated and golden foliage; C. vulgaris
flore-pleno, a most beautiful and free-growing variety, with double
flowers; C. vulgaris Foxii, a dwarf plant that does not flower freely;
and C. vulgaris pumila, and C. vulgaris dumosa, which are of small
cushion-like growth.

CALOPHACA.

CALOPHACA WOLGARICA.--Siberia, 1786. This member of the Pea f
