C. BIFLORUS (_syn C. elongatus_).--Hungary, 1804. This is a dwarf,
spreading, twiggy bush, of fully a yard high. Leaves trifoliolate,
clothed beneath with closely adpressed hairs, and bright yellow,
somewhat tubular flowers, usually produced in fours.

C. DECUMBENS.--A charming alpine species, of low, spreading growth,
bright-green three-parted leaves, and bearing axillary bunches of large
yellow, brownish-purple tinted flowers. A native of the French and
Italian Alps, and quite hardy.

C. NIGRICANS.--Austria, 1730. Another beautiful species, with long,
erect racemes of golden-yellow flowers, and one whose general hardihood
is undoubted. On its own roots, and allowed to roam at will, this
pretty, small-growing Broom is of far greater interest than when it is
grafted mop-high on a Laburnum stem, and pruned into artificial shapes,
as is, unfortunately, too often the case.

C. PURPUREUS.--Purple Broom. Austria, 1792. Alow, spreading shrub, with
long wiry shoots, clothed with neat trifoliolate leaves, and bearing an
abundance of its purple, Pea-shaped flowers. There is a white-flowered
form, C. purpureus albus, and another named C. purpureus ratis-bonensis,
with pretty yellow flowers, produced on long and slender shoots.

C. SCOPARIUS.--Yellow Broom. This is a well-known native shrub, with
silky, angular branches, and bright yellow flowers in summer. There are
several varieties, but the most remarkable and handsome is C. scoparius
Andreanus, in which the wings of the flowers are of a rich golden
brown. It is one of the showiest shrubs in cultivation.
