fruit are concerned, one of the most distinct and desirable species of
Thorn.

Other good species and varieties that may just be mentioned as being
worthy of cultivation are C. apiifolia, C. Crus-galli horrida, C.
orientalis, and C. tomentosum (_syn C. punctata_). To a lesser or
greater extent, the various species and varieties of Thorn are of great
value for the wealth and beauty of flowers they produce, but the above
are, perhaps, the most desirable in that particular respect. They are
all of free growth, and, except in waterlogged soils, thrive well and
flower freely.


CYTISUS.

CYTISUS ALBUS.--White Spanish Broom. Portugal, 1752. This is a
large-growing shrub of often 10 feet in height, with wiry, somewhat
straggling branches, and remarkable for the wealth of pure-white
flowers it produces. In May and June, if favourably situated, every
branch is wreathed with small white flowers, and often to such an
extent that at a short distance away the plant looks like a sheet of
white. Being perfectly hardy and of very free growth in any light soil,
and abundantly floriferous, this handsome shrub is one of particular
value in ornamental planting. By placing three or five plants in
clump-fashion, the beauty of this Broom is greatly enhanced.

C. ALDUS INCARNATUS (_syn C. incarnatus_) resembles C. purpureus in its
leaves and general appearance, but it is of larger growth. The flowers,
which are at their best in May, are of a vinous-rose colour, and
produced plentifully.
