are
succeeded by a profusion of scarlet berries that ripen in autumn. This
is generally considered the best for garden purposes.

CRATAEGUS.

CRATAEGUS AZAROLUS.--South Europe, 1640. This is a very
vigorous-growing species, with a wide, spreading head of rather
upright-growing branches. The flowers are showy and the fruit large and
of a pleasing red colour.

C. AZAROLUS ARONIA (_syn C. Aronia_).--Aronia Thorn. South Europe,
1810. This tree attains to a height of 20 feet, has deeply lobed leaves
that are wedge-shaped at the base, and slightly pubescent on the under
sides. The flowers, which usually are at their best in June, are white
and showy, and succeeded by large yellow fruit. Generally the Aronia
Thorn forms a rather upright and branchy specimen of neat proportions,
and when studded with its milk-white flowers may be included amongst
the most distinct and ornamental of the family.

C. COCCINEA.--Scarlet-fruited Thorn. North America, 1683. If only for
its lovely white flowers, with bright, pinky anthers, it is well worthy
of a place even in a selection of ornamental flowering trees and
shrubs. It is, however, rendered doubly valuable in that the
cordate-ovate leaves turn of a warm brick colour in the autumn, while
the fruit, and which is usually produced abundantly, is of the
brightest red.

C. COCCINEA MACRANTHA.--North America, 1819. This bears some resemblance
to the Cockspur Thorn, but has very long, curved spines--longer, perhaps,
than those of any other species.

C. CORDATA is one of the latest flowering species, in which respect it
is even more hardy than the well-known C. tanace-tifolia. It forms a
small compact tree, of neat and regular outline, with dark green
shining leaves, and berries about the same size as those of the common
species, and deep red.

C. CRUS-GALLI.--Cockspur Thorn. North America, 1691. This has large
and showy white flowers that are succeeded by deep red berries. It is
readily distinguished by the long, curved spines with which the whole
tree is beset. Of this species there are numerous worthy forms,
including C. Crus-galli Carrierii, which opens at first white, and
then turns a showy flesh colour; C. Crus-galli Layi, C. Crus-galli
splendens, C. Crus-galli prunifolia, C. Crus-galli pyracanthifolia, and
C. Crus-galli salicifolia, all forms of great beauty--whether for their
foliage, or beautiful and usually plentifully-produced flowers.

C. DOUGLASII.--North America, 1830.
