greenish-yellow
flowers, faintly tinted with pinky-purple.

C. MICROPHYLLA (_syn C. Altagana_), also from Siberia, is smaller of
growth than the foregoing, but the flowers are individually larger. It
is readily distinguished by the more numerous and hairy leaflets and
thorny nature.

C. SPINOSA.--Siberia, 1775. This, as the name indicates, is of spiny
growth, and is a beautiful and distinct member of the family. They are
all hardy, and readily propagated from seed.

CARDIANDRA.

CARDIANDRA ALTERNIFOLIA.--Japan, 1866. With its neat habit, and pretty
purple-and-white, plentifully-produced flowers, this is worthy of the
small amount of care and coddling required to insure its growth in this
country. Hailing from Japan, it cannot be reckoned as very hardy, but
treated as a wall plant this pretty evergreen does well and flowers
freely. It can, however, be said that it is equally hardy with some
of the finer kinds of Hydrangea, to which genus it is nearly allied.

CARPENTERIA.

CARPENTERIA CALIFORNICA.--Sierra Nevada, California, 1880. This is
undoubtedly one of the most distinct and beautiful of hardy shrubs.
That it is perfectly hardy in England and Ireland recently-conducted
experiments conclusively prove, as plants have stood unprotected
through the past unusually severe winters with which this country has
been visited. When in full bloom the pure-white flowers, resembling
those of the Japanese Anemone, render it of great beauty, while the
light gray leaves are of themselves sufficient to make the shrub one of
particular attraction. The Carpenteria is nearly related to the Mock
Orange (Philadelphus), grows about 10 feet in height, with lithe and
slender branches, and light gray leaves. The flowers, which are pure
white with a bunch of yellow stamens, and sweet-scented, are produced
usually in fives at the branch-tips, and contrast markedly with the
long and light green foliage. It grows and flowers with freedom almost
anywhere, but is all the better for wall protection. From cuttings or
suckers it is readily increased.

CARYOPTERIS.

CARYOPTERIS MASTACANTHUS.--China and Japan, 1844. This is a neat-growing
Chinese shrub, and of value for its pretty flowers that are produced
late in the autumn. It must be ranked as fairly hardy, having stood
through the winters of Southern England unprotected; but it is just as
well to give so choice a shrub the slight protection afforded by a
wall. The leaves are neat, th
