ava (_syn Pavia flava_) bearing
pretty yellow flowers; Ae. Pavia macrocarpa (_syn Pavia macrocarpa_)
an open-headed and graceful tree; Ae. flava discolor (_syn Pavia
discolor_); and Ae. chinensis; but they have not been found very
amenable to cultivation, except in very favoured parts of the South of
England and Ireland.

AILANTHUS.

AILANTHUS GLANDULOSA.--Tree of Heaven. China, 1751. A handsome,
fast-growing tree, with large pinnate leaves that are often fully
three feet long, and terminal erect clusters of not very showy
greenish-white flowers that exhale a rather disagreeable odour. It is
one of the most distinct and imposing of pinnate-leaved trees, and
forms a neat specimen for the lawn or park. Light loam or a gravelly
subsoil suits it well.

AKEBIA.

AKEBIA QUINATA.--Chinese Akebia. China, 1845. This, with its
peculiarly-formed and curiously-coloured flowers, though usually
treated as a cool greenhouse plant, is yet sufficiently hardy to grow
and flower well in many of the southern and western English counties,
where it has stood uninjured for many years. It is a pretty twining
evergreen, with the leaves placed on long slender petioles, and
palmately divided into usually five leaflets. The sweet-scented
flowers, particularly so in the evening, are of a purplish-brown or
scarlet-purple, and produced in axillary racemes of from ten to a
dozen in each. For covering trellis-work, using as a wall plant, or to
clamber over some loose-growing specimen shrub, from which a slight
protection will also be afforded, the Akebia is peculiarly suitable,
and soon ascends to a height of 10 feet or 12 feet. Any ordinary
garden soil suits it, and propagation by cuttings is readily affected.

AMELANCHIER.

AMELANCHIER ALNIFOLIA.--Dwarf June Berry. N.W. America, 1888. This
is a shrub of great beauty, growing about 8 feet high, and a native of
the mountains from British America to California. This differs from A.
canadensis in having much larger and more brilliant-tinted fruit, and
in its shorter and more compact flower racemes. The shape of the
leaves cannot be depended on as a point of recognition, those before
me, collected in the native habitat of the plant, differing to a wide
extent in size and shape, some being coarsely serrated while others
are almost entire.

A. CANADENSIS.--June Berry. Canada, 1746. Unquestionably this is one
of the most beautiful and showy of early flowering trees. During the
month of April
