ew. The red or
scarlet fruit is showy and beautiful.

P. AUCUPARIA.--Mountain Ash, or Rowan Tree. Too well-known to need
description, but one of our handsomest small-growing trees, and whether
for the sake of its dense corymbs of small white flowers or large
bunches of scarlet fruit it is always welcomed and admired. P. Aucuparia
pendula has the branches inclined to be pendulous; and P. Aucuparia
fructo-luteo differs from the normal plant in having yellowish instead
of scarlet fruit.

P. AMERICANA (_syn Sorbus americana_).--American Mountain Ash. This
species, a native of the mountains of Pennsylvania and Virginia (1782),
is much like our Rowan Tree in general appearance, but the bunches of
berries are larger, and of a brighter red colour.

P. ANGUSTIFOLIA.--North America, 1750. A double-flowered crab is offered
under this name, of vigorous growth, bearing delicate pink, rose-like
flowers that are deliciously fragrant, and borne contemporaneously with
the leaves. The merits claimed for the shrub are perfect hardihood,
great beauty of blossom and leaf, delicious fragrance, and adaptability
to various soils. The single-flowered form extends over large areas in
the Atlantic States of North America. They are very desirable,
small-growing trees, and are described by Professor Sargent as being not
surpassed in beauty by any of the small trees of North America.

P. BACCATA.--Siberian Crab. Siberia and Dahuria, 1784. This is one of
the most variable species in cultivation, and from which innumerable
forms have been developed, that differ either in habit, foliage,
flowers, or fruit. The deciduous calyx would seem to be the only
reliable distinguishing character. It is a widely-distributed species,
being found in North China and Japan, Siberia and the Himalayas, and has
from time immemorial been cultivated by the Chinese and Japanese, so
that it is not at all surprising that numbers of forms have been
developed.

P. CORONARIA.--Sweet Scented Crab. North America, 1724. This is a
handsome species, with ovate, irregularly-toothed leaves, and pink and
white fragrant flowers. The flowers are individually large and
corymbose, and are succeeded by small green fruit.

P. DOMESTICA (_syn Sorbus domestica_).--True Service. Britain. This
resembles the Mountain Ash somewhat, but the flowers are panicled, and
the berries fewer, larger, and pear-shaped. The flowers are conspicuous
enough to render the tree of value in ornamental plantin
