t forms a pretty
bush often fully a yard in height. The leaves resemble those of some
species of Willow, being long and narrow, while the showy yellow flowers
are freely produced in August and September. It thrives best when
planted in light, dry soil, and in a sheltered position.

NEVIUSA.

NEVIUSA ALABAMENSIS.--Alabama Snow Wreath. Alabama, 1879. This is a rare
American shrub, with leaves reminding one of those of the Nine Bark,
Neillia opulifolia, and the flowers, which are freely produced along the
full length of the shoots, are white or yellowish-green, with prominent
stamens of a tufted brush-like character. It is usually treated as a
green-house plant, but may be seen growing and flowering freely in the
open ground at Kew.

NUTTALLIA.

NUTTALLIA CERASIFORMIS.--Osoberry. California, 1848. This shrub is of
great value on account of the flowers being produced in the early weeks
of the year, and when flowers are few and far between. It grows from 6
feet to 10 feet high, with a thick, twiggy head, and drooping racemes of
white flowers borne thickly all over the plant. Few soils come amiss to
this neglected shrub, it growing and flowering freely even on poor
gravelly clay, and where only a limited number of shrubs could succeed.

OLEARIA.

OLEARIA HAASTII.--New Zealand, 1872. This Composite shrub is only hardy
in the milder parts of England and Ireland. It is of stiff, dwarf
growth, rarely growing more than 4 feet high, but of neat and compact
habit. Flowering as it does in late summer it is rendered of special
value, the Daisy-like white blossoms being produced in large and flat
clusters at the branch tips. The leaves are neat and of leathery
texture, and being evergreen lend an additional charm to the shrub.

O. MACRODONTA (_syn O. dentata_), from New Zealand, 1886, is tolerably
hardy, and may be seen in good form both at Kew and in the South of
Ireland. The large Holly-like leaves are of a peculiar silvery-green
tint above, and almost white on the under sides. Flowers white, and
produced in dense heads in June and July.

O. Forsterii and O. Gunniana (_syn Eurybia Gunniana_) are nearly hardy
species, the latter, from New Zealand, bearing a profusion of white
Daisy-like flowers on dense, twiggy branches.

ONONIS.

ONONIS ARVENSIS.--Restharrow. A native undershrub of very variable size,
according to the position in which it is found growing. It creeps along
the ground, the shoots sending out roots
