S. TETRAPTERA.--New Zealand, 1772. This requires protection in this
country. It is a valuable species, having numerous leaflets, and bearing
racemes of very showy yellow flowers. S. tetraptera microphylla is a
smaller-leaved variety, with ten to forty pairs of leaflets, and is
known in gardens under the names of Edwardsia Macnabiana, and E.
tatraptera microphylla.


SPARTIUM.

SPARTIUM JUNCEUM (_syn S. acutifolium_).--Spanish, or Rush Broom.
Mediterranean region and Canary Isles, 1548. This resembles our common
Broom, but the slender Rush-like branches are not angular, and usually
destitute of leaves. The fragrant yellow flowers are produced abundantly
in racemes, and when at their best impart to the shrub a very striking
and beautiful appearance. For planting in poor, sandy or gravelly soils,
or amongst stones and shingle, and where only a very limited number of
shrubs could be got to grow, the Spanish Broom will be found an
excellent and valuable plant. It is a native of Southern Europe, and is
quite hardy all over the country. Propagated from seed.


SPIRAEA.

SPIRAEA BELLA.--Pretty-flowered Spiraea. Himalayas, 1820. The reddish
stems of this rather tall-growing species are of interest, and render
the plant distinct. Leaves ovate, acute, and serrated, and tomentose
beneath. Flowers in spreading corymbs of a very beautiful rose colour,
