modi variegata, and another
named S. Emodi villosa, both good varieties.

S. JAPONICA (_syns S. amurensis_ and _Ligustrina amurensis_).--Japan.
This is of recent introduction, and is a decided acquisition, producing
in summer large and dense clusters of creamy-white flowers. It is a very
desirable species, and though coming from Japan seems to be perfectly
hardy.

S. JOSIKAEA, Josika's Lilac, is of Hungarian origin (1835), and is so
totally different from the others as to be well worthy of special
attention. It rarely exceeds 6 feet in height, with dark-green, wrinkled
leaves, and erect spikes of pale mauve flowers.

S. PERSICA (Persian Lilac).--Persia, 1640. This is a distinct
small-growing species, with slender, straight branches, and lilac or
white flowers produced in small clusters. The form bearing white flowers
is named S. persica alba; and there is one with neatly divided foliage
called S. persica laciniata.

S. VULGARIS.--Common Lilac, or Pipe Tree. Persia and Hungary, 1597. This
is one of the commonest and most highly praised of English garden
shrubs, and one that has given rise, either by natural variation or by
crossing with other species, to a great number of superior forms. The
following include the best and most ornamental of the numerous
varieties:--alba, pure white flowers; alba-grandiflora, very large
clusters of white flowers; alba-magna, and alba virginalis, both good
white-flowering forms; Dr. Lindley, large clusters of reddish-lilac
flowers; Charles X., purplish-lilac flowers, but white when forced;
Souvenir De Ludwig Spath, with massive clusters of richly coloured
flowers; Glorie de Moulins, Marie Legrange, Noisetteana, Duchesse de
Nemours, and Vallettiana, all beautiful flowering forms that are well
worthy of cultivation, and that are of the simplest growth.

The double-flowered varieties, for which we are much indebted to M.
Victor Lemoine, of Nancy, are fast gaining favour with cultivators in
this country, and rightly, too, for they include several very handsome,
full flowered forms. The following are best known:--

S. vulgaris Alphonse Lavallee, with full double red flowers, changing
to mauve.
" Emile Lemoine, mauve-pink, suffused with white; very
handsome.
" La Tour d'Auvergne, mauve shaded with rose. A beautiful
and very dark coloured form.
" Lemoinei, nearly resembling our common species, but with
