Lychnis chalcedonica. - Scarlet Lychnis. - This is common in most gardens, under the name of London Pride. It is an. esteemed border flower, of easy cultivation. The flowers are brilliant scarlet, which make it more valuable, as comparatively few flowers of that color are to be found among hardy herbaceous plants. One of the most splendid decorations of the border is the Double Scarlet Lychnis. It is propagated only by divisions of the root, or cuttings of the flower-stem; the single variety is raised freely from seed. The cuttings are taken off at any time when the shoots are tender, and planted in a sandy loam, in a warm situation, but covered with a hand-glass and shaded from the sun. When well-established, they may be transplanted into the bed or border where they are to remain, and will flower strongly the next year. There is also a single and double white variety. All the varieties do best in a light, rich, loamy soil. It is necessary to take up and divide the roots every other year. The best time to do this is early in the spring. A light protection is necessary to the double varieties, to insure a vigorous bloom. The flowers are fascicled, (collected in bundles,) level-top or convex; two feet high; in June and July. The double varieties continue to give flowers until autumn.

L. fulgens, - splendid, - is a hardy species from Siberia, with scarlet flowers; one foot and a half high; not common with us.

L. coronata is a showy species from China. The flowers are large, solitary, terminal, and axillary, red, the petals torn; one foot and a half high. Unfortunately, this beautiful plant will not stand our winter in open ground; it therefore requires to be taken up and potted in autumn, and protected in the house or frame. It thrives and flowers abundantly most of the season, if planted out in the spring. It may be raised from seeds or cuttings.

L. jloscuculi. - Ragged Robin. - This is an old inhabitant of the flower-garden, a native of Britain. The double variety is deservedly esteemed, is very ornamental, easy to cultivate, and flourishes in any common garden soil. It is propagated by divisions of the root. Flowers fine deep pink.

L. viscaria, with pink; L. diurna, with purple; and L. vespertina, with white flowers, all natives of Britain, are hand-some border flowers in their double varieties.
