4.  Anthemis maritima.  A double-flowering variety of this plant used to be common in the gardens near London, but is now scarce:  it is very beautiful, and constantly in bloom during summer.  It is propagated by planting the roots in the spring and autumn.

5.  Antirrhinum linaria, v.  Peloria.—­I cannot pass over this singular and beautiful flower without notice.  There is a fine figure of it in the Flora Londinensis:  it is very ornamental, and the structure of the bloom is truly interesting.  It is easily propagated by planting the roots in the spring months, but it is not common.

6.  Antirrhinum majus.  Snapdragon.—­This is also a plant deserving the attention of the lover of flowers:  it is capable of culture into many very beautiful and interesting varieties.

7.  Bellis perennis.  Daisy.—­This plant affords us many very beautiful varieties for the flower garden.  The large Red Daisy and all the other fine kinds are only this plant improved by culture.

8.  BUTOMIS umbellatus.  This is an aquatic, and well adapted to ornament pieces of water.  Its beautiful flowers in the summer months are inferior to scarcely any plants growing in such places, and its foliage will form protection for any birds, &c., which are usually kept in such places.  It is easily propagated by planting it in such places.

9.  Caltha palustris.  Marsh Marigold.—­This fine yellow flower is also made double by culture, and finds a place in the flower garden.

10.  Cheiranthus fruticulosus.  Wallflower.—­Is a plant possessing great beauty, and very interesting on account of its fine scent.  We have this plant also improved by culture, making many fine double varieties.  It is a biennial, and easily raised from seeds, which should be sown in June.  The double varieties are cultivated by cuttings of the branches.

11.  Cypripedium Calceolus.  Ladies Slipper.—­A flower of the most uncommon beauty, but is now become scarce; it is a native of the woods near Skipton in Yorkshire, but has been so much sought for by the lovers of plants as to become almost extinct.  It is difficult to propagate; but when the plants have been for some years growing, will admit of being parted, so that it may be increased in that way:  it will not bear to be often removed, and should be left to grow in the same place for several years without being disturbed.  It succeeds best in bog earth or rotten leaves.

12.  Delphinium Ajacis.  Larkspur.—­This is also an annual flower, affording a pleasing variety in the flower garden in the summer months.  For it culture, see p. 188.

13.  Dianthus Caryophyllus.  The carnation.—­All our fine varieties of the carnation are the produce of this plant.

The common single variety produces seed in great abundance, but the improved double varieties are sparing in produce:  the fine kinds of this flower are reared by layers put down about the month of July; they may also be propagated by cuttings, but the other is the most eligible and certain mode.
