27.  Impatiens Noli me tangere.—­A very curious flower which is grown as an annual.  The construction of the seed-vessel causing the seeds to be discharged with an elastic force is a pleasing phaenomenon.

28.  Lathyrus sylvestris.—­Everlasting pea.—­This is also a great ornament, and frequently found in gardens; it grows very readily from seeds sown in the spring of the year.

29.  LEUCOJUM aestivum.  Summer Snow Flake.—­This is a very noxious plant in the meadows where it grows wild.  I have seen it in the neighbourhood of Wooking in Surrey quite overpower the grass with its herbage in the spring, and no kind of that animal that we know of will eat it.

It is however considered an ornamental plant, and is often found in our flower gardens.  It is of easy culture:  the roots may be planted in any of the autumn or winter months.

30.  Malva moschata.  Musk mallow.—­This makes a fine appearance when in bloom, for which purpose it is often propagated in gardens:  its scent, which is strong of vegetable musk, is also very pleasant.

31.  MELLITIS mellyssophyllum.  MELLITIS grandiflora.  Bastard balm.—­Both these plants are very beautiful, and are deserving a place in the flower garden:  they are of easy culture, and will grow well under the shade of trees, a property that will always recommend them to the notice of the curious.

32.  MENYANTHES Nymphoides.  Round-leaved bog bean.—­This is a beautiful aquatic, and claims a place in all ornamental pieces of water.

33.  Narcissus poeticus.  Narcissus Pseudo Narcissus.—­These are much cultivated in gardens for the sake of the flowers.  The florists have by culture made several varieties, as Double blossoms which are great ornaments.  The season for planting the bulbs of Narcissus of all kinds is the month of October:  they will grow well in any soil, and thrive best under the shade of trees.

34.  NUPHAR minima is also beautiful, but it is not common.  It will form an ornament for pieces of water.

35.  NYMPHAEA alba.  NYMPHAEA lutea.—­These are aquatics, and scarcely any plant is more deserving of our attention.  The fine appearance of the foliage floating on the surface, which is interspersed with beautiful flowers, will render any piece of water very interesting:  it should also be observed that gold-fish are found to thrive best when they have the advantage of the shade of these plants.  It is difficult in deep water to make them take root, being liable to float on the surface, in which state they will not succeed.  But if the plants are placed in some strong clay or loam tied down in wicker baskets and then placed in the water, there is no fear of their success:  they should be placed where the water is sufficiently deep to inundate the roots two feet or a little more.
