WATER LILIES AND OTHER AQUATIC PLANTS 263 



is a delightful flower. Add to these such things as the Water 

 Flag (Iris Pseudacorus), the Marsh Marigold (Caltha palustris), the 

 Japanese Primrose (Primula Japonica), which never does so well 

 as in moist soil near water, and may therefore be included with 

 the Aquatics without over-straining a point; the Grass of Par- 

 nassus (Parnassia palustris), the Arrowhead (Sagittaria sagittifolia), 

 the flowering rush (Butomus umbellatus), the Rosy Primrose 

 (Primula rosea), to which the remarks made in connection with 

 the Japanese Primrose apply ; Trapa natans and Azolla Caroliniana, 

 both with floating leaves; Alisma Plantago, Limnanthemum nym- 

 phoides, Acorus Calamus, Pontederia cordata, the Arum Lily 

 (Richardia Africana) in mild districts only add, we repeat, these 

 things, and a most beautiful selection is provided. 



All of the foregoing may be grown out of doors, but a few of 

 the Nymphaeas, such as gigantea, Devoniensis, and stellata; also 

 the beautiful Nelumbium (the Sacred Bean or Egyptian Lotus), 

 which is fragrant, and has many varieties ; the extraordinary 

 Eichornia, and the Lattice leaf plant (Aponogeton fenestrale, or 

 Ouvirandra fenestralis as it is called), the lace-like leaves of which 

 float on the water, require cultivation under glass. 



It cannot be expected that every amateur is in a position to 

 grow the whole of the plants named, but he can at least manage 

 a few Nymphaeas. Should he say that he has no pond, we say: 

 " Make a pool." If he should reply that he has neither space nor 

 means even for this, we still have an answer, and it is : " Grow 

 them in tubs." Several of the smaller sorts, such as Nymphaea 

 odorata minor, a small form of the scented Water Lily ; pygmaea 

 or tetragona, white, flowering in June, and its yellow variety 

 Helveola; also the hybrids James Brydon, Marliacea carnea, and 

 Marliacea chromatella, which are respectively red, pink, and yellow, 

 do admirably in tubs. These sorts are not like the old British 

 Water Lily, Nymphaea alba, in wanting deep water. They are 

 more at home in a depth of twenty to thirty inches.
