them the Canary Water-lily (N. J. chromatella), with 
reddish brown leaves and soft yellow flowers, darkening 
to the centre, is very beautiful. N. Robinsoni is another 
fine variety with rose-coloured blooms, abundantly pro- 
duced. Our own native lily (N. alba) flowers early, and 
should be in every collection, but the variety rosea is a 
shy bloomer, though the colour is extremely pretty. 
N. tuberosa. 
Aponogeton.—The Cape Pond-flower. A pretty water 
plant, the flowers are white and delicately scented. It 
requires fairly deep water, and does best in a warm 
district. 4. distachyon. 
Villarsia. Yellow Buckbean. Small lily-like leaves, 
and a profusion of yellow flowers. 
Stratiotes.—Water Soldier. Interesting on account of 
its foliage. 
Shallow water is needed for the following :— 
Typha Latifolia.—The Common Bulrush. 
Sagittaria.— Arrowhead. Handsome plants with white 
blossoms and arrow-shaped leaves. 
Caltha Palustris.—Marsh Marigold. 
Pontederia.—Pickerel Weed. Graceful foliage, with 
spikes of blue flowers. 
Butomus Umbellatus—F lowering Rush. Bears umbels 
of rosy flowers. 
Menyanthes Trifoliata.—Buckbean. Grows freely, the 
scented white flowers being faintly suffused with pink. 
A few good plants for localising in marshy ground on 
the margin :— 
Iris Kaempferi. The Japanese Flag. A more strik- 
ingly beautiful subject for the position could scarcely be 
found. The sword-like foliage, and large handsome 
flowers render it especially noteworthy. 
Gunnera.—Prickly Rhubarb. Noble plants, with im- 
mense fan-shaped leaves. They should be slightly 
protected during winter.
