OR, THE HOME-CULTURE OF FRESH-WATER PLANTS. 
The pretty plant growing with it, in the same 
Plate, is the Sundew, which delights also in damp 
situations. Its leaves delicately fringed with pink, 
and its pretty rose-coloured blossoms, combined 
with its general neatness of growth, make it a 
generally desirable plant for the Aquarium, in 
which, with proper care, it thrives well. 
In the centre of the vessel I have placed an 
Arum (Cctlla JEthiopica ), a plant which always 
flourishes best in water, forming a truly magnifi¬

have seen it introduced with great success. In 
such situations it dies down, in the winter; hut 
protected by a sufficient depth of water, does not 
suffer from any degree of frost, though a very slight 
one is sufficient to destroy it when grown in a pot. 
In the Aquarium it forms a very beautiful object. 
The foliage rises like a column of some semi-trans¬ 
parent green marble through the water, spreading 
into a finely foliaged capital above; and when the 
flowers eventually shoot up from this fine coronet 
of elegantly formed leaves, the effect is magnificent. 
But, even before the appearance of the flowers, there

graceful Calla. Among aquatic flowering plants,
