RIVER GARDENS, 
name, Hottonia , in honour of the well-known 
Dutch botanist, Hotton. 
The Water Crowfoot, or White Water Butter¬ 
cup, should always form one of the plant-collec¬ 
tion in an Aquarium, on account of its peculiar and 
interesting growth. The leaves of this plant, while 
they grow beneath the water, are so deeply cc cut ” 
or branched, as to appear almost fibrous in their 
character, like those of the class of plants which 
never appear above the surface. But the fibres of 
those leaves which are developed above the water 
become connected by the same kind of tissue as 
that which usually connects the veins of ordinary 
aerial leaves. In this new condition the upper 
foliage assumes quite a different character, and the 
plant has thus the appearance of being furnished 
with leaves of two remarkably distinct kinds. 
The common Brooklime, though rather coarse 
in its growth, puts forth its racemes of pretty blue 
flowers very abundantly; and the esculent Water¬ 
cress is also worthy of cultivation in the Aquarium, 
especially when treated in the following manner :—A 
few seeds should be procured, which can he purchased 
of any of the leading seedsmen, and sown in the 
bottom of the tank, where they will soon produce a 
very pretty green crop, over the undulations of the
