The Autumnal Water Starwort (CalKiriche autumnalis) is 

 decidedly a rare plant compared to the Yemal Starwort. It 

 grows in similar situations, but it does not, like that plant, ever 

 rise above the surface of the water. Its leaves are narrower 

 (Fig. 51) and of a daxker green. C. autumnalis is occasionally 

 found in the neighbourhood of London, and in some of the 

 northern lakes. A few inches of the top of a healthy spray

may be tied to a small stone and sunk in the water of the 

 aquarium. No two sprays should be tied together. 



The Water Crowfoot {Ranunculus aquatilis) (Fig. 52) is an 

 excellent plant for the aquarium, and one very easily procured, 

 as it is common almost everywhere. It grows in streams and 

 ponds, sometimes neaa-ly covering the latter with its beautiful 

 green leaves and its pretty flowers. .The leaves of this plant
