tHs on account of its singular character. It forms 

 rosettes of narrow senrated olive -green leaves atout 

 a foot long, and these are anchored to the hottom by 

 means of long roots; they rise to the surface to 



flower in summer, hut sink again afterwards. Clear 

 water is best for the beauty of this plant, as other- 

 wise sediment is deposited on the leaves. In a gTcen- 

 house tank we have seen very attractive specimens. 

 It increases itself by offsets, but is not always easy 

 to establish, though sometimes it increases rapidly. 

 It grows chiefly in the East of England, in fen 

 ditches, and is a native of Europe and Siberia. The 



flowers are white, but not atti^active. Jvino t^>

 common Buii-ush, of which the cylindrical Lrowu 



spikes are often prized for room decoration, associated 

 with Pampas-gi-ass and similar diy ornaments. It is 

 an extremely ornamental subject for ponds, where 

 the tall waving leaves afford a distinct and pleasing 

 effect. The leaves grow from a creeping rhizome m 

 two opposite rows, they are an inch or more broad, 

 and three to six feet long. The spike-bearing stems 

 about equal the leaves in length, and the spikes are 



TXPHA LAXIFOLIA.
