4 oi Nojas ; I oi Ruppia (Soonderbuns, Griffith,)/ 1 oi Zannichellia ; 13 

 of Potamogeton ; 4 of Spathium ; and — of Epigynanthus . Royle mentions, 

 that Rottl. herb, contains numerous specimens of Ruppia, under the name 

 of Zannichellia indica. Perhaps this species may be the same with that of 

 the Soonderbuns. With the Cape species of Aponogeton we are not ac- 

 quainted. " Properties unimportant. The root of Potamogeton natans is 

 said to be eaten in Siberia. Zostera, or Sea-wrack, is a common material 

 for packing, or for stuffing cottager's cushions." (Lindl.)
