Geographical Distribution. 



Budbeck and Linnaeus found this plant (Fl. Lap. n. 159.) 

 in the Kemi-elf, therefore under the polar circle. Wahlenberg, 

 however, who searched this stream in the year 1802, has not 

 mentioned this plant, as if it did not grow in Lapland. But 

 it is certain, that in Europe and Asia it passes beyond the 63® 

 N. Lat,, for J. G. Gmelin found it on the banks of the Obi 

 and Jrtisch, {Fl. Sib. 1. p. 77.) How far towards the Equa- 

 tor it stretches, has not been determined ; but Sibthorp found 

 it in Asia Minor, as far as the 38° N. Lat. (Smith, Prodr. 

 Fl. Grac, 1. p. 269.) From east to west, it stretches from 

 Ochozk to Lisbon. It is not found in America. Between 

 the tropics, Hydrogeton and Hydrocleis seem to supply its 

 place. 



Uses. 



Baskets are made of its leaves, and in Holland matts are 

 formed from it. The tuber of the root, rich in starch, is pre- 

 pared and used as an ingredient in bread, (Wredow'^s Oeko- 

 nom. Flor. Mecklenb. 2. 209.)
