Tbe remarkable little water-plant upon which this genus is founded is a native of 

 the United States of North America and Canada, and was found early in the present 

 century by Mr. Brown in Australia, and latterly by Griffith in the Khasia Mountains 

 and Bhotan. Being inconspicuous, it is probably not so rare as is supposed to be the 

 case. 'SVe are quite unable to detect any difference between our specimens which we 

 have preserved in spirits, and the excellent analysis in Gray's ' Genera of tfnited 

 States Plants,' except that the tilaments and dorsum of the sepals are puberulous. 



Asa Gray observes that the curious mucilaginous covering of the peduncles and pe- 

 tioles is formed by the rapid formation and rupturing of successive epithelial cells, as 

 mucilage is formed on the surfaces of animal mucous membranes ; we may observe that 

 the gelatinous coat of the seeds of various Composites and Crucifera is quite analo- 

 gous. Gray further states that the rhizoma contains oblong transversely annulated 

 starch-grains of unusual size, the larger being g-^ inch long.
