 attached at the base, and spreading around, roundish, inflated, some- 

 what compressed, acutely pointed, each of one cell, bursting with two

 Thorne Moor, near Doncaster, in the same County, by Mr. R.

This rare and remarkable plant was first discovered as a native of 

 this country, by the Rev. J. Dalton, in the year 1807, and by Mr. 

 Duff, in Scotland, in 1833. It is by no means a common plant on the 

 Continent, but is, according to Smith, more plentiful in Sweden, 

 Denmark, Norway, and Lapland. In many respects it will be ob- 

 served how nearly allied it is in the structure of its flowers and fruit 

 to the following genus.
