pale green. Stamens arising opposite the segments of the perianth, 

 with slender filaments, bearing large linear reflexed yellow two celled 

 anthers. Ovaries from three to six, having at the apex and side the 

 sessile stigma, which is linear, downy. Capsules from three to six, 

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

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

 valves, and from one to two seeded. Seeds oblong. 



Habitat. Marshy places ; rare. Discovered in a marsh at Lately 

 Car, near Boroughbridge, Yorkshire, by the Rev. J. Dalton ; and at 

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

Perennial ; flowering in June. 



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. *
