shining, integument coriaceous; episperm white and mém- 
branaceous. Nucleus greenish, consisting of an ovate cy- 
lindric and homogenous somarhize, marked at its inferi- 
or extremity (or contiguous to the umbilicus) with an al- 
Most imperceptibly minute gemmule, in the form of a 
diaphanous point. 
‘The only species of the genus, common to morasses in 
the north of Europe. From the singularly isolated occur- 
rence of this plant in the milder states of America, Iam 
inclined to believe it on the decrease in such situations. — 
Jn the turf morasses, or moors as they are called, in the 
northern parts of Yorkshire, (Craven) in England, I have 
commonly seen the singular vestiges of this plant inlayed 
through spongy or more recent turf, obtained where none

of the plant exists at the present day.
