ONLY GENUS. 

 Parnassia. 



The genus Parnassia, long annexed to Droseracece, only approaches them in its parietal placenta (see 

 this family). Its bundles of staminodes and its exalbuminous seeds bring it near Hypericinete, but other 

 characters separate it from them, and especially the extrorse anthers. It has been more correctly com- 

 pared with Saxifragece. The few species of this genus inhabit the temperate and cool regions of the 

 northern hemisphere, especially in America ; they are rare [common] on the high mountains of tropical 

 Asia. The Grass of Parnassus (P. pahistris), an indigenous plant, is a bitter and astringent herb, formerly 

 used as a diuretic and anti-ophthalmic ; a decoction of it is in Sweden added to beer, and stomachic 

 virtues are attributed to it.
