Stem somewhat twisted. Whilst it is in flower, the germen 

 , having neither style nor summit, is open at the top. The stam. 

 lay their anthers alternately upon the orifice, and having dis- 

 charged their pollen, recede back to the petals. Linm. Stems un- 

 divided, with 5 sharp corners. Petals a little scolloped at the 

 ,edge, slightly nicked at the end ; white, with semi-transparent 

 greyish veins. Nectaries green, the globules yellow, from 10 to 

 15, generally 13. Stam. only half as long as the petals, at first 

 not longer than the germen, but each in order becomes longer 

 than the rest, as it sheds its pollen on the orifice of the germen, 

 which closes as soon as all the anthers have shed their pollen. 

 Root-leaves heart-shaped, on long leaf-stalks. Stem-leaves sitting. 

 Grass of Parnassus. Marsh Parnassia. Moist meadows in 



Wales and the northern counties. [Common in every boggy 

 meadow in Norfolk. Woodward. — Also in Staffordshire and 

 Worcestershire. Dr. Stokes.— Abundant in a meadow called the 

 Moor, at Blymhill. — On the tops of the high lands about Bux- 

 ton. Miss Sparrow.]* P. Aug. Sept.

Another striking confirmation of the remark that the same plants 

 may grow on mountains and in marshes, because the clouds resting on 



the tops of the mountains keep the air in a moist state, as is done by tiie 

 Jogs in meadows and marshes.
