rounded with fpreading leaves, which are longer and more copious 

 at the termination of each year's growth and round the bafe of the 

 peduncles. — The leaves are long, fpreading, linear-lanceolate, and 

 ferrated with deep dents on their edges : in a dried ftate they are of a 

 reddifh-brown colour, and their edges turn in, fo as to give them a 

 round or fubulate appearance. — The peduncles are fhining, of a light 

 ftraw-colour, and from two to three inches long, irTuing out of a 

 tubular perichatium from the fummit of the ftalk ; but as a young 

 (hoot frequently iflues from near their bafe, the peduncle there- 

 by becomes lateral, and thus there are often two on the fame 

 ftalk, one terminal and the other lateral. — The capfule is oblong 

 nearly cylindrical, and fomewhat erect : the operculum is conical, 

 with a long (lender point turning fideways. — The exterior woolly 

 calyptra is wanting : the inner one, which is fmooth, fubulate, and 

 of a dark brown colour, is about three tenths of an inch long, with 

 a little roughnefs appearing about the point : as the capfule fwells 

 it fplits fideways from the bottom upwards. — The male rofaceous 

 cups are proliferous, and upon feparate ftalks, which in general pro- 

 duce ftronger and more crowded leaves. 



I was enabled to afcertain this plant by carefully comparing it 

 with the original fpecimen of P. magellanicum in the Linnean Her- 

 barium.
