what longer at the termination of each year’s growth.—The peduncles 
are from an inch to an inch and half long, and arife out of a va- 
ginal tube about a quarter of an inch in length, at the extremity of 
each year’s growth; but as the young fhoots iffue from their bafe, 
_ they afterward become lateral.—The cap/ule is cylindrical and fome- 
what erect, having a {trong annulated rim fringed with about thirty- 
two minute dents: the operculum is conical and pointed.—The ex- 
terior calypirais {mall, of an oval form, and of a light ftraw colour, 
and is about twice the length of the inner orie. 
This f{pecies very much refembles P. convolutum, but that has al- 
ways a fimple ftalk with a fingle terminating peduncle, and its leaves 
are only flightly ferrated towards their tips; whereas this, even in 
its fimple ftate, has generally two or three lateral peduncles, and the 
leaves are finely ferrated their whole length, which will afford fuffi- 
cient marks of diftinétion.
