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 (hoots iffue from their bafe, 

 they afterward become lateral.— The capfule is cylindrical and fome- 

 what ereft, having a ftrong annulated rim fringed with about thirty- 

 two minute dents : the operculum is conical and pointed. — The ex- 

 terior calyptra is fmall, of an oval form, and of a light draw colour, 

 and is about twice the length of the inner one. 



This fpecies 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 diftinclion.

The Jlalk of this fpecies appears reddifh, and is generallv flightly 

 branched, though not unfrequently met with fingle, and grows from 

 an inch to two inches in height —The leaves are obtufely lanceolate, 

 and finely ferrated on the edges, with the middle nerve dentated on 

 the back of each : thole on the upper parts of the ftalk and branches 

 are of a dark glaucous colour, changing in the dried ftate to a dull 

 blackiih hue ; but the lower leaves, and the bales of the upper ones, 

 arc reddiih* and become whititti when dried; they are generally 

 larger and more crowded at the top and at the divifions of the 

 branches.— The peduncles very i'eldom exceed three in number, and
