—The cap/ule is fmall and quadrangular, with an afophyfis at the 
bafe: the ofercu/um is reddifh and flat, with a {mall point iffuing 
from its centre ; and the rim of the orifice is fringed with about fixty- 
four minute dents.—The exterior ca/ypira is conical, of a light ferru- 
ginous colour, and about double the length of the inner one. 
As this fpecies generally divides very low down, fingle branches 
of it may be carelefsly pulled up or feparated, in which ftate it may 
fometimes be confounded with the P. juniperinum ; but its being ra= 
ther fmaller in all its parts, its leaves being fhorter, ftiffer, more 
ereét and crowded towards the top of the branches, and its lower 
parts being generally matted together and enveloped in a whitifh 
downy fubftance, will eafily diftinguifh it. 
As neither the woolly calyptra nor the downy fubftance about 
the lower parts of the plant are expreffed in Vaillant’s plate, I have 
been induced to give a new figure of it, from a f{pecimen collected 
in Nova Scotia.

This is from two to four inches high, and generally naked to- 
wards the bottom, but covered with leaves, and often divided into 
two or three branches towards the top.—The /eaves are linear- 
Janceolate, with their edges turned in and finely ferrated, without 
any apparent middle nerve: when frefh they are of a dark green co- 
jour; but in a dried ftate they are contorted, and of a dull dark brown 
colour: they are rather thinly feattered on the ftalk, excepting here 
and there where they form tufts by being more thickly fet and fome-
