nearly a quarter of an inch long, which clofely furround their bafe. 

 — The capfule is fmall and quadrangular, with an apophyfis at the 

 bafe : the operculum is reddifh and flat, with a fmall point ifTuing 

 from its centre ; and the rim of the orifice is fringed with about fixty- 

 four minute dents. — The exterior calyptra 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 careiefsly pulled up or feparated, in which flare it may 

 fometimes be confounded with the V. juniper inum; but its being ra- 

 ther fmaller in all its parts, its leaves being fhorter, rtiffer, more 

 ere& and crowded towards the top of the branches, and its lower 

 parts being generally matted together and enveloped in a whitiOi 

 downy fubftance, will eafily diftinguifh it. 



As neither the woolly calyptra nor the downy fubftance about 

 the lower parts of the plant are exprefTed in Vaillant's plate, I have 

 been induced to give a new figure of it, from a fpecimen 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 leaves are linear- 

 lanceolate, with their edges turned in and finely ferrated, without 

 any apparent middle nerve : when freih they are of a dark green co- 

 lour ; but w a dried ftate they are contorted, and of a dull dark brown 

 colour : they are rather thinly fcattered on the ftalk, excepting here 

 and there where they form tufts by being more thickly fet and fome-
