C'OMMUNICATED by Mr. Dickson, who assures us it
is a native of high rocks; rather than of trees or heathy ground,
as Mr. Hudson indicates; which circumstance, and his misapplication
of synonyms, lead us to believe that this author,
if he knew the present moss at all, confounded it with G.
Dicksoni, t. 1420.
The two species are very much alike in habit, but the
leaves of the cirrata are of a more yellowish green and much
narrower. The essential distinction however resides in the
capsule, which is shorter, ovate, with a wide mouth, very
different from the peculiarly narrow orifice of G. Dicksoni.
The fringe is injured in our specimens, being very brittle.
Since the Flora Britannica was published, Mr. Dickson has
favoured us with numerous young capsules, in which the lid
is long and slender, nearly equal to the capsule itself. Dr-
Abbot’s Bryum cirratum proves to be G. Dicksoni.
