quandoque solitarias, saepe tres ad sex ex eodem caule, versus
ejus medium inserta;, subbiunciales, erectas, flexuosae. Capsula
ovata, erecta. Operculum { f . 5) rostratum, rostro recto, capsula

Among the Neckerce none of the hitherto described species
will accord with that here figured, nor will any of those belonging
to Leskea, a genus to which it has an almost equal claim.
The plant of all others to which it approaches the nearest in
general habit, is doubtlessly Climacium dendroides {Hypnum
nobis) ; and even in its peristome it is not far removed, for the
teeth of the inner fringe are perforated, but not so remarkably
as in that plant; and the columella, it may be observed, is not at
all exserted.

or less magnified.
