The adoption of the genus A nisothecium enables us to retain the specific
name crispum for this plant, which otherwise would have to give way to
Dickson's and be termed D . vaginalis, for Dicranella Schreberi was named
crispum seventeen years before the present plant was known.

D io ico u s ; slender, laxly cæspitose, dull yellowish-green; leaves
from a shorter semivaginant ovate base, setaceous, falcato-secund,
channelled, minutely denticulate at a p e x ; cells elongated, v ery narrow
toward margin ; perich. bracts thinner and with longer lamina. Capsule
on a pa le red seta, erect or a little inclined, ovate-oblong, equal, pale
brown, annulate, striate ; lid, peristome and male plant as in D . secunda.

Greenock (Drummond Brit. Mosses 115).
Very close to the preceding and probably often confounded with it ;
in Europe it appears to be confined to the more southern portion of the
central part.
