On sterile banks, moors, thatched roofs, and where heath has been
burned ; not unfrequent. Fr. Spring.—A very distinct and well-marked

from Nepal almost exactly resembles this, except in being thrice
its size.

5. D. glaucescens, Web. et Mohr, {glaucous Didymodon);
stems rather short densely tufted slightly branched, leaves
linear-lanceolate erecto-patent acute remarkably glaucous, capsule
oblong erect, lid conico-rostrate. Fl. Cr. Germ. p. 158.

Scottish mountains, very rare. Glen of the Dole, Clova, on rocks
slightly covered with earth. Fr. Aug.—Distinguished at once by its
glaucous-green hue. The peristome is long, red, consisting of 32 filiform
teeth, placed in pairs.
6. D. Brwitoni, Am. (Mr. Bruntons Didymodon); stems
elongated pulvinate branched, leaves lanceolato-subulate the
margins slightly recurved scarcely serrated twisted when dry,
capsule erect ovate, lid obliquely rostrate. Am. Disp. Muse.

I Rocks, in alpine districts. Fr. June.—This has very much the habit
of Wcissia crispula ; but the peristome is truly that of a Didymodon. It
has been well illustrated in the beautiful Scottish Cr. Flora, by Dr.
Greville, who finds it abundantly on the Pentland hills, as Mr. IT.
Wilson does at Aber, N. Wales. The latter observes a slight appearance
of a struma at the bottom of the capsule.
7. D. rigidulus, Hedw. (rigid-leaved Didymodon); >teni>
elongated branched, leaves lanceolate carinate tapering upwards
to a narrow point the margins reflexed entire, nerve
rigid running beyond the point, eapMile oblongo-ovate erect,
lid rostrate. WUs Hedw. St. Cr. r. :). t. 4. Muse. /int. ed. 2.

Walls and rocks. Fr. Sept. to March.—Mr. Turner well observethat
the foliage ofthia moss much resemble! that of TorhtlafaUax: but
the nerve i> different, singularly rigid, of a brown colour (as well as tinleaves
themselves), ami aecidedlv running out beyond the point o\ the
leaf: thus the sterna have a bnstrj appearance from the ituthess and
Bharpnesa of the foliage. Near Beaumaru Mr. Wilson baa observed
a var. with a cylindrical capsule.
