1 1. O. Hutehinsice, Sm. {Miss Hutchins Bristle-Moss); stems
erect, leaves lanceolate erect rigid, capsule clavate furrowed,
calyptra very hairy. E. Bot. t. 2523. Hobs. Br. Mosses, v. 2.

On rocks in alpine situations, in England, Scotland and Ireland:
first discovered in the latter country by Miss Hutchins, near Bantry.
Fr. May.— This has the capsule of O. crispum, but the foliage more resembling
that of O. anomalum, of a blackish-brown colour, and as erect
when dry as it is when moist. Seta often twisted. Peristome with its 8
teeth, when recurved, deeply and regularly cleft down the middle.
12. O. Ludwigii, Brid. (Ludwigian Bristle-Moss); stems creep-
ing, leaves erecto-patent narrowly lanceolate crisped when dry,
capsule pyriform smooth furrowed only at the extremity, mouth
extremely contracted, calyptra remarkably hairy. Brid. Muse.
Suppl. p. 26. Schwaegr. Suppl. v. 1. P. II. p. 24. t. 51.

Frequent on young oaks, in subalpine glens, in various parts of Scotland.
Fr. Aug.—The capsule may distinguish this, at first sight, from
every other Orthotrichum. The innerfringe of the peristome is exceed-
ingly fugacious.

leaves lanceolato subulate much crisped when dry, capsule
oblongo- clavate furrowed, teeth of the peristome 8 geminate

14. O.pulcMllum, Sm. (elegant Bristle-Moss); stems creeping
short, leaves narrow-lanceolate crisped when dry, teeth of

—This is an exceedingly beautiful species and well deserves the name
which Smith has given it. The capsule, Mr. Wilson observes, is very
generally tuberculated.
