(454.) B. arcticum, Bruch & Schimp.; Lesq. & Jaines, Mosses of N. America, 224.

(455.) B. erubescens, Kindb. (n. sp.)

Stems short, scarcely 1 cm. high, loosely tufted. Leaves of the innovations green and small; stem-leaves few, red-brown, not decur-rent, ovate-lanceolate acuminate, red-margined, not revolute at the entire borders; areolation pellucid, decolorate, upper cells narrow-rhomboidal or hexagonal; costa red, more or less excurrent; inner perichetial leaves smaller, immarginate, slightly sinuolate above with a percurrent costa. Capsule small, regular, pendent, narrow-oblong, constricted below the mouth; cilia appendiculate; lid convex, mammil-late; pedicel thin, pale red, 2-3 cm. long. Spores extraordinarily large, about 0.08 mm. Dioecious.

This species having the habit of a Webera (W. acuminata or W. polymorpha), has no affinity to the other Eubrya, found in Canada. The small reddish leaves and the large spores distinguish it at once. It grows mixed with Amblystegium porphyrhizon.

On the roots of a turned-up tree close to the discharge of Lake Louise, Rocky Mountains (No. 178). August 18th, 1891. (Macoun.)

(456.) B. hsematophyllum, Kindb. (n. sp.); Canadian Musci, No. 555.

Stems short, about 1 cm. high, loosely tufted or solitary. Leaves small, red, densely crowded, not decurrent, ovate or ovate-oblong, acute, indistinctly margined, reflexed at the entire borders; areolation red, nearly uniform and loose; costa very broad, not, or very short, excurrent; perichetial leaves oblong-lanceolate. Capsule (not ripe) regular, pendent, obovate; lid convex, short-apiculate; pedicel thin, 1-2 cm. long. Spores small. Dioecious.

This species, probably belonging to the section Eubryum, is peculiar in the thick and broad costa of the red and short leaves.

On wet rocks in the "Dry Canon" near the discharge of Devil's Lake, Rocky Mountains (No. 104). August 10th, 1890. (Macoun.)

No. 164, collected in the same locality seems to belong here, but the single unripe capsule has a mammillate lid.

(458.) B. subpurpurascens, Kindb. (n. sp.); Canadian Musci, No. 593.

Agreeing with B. purpurascens in the red tufts, the elongate shoots, the costa scarcely or faintly excurrent, the capsule long-necked, constricted below the mouth, teeth orange-colored, segments free, cilia smooth, spores small, lid large, mammillate, pedicel red; differs in the inflorescence being dioecious, all leaves red-margined, long-excurrent, and principally in the curved subclavate capsule, resembling that of Bryum meeseoides.

Differs from B. pendulum in the leaves being narrow, ovate-lanceolate, reflexed all around; upper areolation very narrow, sub-linear, basal cells reddish; costa red. Capsule sub-cylindric; pedicel arcuate above; teeth paler; spores small, scarcely 0.02 mm. Syncecious.

Habit of Webera nutans. Agrees with Bryum inclinatum in the synoecious inflorescence and the symmetric capsule, etc, differs in the leaves being long-acuminate, cells long and narrow, the upper sublinear (nearly as in Webera), costa very long-excurrent, peristomial segments quite free from the teeth, spores smaller, scarcely 0.02 mm.; the cilia are wanting.
