On the bases of trees, North Arm, Burrard Inlet, B.C., April 29th, 1889; also at Sicamous, B.C. (Macoun.)

(740.) B. leucoglaucum, C. M. & Kindb. (n. sp.); Canadian Musci, No. 591.

Tufts loose with few rhizoids, whitish or subglaucous-green, faintly shining. Stem sub-pinnate or irregularly branching. Leaves from the ovate base suddenly tapering into a somewhat long-filiform, often half-twisted, point, sharply serrate above, faintly denticulate below, striate, decurrent, borders reflexed below; alar cells small, numerous, the others narrow; costa long, sometimes subpercurrent. Perichetial leaves long, filiform-acuminate, arcuate-squarrose. Capsule curved, oblong-cylindric; lid subobtuse when moist; pedicel faintly rough, about 1.5 cm. long; peristome conic-connivent, teeth serrulate, pale above, segments open in the middle, papillose above, cilia not appen-diculate. Monoecious. Intermediate between Brachythecium Rutabutum

4/ and B. curtum.

On loose earth at Canaan Forks, Queen's Co., and Elmwood, King's Co., KB., September 10th, 1888. (J. Moser.)

(741.) B. rutabuliforme, Kindb. (n. sp.)

Agrees with Brachythecium Rutabulum in the very rough pedicel, the monoecious inflorescence and the form of the leaves; differs principally in the rigid stem, the distinctly appendiculate cilia of the peristome and the short pedicel, about 1 cm. The leaves are subovate, short-acuminate, nearly estriate and faintly denticulate.

Growing on stones in a brook north of Spence's Bridge, B.C., May 30th, 1889. (Macoun.)

(742.) B. Columbico-rutabulum, Kindb. (n. sp.)

Tufts dense, faintly shining, finally brownish-green. Stem elongate, pinnate, creeping. Stem-leaves patent, from the broadly ovate base long-cuspidate with a filiform, generally prolonged point, decurrent, very plicate, nearly entire, borders shortly reflexed below; cells not chlorophyllose, the alar larger and well-distinct. Perichetial leaves suberect-patent with a long, filiform, arcuate point, faintly and distantly denticulate. Capsule oblong-cylindric, curved; peristomial teeth not serrulate, segments very open in the middle, cilia faintly nodulose, not appendiculate; pedicel very rough, about 2 cm. long. Monoecious.

This species resembles Brachythecium spurio-rutabulum in habit, but the leaves are still more plicate and nearly entire; the pedicel also is longer. It differs from Brachythecium Butabulum only in the very plicate leaves, etc.

On very wet and rotten logs in woods along the Columbia River about one mile above Revelstoke, B.C., May 13th, 1890. (Macoun.)

(743.) B. lamprochryseum, C. M. & Kindb. (n. sp.)

Tufts large, laxly cohering to the substrate with few rhizoids, golden-yellow, shining or finally decolorate. Stem elongate, often pinnate; branches generally short or sometimes more elongate and faintly curved above, subacute. Leaves open, more or less loosely disposed, long-decurrent, distinctly auriculate, very plicate, from the triangular-ovate base short-acuminate, filiform or subulate-cuspidate, often curved at apex, nearly flat, only the auricles faintly revolute; borders faintly denticulate all around; most of the cells long and very narrow, the lowest basal ones dilated and short, also the alar, all very sparingly chlorophyllose; costa broader at the base, faint, reaching to the middle, but in the smaller narrower and more loosely disposed leaves of some branchlets longer, reaching to the acumen. Capsule short, sub-ovoid, thicker near the base, slightly contracted below the mouth, arcuate; lid unknown; teeth finally brown at least at the base; cilia not appendiculate; pedicel very rough, about 3 cm. long. Perichetial leaves nerveless, when dry squarrose, the inner sheathing with a short, subulate acumen and a long, filiform point. Monoecious.

Allied to Brachythecium Butabulum, but distinct in the nearly plane (not concave), auriculate, long-decurrent and very plicate leaves.

On stones, Mount Finlayson near Goldstream; on Mount Benson near Nanaimo and at Comox, Vancouver Island, 1887. (Macoun.)

(744.) B. mirabundum, C. M. & Kindb. (n. sp.)

Tufts large, very laxly cohering, nearly without rhizoids, silky or yellowish-green, faintly shining. Stem elongate, irregularly divided or prolonged, into sciuroid-curved, obtuse branches. Leaves loosely imbricate, crowded, when dry subrugose, when moist patent, short-decurrent, indistinctly auriculate, faintly plicate, from the concave, ovate and gradually acuminate base long-cuspidate; borders broadly recurved at least at one side of the nearly entire base to the involute and distinctly denticulate acumen; cells pale, elongate, and narrow, the alar subquadrate and not much wider than the other basal ones, all sparingly chlorophyllose; costa vanishing in the acumen. Capsule small, at the base indistinctly gibbous, narrow, cylindric, and curved; lid elongate-conic; pedicel very short, 0.5-0.8 cm., very faintly muriculate. Perichetial leaves nerveless, longer filiform-cuspid ate, irregularly sinuolate, the point patent or arcuate; basal cells larger, rectangular; archegonia numerous, about 20. Monoecious.

This species is allied to Brachythecium Rutabulum, differs principally in the minutely muriculate and short pedicel of the small, narrow capsule, also in the leaves.
