This species has the habit of Bryum Warneum, also in the shape of the capsule, but it is a true Eubryum with appendiculate cilia.

On earth, near London, Ont. 1889. (J. Dearness.)

(501.) B. oligochloron, C. M. & Kindb. (n. sp., ad interim); Canadian Musci, No. 554.

This species is still doubtful, being only found in a barren state. It is peculiar in the upper leaf-cells being very narrow (as in the section Anobryum), the leaves are ovate-lanceolate, long-acuminate, nearly hyaline and the costa long-excurrent.

On rocks at Deer Park, Lower Arrow Lake, Columbia River, B.C., June 12th, 1890. (Macoun.)

(502.) B. rubicundulum, C. M. & Kindb. (n. sp.); Canadian Musci. No. 519.

Tufts compact, olive green, very radiculose to the innovations. Stems about 2-3 cm. high. Leaves appressed when dry, concave, obtuse, the lower oblong, the upper ovate, forming small buds, chlorophyllose and not yellow nor hyaline, rarely reddish; borders revolute and narrow-marginate nearly all around: upper cells wide; costa red, subpercurrent; perichetial leaves narrower, sub-acute and narrow-areolate. Capsule inclined, obovate-oblong, short-necked, constricted below the mouth when dry, purplish-brown; peristome pale-yellow; inner membrane low; cilia short, nodulose or appendiculate; spores small, about 0.016 mm.; lid conical, short-apiculate; pedicel geniculate at the base. Dioecious.

This species is nearly allied to B. miniatum but the stems are more radiculose and very much less foliate, the leaves rarely purplish, and their areolation wider. The capsule of neither species is larger than in Bryum caespiticium, smaller than in Bryum Atwateriae. The leaves in Bryum percurrentinerve are larger and bright green.

On the summit of Hermit Mountain close to the glacier on the west side, Roger's Pass, Selkirk Mountains, B.C., August 5th, 1890. (J. M. Macoun.)

(503.) B. anoectangiaceum, C.fM. & Kindb. (n. sp.)

Tufts compact, radiculose, small, scarcely 2 cm. high. Leaves small, rose-colored, loosely disposed, not decurrent, spirally contorted in a dry state, ovate-acute, pellucid, narrow-marginate, entire, faintly revolute, laxly areolate; costa thick, reddish, percurrent or short-excurrent. Probably monoecious, but the male flowers not well developed.

This peculiar species is perhaps nearly allied to Bryum erythrophyllum On rocks by the torrent at Hector, Rocky Mountains, B.C., August 12th, 1890. (Macoun.)

Differs in the leaves being finally purplish-colored, less contorted when dry, distinctly serrate above, finally red-margined, the costa dark-purplish, either long-excurrent, with the point thick and very rigid, or vanishing below the apex. Dioecious.

It agrees also with Bryum Donianum, Grev., in the clavate branches and the smaller spores, about 0.01 mm., but the leaf-borders are not incrassate, the capsule is not so large. On earth in McKay's bush, iwar-Ottawa, Ont., (1888); on earth at Hastings, Burrard Inlet, B.C. (1889); on rocks at Esquimalt, Victoria and Nanaimo, Vancouver Island; also on Mount Erskine, Vesuvius Bay, Salt Spring Island, Gulf of Georgia (1887). (Macoun.)

(508.) B. erythrophyllum, Kindb. (n. sp.)

Closely allied to the arctic Bryum obtusifolium, Lindb. Barren stems laxly cohering, blood-red, about 1 cm. high. Leaves small, reddish, loosely disposed, flaccid, not decurrent, the lower ovate, subobtuse, the upper leaves sometimes more attenuate, furnished with a rigid point to the excurrent costa, entire, subimmarginate, not reflexed at the margins; areolations lax, nearly uniform; costa red, percurrent or slightly excurrent in a short recurved point.
