(664.) E. acicularis, C. M. & Kindb. (n. sp.)

Tufts compact, brown-yellow or variegate with green. Stem much divided, very radiculose; branches very short and turgid, not attenuate. Leaves imbricate, with difficulty loosed from the stem, scarcely open when moist, finally golden-yellow, from the ovate-oblong base suddenly narrowed to a fine aciculiform or subulate point, denticulate nearly all around; cells not chlorophyllose, linear-lanceolate or fusiform, the alar not well defined; costa generally wanting. Barren.

On rocks in McKay's woods, near the lake, at Ottawa, May 2nd, 1885; also by an old lime-kiln at Brittania, six miles west of Ottawa, October, 1890. (Macoun.)

(665.) E. cladorrhizans, (Hedw.) C. Muell.

Neckera cladorrhizans, Drumm. Musc. Bor. - Am., No. 160, in part. Cylindrothecium cladorrhizans, Schimp.; Lesq. & James, Mosses of N. America, 311; Canadian Musci, No. 263.

Entodon (Cylindrothecium) cladorrhizans Hedw., differing from the European E .Schleicheri (Schimp.) in the broad annulus of the capsule which is very imperfectly described by Lesq. & James (page 311.) It merits therefore a more complete description of the plant.

Tufts dense but loosely cohering. Stem pinnate; branchlets alternate. Leaves ovate-oblong, obtusate with a very short, often recurved point, subentire or slightly denticulate above, often faintly striate; margins recurved at the angles; cells not distinctly chlorophyllose, narrow, fusiform-lanceolate or sub-linear, also the inner basal; alar cells numerous, well-defined and quadrate; costa none or short and double. Perichetial leaves long subulate-acuminate, faintly denticulate at the acumen. Monoecious.

On logs, Tay, York Co., KB. (J. Moser.) On old logs in McKay's woods at Ottawa; very abundant on old logs at Carleton Place, 30 miles west of Ottawa; on stones at Britannia, six miles west of Ottawa; common on old logs at Belleville, Leamington and Owen Sound, Ont. (Macoun.) Trunks of trees, Upper Canada (Ontario). (Drummond.) Common on old logs at London, Ont. (J. Dearness)

(661.) E. Macounii, C. M. & Kindb. (n. sp.)

Cylindrothecium Drummondii, Canadian Musci, No. 436.

Tufts loose. Stem sparingly divided, translucent (visible, in a dry state, through the leaves); branches much compressed, elongate, not attenuate, shining green above. Leaves patent, concave, short, ovate-lanceolate, attenuate to a short subulate point; basal angles rounded; margins scarcely recurved below, faintly denticulate all around; cells faintly chlorophyllose, long-sublinear, the lowest basal dilated, oblong or the alar often subquadrate; costa none or very short and double. Perichetial leaves small, convolute or connivent, longer acuminate, more distinctly denticulate at the apex. Dioecious.

The species is quite distinct; Entodon Drummondii differs in the leaves being obtusate, nearly entire, etc.

On earth in the "Big Swamp," Murray, Northumberland Co., Ont., October 7th, 1888. (Macoun.)

(668.) E. (Raphidostegium ?) expallens, C. M. & Kindb. (n. sp.)

Tufts loose, pale yellow. Stems sparingly divided, radiculose at the base. Branches elongate, much compressed, not attenuate. Leaves sub-distichous, patent, short ovate-lanceolate, acute, concave, nearly entire, denticulate only at the apex, distinctly auriculate, not recurved at the margins; cells not chlorophyllose, long-sublinear, the inner basal dilated sub-oblong; auricles excavate, well-defined with large, oval or roundish, finally golden-yellow cells; costa none or double, sometimes reaching to the middle. Barren.

This species could perhaps be related to the genus Raphidostegium, but the leaves are not recurved at the margins; the plant is more robust and resembles Entodon Macounii in habit.

In boggy soil in wet woods at Stephen, summit of Rocky Mountains, July 23rd, 1885. (Macoun.)
