(365.) E. subspathulata, C. M. & Kindb. (n. sp.)

E. spathulala, Canadian Musci, No. 421.

Monoecious. Stem very short, about 0.5 cm. high. Leaves bright green, spathulate or Ungulate, twisting when dry, the upper spreading when moist; inner basal cells short-rectangular, smooth and hyaline, finally red-brown, the outer ones very much longer, narrower and yellowish; costa faintly reddish below, yellow above, Iong-excurrent. Capsule cylindrical, short-necked, smooth or finally furrowed when dry; peristome pale, partly incomplete and membranose, but distinct and high; calyptra small, papillose in the narrower part, yellowish-green, not covering the whole capsule, not fringed; pedicel red.

Nearly allied to E. vulgaris but it has the peristome merely present. the calyptra longer, and the upper leaves not spreading. The true E, spathulata, C. Muell., has a shorter capsule without a peristome.

Quite common on boulders on the sides of ravines near the Fraser River, below Lytton, B.C., April 17th, 1889; on earth near McLeod's Lake, B.C. Lat. 55°. June 25th, 1875. (Macoun.)

(366.) E. leiomitra, Kindb. (n. sp.)

E. rhabdocarpa, Schw. var. leiomitra, Kindb. Ott. Nat. Vol. IV. 61.

Nearly allied to E. rhabdocarpa but differing in the leaves being shorter, often sub3pathulate, with the costa vanishing at the apex, peristomial teeth nearly blunt, calyptra not papillose, the spores larger.

On rocks along the Clearwater River, Athabasca. Lat. 57°. July 11th, 1888. (J. M. Macoun.)

(Macoun.) Rocks and banks amongst the Rocky Mountains. (Drummond.) Ounalaska and Kadiak Islands, Behring Sea, 1891. (J. M. Macoun.) Rocky ledges, Mount McKay, near Fort William and Kakabeka Falls, Lake Superior. (Mrs. Gr. E. Britton.) Greenland. (Fl. Gr.)

(368.) E, ciliata, Hedw.; Lesq. & James, Mosses of N. America, 182 Canadian Musci, No. 132.

Encalypta ciliata, Hedw., and E. Macounii, Aust., are very difficult to distinguish apart. The descriptions of the best authors are also not consistent. Schimper in synops. muscor. Europ. p. 343, says: "Peri-stomiumsiccitate capsulam horizontaliter claudens, humiditate patens;" Braithwaite, Brit. Moss-flora, p. 283, "peristome when dry horizontally closing the capsule, patent when moist;" Lesq, & James, Mosses of N. America, p. 182, "peristome spreading when dry;" Boulay, Muscinées de la France, p. 314, "dents du peristome dresseées a l'état sec, inflechies en voûte surbaissée a l'état humidc." It is probable that the authors are confounding both species, also occurring in Europe. E. ciliata. is principally found growing in the lower mountain districts. E. Macounii seems to be an alpine species also collected by Kindberg in the Norwegian,Alps and considered as a new species, E. borealis, Kindb.

Laubm. Schwed. & Norweg., but exactly agreeing with the original specimens of E. Macounii sent by Prof. Macoun. The description, made by Austin, cited by Lesq. & James, is, however, not completely exact: "calyptra densely papillose, pedicel reddish, papillose, the leaves muticous;" such characters are not to be found, the calyptra and the yellow pedicel are nearly smooth as in the true E. citiata, to which the descriptions of the peristome by Schimper and Braithwaite probably belong. The descriptions by Lesq. & James and Boulay could partly be referred to E. Macounii, although all authors agree in the description of the capsule of E. ciliata,"without a distinct collum"; E. Macounii has a distinct collum and the margin of the leaves distinctly reflexed. I possess no specimens of the true E. ciliata from North America. It may not occur there.

(369.) E. leiocarpa, Kindb. Bull. Torr. Bot. Club. XVII. 273.

Monoecious. Stem 3-4 cm. high, dichotomously branched, radiculose. Leaves erect-patent, Ungulate, faintly revolute nearly all around, without a hair-point; the lower decolorate brown, subacute, incurved; the comal larger, green, obtuse, slightly twisted; basal cells hyaline, the marginal very papillose; costa faintly papillose, not excurrent, in the lower leaves brown, in the comal green or reddish at the base. Perigonial leaves with a short thick tip. Capsule straight, smooth, cylindric with a short apophysis; peristome simple, orange; pedicel red; calyptra papillose all around, not fringed.
