Dioecious. Tufts loose, purple, without rhizoids. Stems about 1 cm. high, branches not divided. Leaves nearly straight, loosely appressed when dry, patent when moist, short ovate-lanceolate attenuate, acute, papillose; margins faintly revolute at the base, also above at least on one side; costa red, subpercurrent; basal cells rectangular pellucid, the other subquadrate, dusky. Barren.
On earth subject to inundation one and a half miles above Revelstoke, along the Columbia River, B.C., May 12th, 1890. (Macoun.)
North West Coast. (Douglas.) I believe Douglas' specimens to be B. robustifolia, C. M. & Kindb. (Macoun.)
On rocks, Deer Park, Lower Arrow Lake, Columbia River, B.C., June 11th, 1890; on damp rocks at Spence's Bridge, Yale, and Agassiz, B.C.; also wet rocks, Cadboro Bay, Vancouver Island. (Macoun.)
(211.) B. robustifolia, C. M. & Kindb. (n. sp.) Barbula rubiginosa, Canadian Musci, No. 75.
Very nearly allied to Barbula tortellifolia. Differs in the dark brown or olive-green color of the whole plant, the leaves being more crowded, shorter with an ovate-oblong base, borders reflexed nearly to the middle at one side, upper cells larger and sub-pellucid, the basal ones hyaline subquadrate, costa thicker and not excurrent, linear and distinct to the apex. Barren.
Abundant on rocks at Cedar Hill and other localities near Victoria; also on rocks on Mount Erskine, Salt Spring Island, Gulf of Georgia, B.C. First collected at Victoria, May 5th, 1875, and then named B. rubiginosa by Austin. (Macoun.)
(212.) B. tortellifolia, C. M. & Kindb. (n. sp.)
Barbula cylindrica, Canadian Musci, No. 81, in part. B. flexifolia, Canadian Musci, No. 399. ,
This species very much resembles Barbula horridifolia in its habit but is found in a well-fruiting state. It is generally more robust, often 4-5 cm. high and finally sometimes quite red. The stem is more divided, the leaves broader, less distinctly decurrent, the comal ones larger and crowded, short-pointed by the excurrent costa; the perichetial ones suddenly attenuate to a long narrow acumen, but the costa is faintly excurrent. The capsule is large sub-cylindric, reddish doubly longer than the beak; peristome long, once loosely contorted whitish. Dioecious.
On wet rocks on the North Arm, Burrard Inlet, B.C.; on rocks by the sea, Telegraph Bay, near Victoria, Vancouver Island; also on rocks by the sea, Vesuvius Bay, Salt Spring Island, Gulf of Georgia, B.C. (Macoun.)
(213.) B. circinnatula, C. M. & Kindb. (n. sp.)
Nearly allied to Barbula cylindrica or rather intermediate between Barbula elata and B. virescens. Differs in the upper leaves being green, circinnate-twisted in the dry state, the peristome paler and the annulus simple; the areolation of the leaves is also more distinct.
On earth on rocks along the railway a mile east of Agassiz, B.C., May 8th, 1889. (Macoun.)
(214.) B. horridifolia, C. M. & Kindb. (n. sp.)
Densely tufted. Plants about 3 cm. high, green above, rusty-red below, more or less branching. Leaves dry irregularly crispate, when moistened falcate, spreading at all sides, very long and narrow, ovate-lanceolate, carinate above, loosely disposed and long-decurrent, nearly smooth; borders reflexed at the ovate base; basal cells pellucid, short-rectangular, the inner larger; upper cells small and obscure; costa red-brown, broader below, narrower above, vanishing in the apex. Barren.
This species is allied to Barbula cylindrica (Tayl.) Lindb., but differs principally in the decurrent leaves and the attenuate costa.
On damp rocks, near the whirlpool, west of the Columbia River, at Revelstoke, B.C., May 9th, 1890. (Macoun.)
(215.) B. convoluta, Hedw.; Lesq. & James, Mosses of N. America, 127; Canadian Musci, No. 76.
Tortula convoluta, Drumm. Musc. Bor. - Am., No. 138.
Sandy soil in the country extending from Canada to the Rocky
.Mountains. (Drummond.) On pasture fields and by roadsides at
Ottawa, Carlton Place, Belleville, Niagara Falls and Owen Sound,
Ont.; on earth at Victoria and Comox, Vancouver Island. (Macoun.)
On earth, very common at London, Ont. (J. Dearness.)
(216.) B. chrysopoda, C. M. & Kindb. (n. sp.)
Differs from Barbula convoluta in the short nearly indistinct stem, the leaves sub-lingulate, very obtuse, the perichetial leaves rounded or truncate at the apex, long exserted, the lid spirally contorted.
On earth in the burnt woods around Revelstoke; especially along old roads, May 17th, 1890. (Macoun.)
