B. murale, Canadian Musci, No. 186.

Nearly allied to B. erythrocarpum; differs in the shorter stem; the leaves distinctly yellow-margined, laxer areolate, the costa sometimes excurrent, the capsule more ventricose, constricted below the mouth, the lid longer-apiculate.

(490.) B. haematocarpum, C. M. &Kindb. (n. sp.); Canadian. Musci, No. 555.

Tufts very tomentose below the green innovations, about 5 cm. high. Leaves loosely appressed, when dry slightly corrugate but not twisted, crowded, not decurrent, subovate, acute, pellucid, narrow-marginate and revolute at the entire borders all around, those of the innovations less distinctly revolute and marginate to above the middle; cells pale yellow, the upper short-rhomboidal; costa yellow, percurrent or in the upper-most leaves slightly excurrent. Capsule large (as in Bryum pallescens), suboblong-cylindric, blood-red, doubly longer than the pale collum, pendent or patent, not appressed to the pedicel; peristome dark-yellow or orange below, pale above; segments free and very much shorter than the membrane; cilia faintly appendiculate or rather nodose; annulus broad; lid nearly flat and apiculate; pedicel red, flexuous, about 2-5 cm. long; spores small, about 0.018 mm. Dioecious.

This remarkable species is a true Eubryum, although the peristomial cilia are not distinctly, or only at the base, appendiculate. It resembles Bryum alpinum in the color of the capsule, but is very different in the shorter, margined leaves and their wider areolation, the tomentose tufts, etc.

On damp rocks on the mountain between Pass Creek and the Columbia River above Sproat, June 19th, 1890. (Macoun.)

(491.) B. pygmaeo-alpinum, C. & M. Kindb. (n. sp.)

Tufts dense and small, about 1 or 1.5 cm. high. Stem sparingly radiculose to the buds. Leaves small, olive-green or finally reddish, flaccid, not glossy, laxly areolate, hyaline; the uppermost close, the other loosely disposed, not decurrent, very much smaller, all subovate or oval obtuse, the uppermost sometimes subacute; borders not margined nor revolute; upper cells short-rhomboidal; costa broad, purplish, percurrent or in the uppermost leaves slightly excurrent. Barren.

This species is probably allied to Bryum calophyllum or to Bryum obtusifolium, Lindb. On wet rocks, summit of Mount Arrowsmith, Vancouver Island, alt. 5,700 feet, July 17th, 1887. (Macoun.)

(492.) B. percurrentinerve, Kindb.

B.percumcentinerve, Kindb., Bull. Torr. Bot. Club. XVII., 274; Canadian Musci, No. 505.

Tufts compact, dull green above, decolorate below, about 2 cm. high. Leaves, when dry, appressed and corrugate, when moistened sub-patent, crowded and slightly decurrent, ovate obtusate (only the uppermost ovate-oblong and subacute), narrow-margined and revolute at the entire borders to the greater part; areolation pellucid, upper cells wide, sub-rhomboidal; costa red and percurrent, in the uppermost leaves pale.
