Dioecious. Plants robust, laxly caespitose, 3-10 cm. high, black at the base, fuscous-green above. Leaves very long, elongate-lanceolate from a broader base, margins revolute below, gradually attenuated into a smoothish hair, basal cells narrow, upper short, more or less papillose, all slightly sinuose. Capsule ovate 10-striate, when dry, oblong, pale-brown; calyptra lobate; annulus of 3 rows of cells; lid rostellate or sub-acicular; teeth purple; pedicel short, pale, arcuate.

(Macoun.)

(263.) C. depilata, Kindb.

G. densa, Kindb., Bull. Torr. Bot. Club, XVIL, 271.

Tufts large and compact, brown or green above. Stem elongate. Leaves, when moist arcuate, ovate-lanceolate (shorter than in G. trichophylla), recurved on both sides, generally hairless and obtuse, sometimes with a short hair-point; alar cells hyaline elongate in 4 5 rows, the other more or less erose. Perichetial leaves from the sheathing base narrowed into a longer, canaliculate, sublinear (not subulate) and obtuse acumen. Capsule nearly smooth, when dry finally rugose, not distinctly costate; teeth red, deeply cleft below the middle, when dry, spreading, connivent when moist; beak more or less oblique; pedicel arcuate when dry.

This species is nearly allied to Grimmia trichophylla and very critical but is approved of by Dr. C. Mueller.

Summit of Mount Benson, near Nanaimo, Vancouver Island, alt. 3,000 feet; June 8th, 1887. (Macoun.)

(264.) C. Olneyi, Sulliv.; Lesq. & James, Mosses of N. America, 142.

(265.) C - arcuatifolia, Kindb., Bull. Torr. Bot. Club, XVI., 93.

Loosely tufted; tufts blackish, dark green above. Stems 5 cm. long, denudate at base. Lower leaves small, upper long and not crisped; hooked-curved when moist, ovate-lanceolate, long-acuminate and acute, reflexed at least at one border with a short denticulate hair-point; most of the basal cells pellucid, long and narrow, the upper basal cells sinuous, the marginal uniseriate and hyaline or not distinct; the other cells chlorophyllous, quadrate and not sinuous; costa per-current canaliculate, pellucid in the middle.

Probably allied to the European Grimmia elatior, Bryol, Europ., but this species has also the upper cells sinuous.

Abundant on dry rocks, Cedar Hill and Mount Tolmie, near Victoria, Vancouver Island, April 21st, 1887. (Macoun.)

(266.) C. microtricha, C. M. & Kindb. (n. sp.)

Plants in small blackish pulvinate tufts with green tops. Leaves, when moist, suberect, short ovate-lanceolate, margins recurved, plane only at the short base; cells short, the alar narrow and hyaline. Perichetial leaves ovate obtuse. Capsule oblong, smooth; teeth dark red; annulus not distinct; lid short conic, obtuse; calyptra narrow, dimidiate; pedicel flexuous, about 3 mm. long. Dioecious or monoecious on distinct branches.

Differs from the allied Grimmia alpestris principally in the longer emergent capsule, the recurved leaf-margins and the short perichetial leaves.
