Crevices of rocks, St. John, N.B. (Fowler's Cat.) (431.) W. polymorphoides, Kindb. (n. sp.)

Tufts large and dense, dull green above, rufescent below, 4-5 cm. high. Stem finally denudate at the base, radiculose in the middle. Leaves crowded, not decurrent, ovate-oblong, acute or subobtuse, widely areolate, nearly entire and flat at the borders with the costa vanishing below the apex; the comal ones longer, sublinear-lanceolate short-acuminate with the upper cells narrow, the borders reflexed to the greater part; the costa thick and sub-percurrent. Capsule oblong, short-necked, pendent; peristome pale-yellow, segments with a narrow basal membrane, cilia short and rudimentary; annulus narrow; lid mammillate; pedicel about 2 cm. long; spores brown, about 0.02 mm.

This species is allied to Webera polymorpha, but is very much larger, in habit resembling Webera longicolla.

Allied to Webera nutans. The median and comal leaves are longer-attenuate, denticulate sometimes below the middle, narrow-areolate, their costa is thick, canaliculate and excurrent; the comal ones revolute at the borders; only the lowest shorter and short-decurrent; the peristome is pale; lid low and flat.

(437.) W. subcucullata, C M. & Kindb. (n. sp.)

W. gracilis, Canadian Musci, No. 424.

This species which has the habit of Mielichhoferia nitida, seems to be intermediate between Webera cucullata and Webera pycno-decurrens. It resembles the last in the small compact tufts, the geniculate pedicel and the dioecious inflorescence, the small, (unripe; short-necked capsule, and the mammillate lid; but the stems are subjulaceous, and the dull green leaves are densely crowded and not decurrent; the lower leaves are short and subobtuse, nearly as in Webera cucullata but the areolation is narrower.

(438.) W - pycno-decurrens, C. M. & Kindb. (n. sp.)

Tufts dense, glossy bright green, 1-1.5 cm. high. Fertile stem 0.3-0.5 cm. high. Leaves small, acute, the lower ovate-oblong, crowded but short-decurrent, the comal very much longer, sublanceolate, revolute at the borders for the greater part, denticulate above, the inner perichetial leaves very much shorter, looser areolate; costa not excurrent. Capsule obovate, red-brown, distinctly short-necked, annulate, orange-margined at the mouth; cilia sometimes appendi-culate, inner membrane broad, teeth finally dark yellow; lid convex, orange-margined, mammillate; pedicel geniculate at the middle; spores brown, small, about 0.01 mm. Dioecious. This species resembles Webera commutata or rather Webera Lescurii, but seems to be quite distinct.

On earth amongst rocks, near perpetual snow on the Gold Range, north of Griffin Lake, B.C.; alt. 7,000 feet. August 10th. 1889. (Macoun.)

(439.) W. microcaulon, C. M. & Kindb. (p. sp.)

Resembling a small form of Webera polymorpha in the very short (about 3 mm. long) stem and the leaves acute, agglomerate in small buds. Differs principally in the dioecious inflorescence and the very large spores, unripe about 0.03 mm. The capsules (not ripe) are short-obovate, annulate, with a short neck and a low mammillate lid, the pedicel straight, arcuate at the apex, 1-1.5 cm. long, the comal leaves scarcely revolute at the borders, the inner perichetial much shorter. The tufts are very compact; the leaves green or finally blackish.
