158 BRTACE^. [Glyphomitrlum. 



This species, the smallest of the genus, is distinct in its small size, the 

 obscure areolation in the upper part of the leaves, the cells hyaline and 

 hexagonal at the base, the well-marked neck of the capsule extending one- 

 third of its length, and the teeth united in pairs, entire or agglutinate their 

 whole length. 



52. GLYPHOMITRIUM, Brid. 

 Plants very small, simple or sjiaringly branched, tufted. 

 Leaves ovate and lanceolate, opaque ; perichsetium long, the 

 inner leaves sheathing nearly to the apex. Flowers monoecious, 

 axillary. Calyptra large, descending to below the base of the 

 capsule, many times split and plicate. Capsule globose, solid, 

 erect, on a somewhat long pedicel. Lid conical-acuminate. 

 Teeth of the peristome 16, lanceolate, very entire, approximate 

 in pairs, with hyaline borders. Annulus none. Spores large. 



1. Gr. Canadense, Mitten. Leaves lanceolate, tapering to 

 an acute or blunt point, the borders recurved from the base to 

 the middle ; cells oblong near the base, narrower at the angles, 

 gradually becoming round above ; perichaetial leaves very 

 broadly ovate, convolute, short-ajjiculate : calyptra rugose at 

 the apex : capsule oval, on a short pedicel 5 or 6 m.m. long. —

Hab. British America (Drummond). 



Resembles the European G. Damesii, but differs in the oval capsule, 

 the short pedicel, and the shorter stems. 



63. AMPHORIDIUM, Schimp. (PI. 2, as Zygodon.) 

 Plants soft, yellowish or dirty green above, black or brown 

 below. Leaves soft, carinate, crispate when dry. Flowers 

 monoecious or dioecious ; perichaetium sheathing. Calyptra 

 cucullate, small, fugacious. Capsule short-pedicellate, without 

 peristome, contracted under the orifice, urceolate when dry and 

 emjity. 



1. A. Lapponicum, Schimp. Monoecious: stems brittle, 

 2 to 4 cm. long : leaves lanceolate, acute, the upper longer, 

 spreading or curved back when moist, crispate when dry, 

 bright green when young ; costa vanishing below the apex : 

 male flowers in axillary sometimes aggregate buds : capsule
