WEBERA. 311 



spreading and little altered in direction, widely ovate-lanceolate, 

 acute, upper longer, narrowly ovate-lanceolate, from a narrow, 

 slightly decurrent base ; thin, pellucid, margin plane, denticulate 

 in upper half ; nerve vanishing below apex ; cells rhomboid- 

 hexagonal, rather large, 15-20 /x wide, slightly narrower towards 

 margin, hardly altered at base. Seta tall, flexuose, slender, 

 about f-i inch long, hooked at summit a little below the neck of 

 the capsule, which is pendulous, shortly and widely pyriform, 

 larger than in W. carnea, greenish until ripe, then brown or 

 reddish, wide-mouthed when dry and empty; annulus none; 

 peristome teeth pale brownish yellow, cilia 1-2, long. Dioicous. 

 Male flower large, terminal, discoid ; perigonial bracts widely 

 spreading. 



Var. /3. glacialis Schp. (Mnium glaciate Schleich.). Taller, 

 more robust, with more distant, wider leaves, of a duller green. 



H ab. Clay banks, springs, mountainous streams, etc. , frequent. The var. $ on 

 high mountains. Fruit not common, produced in spring or early summer. 



A very beautiful plant, known at once by its pale glaucous green tufts, hardly re- 

 sembled by any other of our mosses, though slender forms of W. cruda are sometimes 

 like it in habit, and in its stunted forms it is not unlike W. carnea ; the narrow cells, 

 rigid texture, etc., of the former would at once distinguish that species, while W. 

 carnea almost always has narrower, firmer leaves, of a greener colour and less pellucid. 

 The male flowers are very conspicuous. 



The var. glaciale in its typical form is a fine and distinct plant, and is very rarely 

 fertile ; intermediate forms however are common, and indeed the plants that are 

 found in and about mountain streams generally show some approach to this variety. 



C. EPIPTERYGIUM. 



Leaves dimorphous, the larger somewhat distichous, widely 

 oval, the others minute, in two or three rows, alternately with the 

 former ; areolation lax, marginal cells in 3-5 rows suddenly 

 narrower, forming a distinct border. Dioicous. 



10. Webera Tozeri Schp. {Bryum Tozeri Grev. ; Epi- 

 pterygium Tozeri Lindb., Braithw. Br. M. Fl.) (Tab. XLII. I.). 



Plants small, soft, densely gregarious, rarely £-inch high, 

 pale green or reddish ; stems red, slightly branched. Leaves 

 rather distant, of two forms, especially on the male plants ; the 

 smaller minute, narrowly ovate or lanceolate ; the larger widely 

 oval or obovate-rounded , very shortly and acutely acuminate or 

 almost apiculate, slightly decurrent, very narrow at base, thin, soft, 

 pellucid, entire, plane at margin ; nerve reaching about f length
