Moist clayey banks, etc. Bearing fruit in spring. 



Forming loose tufts or gregarious; often throwing out 

 shoots from the base. Leaf-cells large, elongated; those at 

 the margin narrow; sporangium reddish. The large peri- 

 stome, wide leaf-cells, and peculiar fruitstalk, abundantly dis- 

 tinguish this from all the preceding species. 



b. Lower leaves ovate ; upper only lanceolate. 



8. W. Ludwigii, Schimp. ; dioicous, tufted ; stem decum- 

 bent ; lower leaves ovate, then ovato-lanceolate, obtuse, more 

 or less decurrent, finally lineari-lanceolate and toothed ; margin 

 slightly reflexed; fruitstalk very slender, geniculate at the 

 base ; sporangium pyriform, slightly curved ; lid small, con- 

 vex, apiculate. — Hook, fy Wils. t. xlvii. ; Eng. Bot. t. 2855.; 

 {Moitff. fy Nest. n. 831.) 



Tops of mountains of Scotland and Wales. Bearing fruit in 

 autumn. 



Forming broad, bright-green patches, reddish below. Dis- 

 tinguished from W. annotina by its broader leaves, differently- 

 shaped sporangium, and geniculate slender sporangium. The 

 stem is decumbent below the innovations, as in Bryum ; leaves 

 scarcely twisted when dry. 



9. "W. albicans, Schimp. ; dioicous, tufted ; stem erect or 

 decumbent at the base ; lower leaves distant, ovate, acuminate ; 

 upper lanceolate ; nerve ceasing below the toothed apex ; spo- 

 rangium shortly pyriform ; ring none ; lid small ; peristome 

 large.— Hook. §■ Wils. t. xlvii. ; Eng. Bot. t. 1527, 2272, 

 2836.; {Moug. $ Nest. n. 1125.) 



Wet banks, dripping rocks, etc. Bearing fruit late in the
