ceasing below the toothed apex; sporangium oblongo-pyri- 

 form ; neck shorter than the spore-sac ; lid mammillary. 

 Hook. $ Wils. t. xlvii. ; Eng. Bot. t. K03. 



Scottish and Welsh mountains. Bearing fruit in summer. 



Differing from the last in inflorescence, the shorter more 

 clearly serrated leaves, the longer nerve, and the shorter neck. 

 There are no cilia in the inner peristome. 



3. W. elongata, Schwceg. ; monoicous ; upper leaves lineari- 

 lanceolate, erecto-patent, nearly straight, toothed at the apex ; 

 margin recurved below ; sporangium elongate-elliptic ; neck 

 longer than the spore-sac ; lid acute ; cilia none or imperfect. 

 Hook. $ Wils. t. xxx. ; (Moug. % Nest. n. 32.) 



On rocks, banks, etc., especially in alpine or subalpine dis- 

 tricts. Bearing fruit in summer. 



Gregarious or forming little tufts. Lower leaves scattered, 

 ovato-lanceolate, upper spreading or erect ; lid sometimes 

 almost rostrate. 



** Neck of sporangium short, membrane of inner peristome 

 broader ; cilia perfect. 



4. W. nutans, Hedw. ; monoicous ; upper leaves gradually 

 longer, lineari-lanceolate, toothed at the apex; sporangium 

 pendulous, ovali-pyriform ; lid mammillary. Hook, fy Wils. 

 t. xxix. ; Eng. Bot. t. 1240.; (Moug. $ Nest. n. 220, 1123, 

 1124.) 



On heaths, rocks, etc. Bearing fruit in spring. 



Forming green tufts. Stem reddish ; antheridia generally 

 in the axils of the leaves, but occasionally mixed with the 

 archegonia; ring large; nerve of leaves ceasing at or below 

 the apex ; cilia decidedly appendiculate, though Schiraper's 

 generic character would indicate the contrary. 



A most variable species.
