 och tillaeg. (1867). 



Dioicous; densely pulvinato-csespitose, deep green above, ferruginous 

 and tomentose at base, J — 2 in. high. Pseudopodia numerous, terminating 

 in a globose head of elliptic gonidia, each of 2 — 4 cells. Leaves erecto- 

 patent, linear-lanceolate, eroso-denticulate at apex, incurved when dry, 

 • margin reflexed in the lower half, nerve pale, vanishing and often 

 flexuose towards apex ; cells rounded, incrassate, with a papilla on each 

 side. Perich. bracts lanceolate-subulate ; caps, ferruginous, oblongo- 

 cylindric, erect, then cernuous, when dry and deoperculate, horizontal, 

 contracted, deeply sulcate ; calyptra reaching middle of caps., long- 

 beaked, lid large, convex at base, shortly conic ; peristome very pale 

 yellow. Male infl. terminal, gemmiform, bracts 12, linear-lanceolate. 



Hab. — Woods and shaded gravelly banks. Fr. 6, very rare. 



In fruit between Plumstead and Abbey Wood, Kent (Dillenius, Mitten 1843, Braitliwaite 

 1854) ! ! now destroyed. Dunmore Tower, near Airth, Falkirk (Lyle 1849) ! Valley of 

 the Churnet, Stafford {Dr. Eraser 1868) ! ! 



The numerous pseudopodia on this moss with their clusters of gemmae, 

 at once catch the eye, and no doubt afford a ready means for the increase of 

 the species. It is extremely rare in Ireland ; in Epping Forest it is frequent 

 in hollows in the trunks of pollard hornbeams. 



Sect. 2. TIMMIE.(E. Resembling Polytrichum in habit. Leaves from 

 an appressed sheathing base, lanceolate, the cells small, hexagono-rotundate. 



TIMMIA Hedw. 



Stirp. cr. i, 83 (1787). 



Stems simple, the leaves equal, sheathing at base, elongato- 

 lanceolate, serrate. Caps, ovate-oblong with a short neck, not striate ; 

 calyptra small, cucullate, peristome as in Mnium. — Der. after J. C. 

 Timm, of Malchin, in Mecklenburg. 



A small genus of pretty mosses of which two other species are found in 

 Europe, T. megapolUatut and havarica; all are very much alike in habit, which 

 quite resembles that of Polytrichum. 



Clavis to the Species. 



Leaf-base orange, widely sheathing, smooth at back. austriaca. 

 hyaline at insertion, scarcely sheathing, papillose at back, norvegica.
