nerve strong, ending in the point. Paraphyllia lanceolate, branched, 

 ciliate. Branch-leaves from a broadly ovate concave base, suddenly 

 acuminate ; ramuline leaves longish-pointed, nerved half way, the cells 

 longishjthe apical one lunulately truncate, crowned by 3 — 4 acute papillae. 

 Inner perich. bracts plicate, not ciliate, eroso-dentate at apex, lanceolate, 

 gradually acuminate into a long, serrulate loricate subula. Caps, nearly 

 erect, cylindric, light brown, on a red-brown seta, the lid more shortly 

 rostellate. Annulus of 3 rows of cells. Peristome as in 7. delicatuhim . 

 Male plant small and but little branched, and frequently the male infl. is 

 found nidulant on the female plant. 



Hab. — Woods and banks in calcareous districts. Fr. very rare, 7 — 8. 



Romantic rocks, Matlock Bath (Smith 1790, c. fir.). Helk's wood, Ingleton {Wilson 1838, 

 c. fr.) ! ! Sterile plant not uncommon. 



This moss is pretty generally distributed, and is often of a yellow shade, 

 the branches are shorter and more obtuse than in T. tamarisci folium, from 

 which it may easily be distinguished by the apical cell of the ramuline leaves. 



Sect. 2. TETRATHAMNIUM Mitt. Stems ascending, pinnate, the 

 branches arranged in two rows on each side of stem, one of each pair being 

 anterior, and the other posterior.

Dioicous ; stems rigid, pinnate with attenuated branches. Leaves 

 densely imbricated, erecto-patent, ovate-acuminate, nerved nearly to 

 apex, cells rounded, papillose. Caps, subcylindric, cernuous.
