130 ON THE SPECIES OF TIMMIA. 



unequally coarsely serrate, the nerve vanishing in the extreme apex ; 

 cells of base linear, upper quadrate, incrassate, almost empty ; 

 very minutely papillose on the upper part of back of leaf. Bracts 

 of perichaetiuni longly sheathing. Vaginula longly and narrowly 

 cylindric. Capsule sulcate when dry. Lid hemispherical or very 

 shortly conical. Annulus broad, triple. Teeth of outer peristome 

 rugulose at apex, and densely papillose, those of internal strongly 

 papillulose. Spores rufous-yellow. Calyptra long, narrow, mem- 

 branous, cleft above the middle, straw-coloured, brown at apex, 

 quite smooth. 



Male plants either forming separate tufts or growing in the same 

 with the female, very like the female, but with the leaves patent 

 divaricate. Andrcecium terminal, perforate from the growing point 

 of the stem as in Polytrichum (sometimes eccentricj ; bracts very 

 like the leaves, but patent; antheridia 6-10 times longer than the 

 thickish filament, equalling the paraphyses. 



Obs. This plant in habit is almost like Polytrichum juniperinum 

 or P. commune, and is erroneously stated by authors to be monoi- 

 cous, for we have always found the male organs in separate plants. 

 2. Tiznmia Bavariaca. Hessler. 



Autoicous ; green above, softened with great difficulty ; with a 

 rather tall dense-leaved stem ; the leaves of equal length, solid, 

 curling slightly when dry, from a scarce semi-vaginant yellowish 

 base, whitish and glossy when dry, patenti-recurved, gradually 

 lineari-lanceolate, very acute, scarcely plicate, the back of the nerve 

 smooth ; bracts slightly shorter ; seta slender, about 1^ inches 

 long ; capsule oval or elliptical horizontal, smooth ; lid hemisphe- 

 rical, most frequently impressed at the centre, and mammillate ; 

 annulus rolling back ; inner teeth pale yellow, spinuloso-appendi- 

 culate ; antheridia cylindric, from somewhat shorter to one half 

 longer than the longly obconical filament.
