Dioicous ; tall, robust, in rather dense tufts, yellowish green above, 

 ferruginous at base. Leaves from a reddish brown sheathing base, 

 suddenly lineal-lanceolate, rather glossy, erecto-patent, biplicate, when 

 dry incumbent, subarcuate and convolute-concave above, the margin 

 coarsely serrate, nerve serrate at back of the rather obtuse apex, cells 

 linear at base, quadrate and incrassate above. Perich. bracts shorter ; 

 caps, horizontal, on a long seta, longish oval, reddish-brown, faintly 

 striate, furrowed when dry ; annulus broad, triple, lid orange-red, 

 hemispherical with a small point ; teeth yellowish-white, papillose, those 

 of endostome not appendiculate. Male plant resembling the female, 

 the leaves more divaricate, bracts patent. 

 HAS. Rocks and stony places on mountains, very rare, sterile. 



Rocks by the Isla, above Airly Castle, Forfarshire (Drummond 1824)! Ben Lawers 

 (Wilson 1858) ! Craig Mhor, Glen Lochay (Grieve 1888) ! ! 



Timmia megapolitana HEDW. is smaller, autoicous, the leaf-base less 

 sheathing and papillose at back, the processes of endostome with prickle- 

 shaped appendages ; it has been recorded from Ben Lawers, but all the 

 specimens I have seen so named belong to the next species. 



2. TIMMIA flORVEGICA Zett. 



Dioicous; leaves not sheathing, having a band of thin hyaline 

 cells at their insertion, serrate in the upper half. (T. LXXX, E.)
