On mountains, abundant; rare on heaths in the plains ; as in Norfolk, 

 Rev. James Lay ton. — The stems are sometimes a foot or more in length, 

 and have an irregularly pinnated appearance. 



4. T. canescens, Hedw. (Jwary Fringe-Moss); stems elon- 

 gated irregularly branched, leaves ovato-lanceolate their dia- 

 phanous acuminated points slightly serrated, capsule ovate, teeth 

 of the peristome very long and filiform, lid subulate. Hedw. St.

On heaths and stony places in mountainous countries, frequent. Fr. 

 Winter and Spring. — The /3. though very different at the first aspect, 

 can scarcely be considered otherwise than as a var. of the present, 

 having numerous short pinnated branches. 



5. T. heterostichum, Hedw. (serrated hoary Fringe- Moss); stems 

 elongated branched, leaves ovato-lanceolate their diaphanous 

 points slightly serrated, capsule cylindrical, teeth of the peri- 

 stome rather short, lid rostrate. Hedw. St. Cr. v. 2. p. 25.

On stones, in mountainous districts. Fr. Spring. — Similar as are the 

 Stems and foliage of the present plant to the last, yet the fruit is very 

 different, the capsule being much narrower and longer, the teeth are 

 shorter and almost resemble those of a Dicranum, but are more deeply 

 cleft. 



6. T. microeurpum. Hedw. (siuull-fiuited hoary l'ringe-Moss); 

 stems elongated branched, leaves lanceolate their diaphanous 



acuminated points slightly serrated, capsule ovate teeth of the 

 peristome rather >hort, lid rostrate. Hedu\ Sj>. Muse. t. 28.

On rocks. Fr. March. — Sometimes all the tip-, of the /inns are 



coloured ; ami w hen that i- the case ami the plant is Bmall, it corresponds 



probably with Mr. Turner's Dicranum aeiei.lare, y. Whether our plant 



be thai of Hedwig, 1 am doubtful; for the capsules figured in the Sp.
