HAB. Scotch, Welsh, and Irish mountains. 



It is not without some hesitation that we have ventured to 

 quote under our present plant the Tr. funale of Sehwaeg- 

 richen, which we have received from Ireland from Mr. 

 Templeton. It must however be very apparent upon an 

 inspection of Schwaegrichen's figures that the two only 

 ,j .. differ by the one having hair- pointed leaves and a striated 

 capsule. Now, not only in our Scotch specimens of Tr. 

 patens have we observed the capsule when mature to be 

 furrowed, but Wahlenberg supports us in this observation, as 

 appears in his description of the moss as it is found in Lap- 

 land. As to the points of the leaves, these we have found 

 piliferous in specimens which we have collected on the Swiss 

 alps. We have ourselves gathered Dillenius' plant on Snow- 

 don, and compared it with the specimens in his herbarium, 

 and find them to accord entirely with Tr, patens. The 

 fruit is apparently lateral from an elongation of the stem. 



** Fruitstalks straight. 

 f Leaves with diaphanous points. 



2. Tr. lanuginosum ; stems elongated, subpinnate ; leaves lan- 



ceolato-subulate, acuminate ; their long diaphanous points 

 serrated, margins recurved; capsule ovate ; fruitstalks short, 

 on lateral branches ; lid rostrate. (TAB. XIX.)

HAB. On mountains, especially at some considerable ele- 

 vation. It has likewise been found on the flat heaths in 

 Norfolk by the Rev. James Lay ton. 



This species, very common in mountainous countries, can 

 scarcely be mistaken for any of its congeners. The stems 

 are sometimes a foot or more in length, and have an irregu- 

 larly pinnated appearance ; and the fruitstalks, without an 

 attentive observation of the branches on which they stand 

 terminal, may be taken for lateral.
