Since the publication of the first edition, we have met with 

 a Trichostomum, which, different as it may appear at first 

 sight from T. patens, we are yet unable to separate from it 

 specifically. This is the var. ft. above mentioned, correspond- 

 ing in every respect with the T. funale of Schwaegrichen, 

 except that the lid is rostrate. With regard to the more general 

 appearance of the plant, the original specimens of Dillenius and 

 Dickson accord precisely with our variety a. majus ; especially 

 in having a sulcated capsule, thus differing from that of 

 Schwaegrichen, which is both figured and described "theca 

 laevi." This we have never observed ; we know, however, that 

 the T. incurvum of Hoppe and Hornschuch is precisely our T. 

 patens. 



In specimens sent by Mr. Drummond, the capsule is longer, 

 sometimes striated, and sometimes smooth. 



* * Fruitstalks straight. 

 f Leaves with diaphanous points. 



2. T. lanuginosum ; stems elongated subpinnate, leaves lanceolate- 

 subulate acuminate their long diaphanous points serrated, 

 margins recurved, capsule ovate, fruitstalks short on lateral 

 branches, lid rostrate. (TAB. XIX.)
