crowded and fragile ; in a dry state irregularly incurved, with a 

 strong, whitish, very shining nerve, very prominent at the back, 

 the large hyaline cells of the leaf-base not well defined in the 

 centre from the upper small indistinct ones, but gradually be- 

 coming fewer as they ascend obliquely to end in the margin, 

 precisely as we find the areolation in all the Tortulce tortuosce ; 

 and, indeed, it is no doubt most related to Tortula inclinata, 

 Hed. f., but very distinct from it and all other species of the 

 same group. 



It appears not to be rare (on limestone ?) in the west and 

 south of Europe, and North Africa, as the localities cited will 

 prove, but has not yet been found in a fertile state.
