Grows in very compact masses of a grass green on the sur- 

 face, but the lower parts of the stems are matted together 

 with a white calcareous incrustation. It does not produce 

 fruit in the above stations, but I have had the pleasure of 

 gathering it in a very perfect state in the romantic dean 

 at Twizel-house, the seat of P. J. SELBY, Esq. which is 

 only a short distance beyond our limits. 



3. W. recurvirostra, stems simple or branched ; leaves patent, 

 linear-subulate, carinate, entire, strongly nerved ; fruitstalks f ths 

 of an inch high ; capsule cylindraceous, slender, erect, with a co- 

 nical slightly inclined lid. Grimmia recurvirostra, SM. FL Brit. 

 1190. 



Hab. On sandy banks. On a moss-grown wall at the road- 

 side, a little west of East Ord, abundant. Winter. 



In habit resembles the Tortulce, and is altogether very much 

 like some of the varieties of Tortula fallax.

l.C. fontinaloides, dark-green ; stem much branched ; leaves 

 lanceolate, entire, strongly nerved, crisped when dry ; capsules 

 oblong, subsessile, on short lateral branches Trichostomum fon~
