dry. Paraphyllia numerous roundish. Stem leaves densely crowded, 

 squarrose, slightly crisped when dry, broadly-triangular-cordate, more 

 longly and acutely acuminate, feebly sulcata, often twisted at point, 

 margin sharply serrate, nerve | the length of leaf; cells at base elongated, 

 at the strongly excavate angles small, quadrate and oval, the upper very 

 narrow ; leaves of branches similar. Perichsetium squarrose, inner 

 bracts suddenly narrowed into a recurved toothed subula of equal 

 length. Seta short and smooth, capsule cernuous, cylindraceous, 

 reddish-brown, lid rather shorter, peristome yellow. 



Hab. — On the ground and old walls in calcareous districts, rare. Fr. 12—2.

This moss differs totally in habit from striatum, and there do not appear

 S. France, Italy, Spain, Portugal, and Algeria.
