On sandy banks of streams in woods. 



Tufts wide, dark green ; stems about I inch 

 high, sparingly branched, curved at the top. Leaves 

 convex towards the anterior margin. Dillenius 

 distinguished this from P. asplenioides. It may be 

 recognised by the obovate leaves, which have no 

 appearance of being truncate at the tips ; by their 

 being more crowded, nearly vertical, dentate 

 throughout ; by both their margins being recurved, 

 and thence appearing convex in front, by their less 

 patent position, by the greater length of their de- 

 current bases, very essentially by their smaller 

 cellules ; and by the mouth of the calyx having 

 large crenulations, which are themselves denticulate. 

 Besides the tufts are of a darker green, and the 

 shoots more slender. Taylor.
