It often grows in broad patches or flakes on the inclined faces of rocks, 

 over which water occasionally flows." Wils.

On walls and stones. Fr. Oct. Nov. — The rostrate lid and concave 

 short-pointed leaves distinguish this species from its affinities. 



17. H. purum, Linn, (neat meadow Feather -Moss); leaves 

 closely imbricated oval with a very short point very concave, 

 the nerve reaching half way up, capsule ovate cernuous, lid 

 conical. Linn. Sp. PI. p. 1594. Hedw. Sp. 3Iusc.t.66.f. 3 — 6.

On the ground, on banks and in woods, abundant. Fr. Nov. — Dil- 

 lenius informs us that the specific name of this very common moss is 

 derived from the use, made of it in some parts of England, in cleans- 

 ing worms for Fishermen. 



18. H. piliferum, Schreb. (hair-pointed Feather -Moss); leaves 

 ovate with a long narrow acumen scarcely serrated, the nerve 

 disappearing below the middle, capsule cernuous, lid rostrate.

Banks, rarein/r. : found in that state at Auchindenny, near Edinburgh, 

 Mr. Arnott; and Cotteral wood, Cheshire, Mr. Wilson. Fr. Nov. — 

 A distinctly marked plant, which at the suggestion of Mr. Wilson I have 

 removed from the division with serrated leaves, where it has no affini- 

 ty, and placed along with H. murale and purum. The leaves of the stem 

 are exactly ovate and so suddenly acuminated into a long narrow 

 point, as to appear, especially when dry, to be hair-pointed. Those of 

 the branches are more gradually attenuated and scarcely warrant the 

 specific name.
