THE Hypnum purum has been confidered as producing its Fructifications but fparingly, yet if it be examined 

 at the proper feafon of the year viz. in the month of November, the period of its greateft perfection, it will not be 

 found deficient in this refpect, at that time its leaves are of a bright green colour, but as the plant advances they 

 change to a yellower hue than moft others. 



Dillenius makes no mention of the Calyptra belonging to this mofs* from whence it would appear that like 

 molt other Botanifts he examined it at too late a period ; in general thofe Capfules which have a mort Operculum 

 carry the Calyptra but a little while, as in the prefent plant, while thole in which the operculum is long bear it 

 often to the falling off of the operculum itfelf as in the Bryum undulatum. 



This is one of the molt general Mofles we have, growing in woods, in paftures and by hedge fides univerfally, in 

 the former it is moft frequently found with its capfules, the oak of Honour Wood and the woods adjoining pro- 

 duce it in this ftate at the time above mentioned in the greateft plenty ; being a mofs generally free from all impuri- 

 ties it is made ufe of by the anglers in Lancashire and probahly in other counties to fcour their worms in. Dill.
