plant to be a distinct species, and was discriminated ])y tlic Italian 

 botanist, Prof. Massalongo, from specimens collected in Italy by 

 Dr. Rossetti. 



Orii^inal specimens from Dr. Taylor of Loj. echinata comprise 

 both this species and Lcj. calcarna, but as Prof Massalonyo was 

 the iirst to recognise its distinctness, his name justly deserves to 

 be preserved. 



From other British Lcjeunecc it is at once separated by its 

 echinate leaves. 



Hab. — On limestone rocks, amongst mosses, and often inter- 

 mingled with L. calcarea, Lib. Rare.
