"Mr. Mitten detected this fine species in a collection made many 

 years ago by the late Miss Hutchins in the soutli of Ireland. It is 

 abundantly distinct from either F. punctata Tayl., or P. spinulosa Dicks., 

 to which it is most nearly allied " : Pearson 1902. My search for this 

 fine Plagiochila has not met with success, though I am well acquainted 

 with the plant, having studied a specimen sent to me by Mr. Mitten.
