THE FLORA OF HALIFAX. I3I 



FILICES. 



Hymenophyllum tunbridgense, Sm. — 28. Filmy Fern. 

 Native. Atlantic type. P. June-July. 



1835. Found on Langfield Moor, near to Studley Pike by 

 John Howarth, of Lob Mill ; 1837. Rake Hey Common, 

 near Todmorden. — Herb. Leyl. 



1844. Near Halifax. — W. Wilson, Phytologist, i. 453. 



1854. Mr. Wilson has found it near Halifax, . . . and the 

 late Mr. Gibson, near Todmorden. — Newman, Brit. Ferns. 



No recent record of it, but as the exact localities are unknown, 

 and Rake Hey or Langfield has been but little examined, 

 and not at all for this fern, it may be still existing. 

 Hymenophyllum unilaterale, Bory. — 47. Filmy Fern. 

 Native. Atlantic type. P. June-July. 



1834. Turner Clough. — Herb. Leyland. 



1838. Turner Clough. — 5. Gibson. 



Records by Baines, Wilson, Newman and Watson, in some 

 cases authenticated by specimens, refer to the same locality, 

 but it does not appear to have been found there for the 

 last quarter or even half century. Still the locality is by 

 no means deteriorated botanically, except at one end, and it 

 is not at all unlikely that a careful investigation might 

 reveal either one or both of the filmy ferns existing there.

Native. British type. P. July-September. 



1785. About the skirts of barren moors. — /. B., Fil. Brit.
