YORKSHIRE 



HEP ATICiE. 



By W. H. Pearson, Manchester. 



The following notes are taken from Dr. Carrington's work on the 

 British Hepaticse, which is now being published, and as the 

 book is probably beyond the reach of many, these notes on the 

 Yorkshire stations may be useful to working naturalists. 



Scalius Ilookeri. Gray and B. — A very rare and local species, first 

 discovered by C. Lyell, Esq., is recorded from Barnaby Moor, near 

 York, by R. Spruce, 1842. It fruits in summer. 



Nardia ac^ws^a.— Recorded from Castle Howard, by R. Spruce. 



Nardia compressa. Gray and B. — Gathered by the late John 

 Nowell, at Todmorden, but whether on the Lancashire or Yorkshire 

 side of the Calder I cannot determine : from the moors on the west 

 side of Ingleboro' it has been collected ; the leaves are pellucid, and 

 tinged either purple or claret colour, always growing near water- 

 courses. 



Nardia ohovata. (N. ab E.) — Often overlooked for Nardia 

 hyalina. — Kildale, North York, W. Mudd, grows forming compact 

 tufts of a deep green colour, and producing abundant fruit in early 

 summer : damp rocks. 



Nardia hyalina. Lyell. — Fruits in early summer, and forms more 

 or less depressed tufts on wet slaty rocks or intermingled with bog 

 mosses ; it is remarkable for the crystalline glaucous green semi- 

 pellucid foliage and reddish rootlets. The late G. E. Hunt found it 

 at Hebden Bridge, and it has been collected from alum shale, at 

 Whitby, also at Ingleboro'. 



Trichocolea tomentella. Dumort. — Is one of the noblest and 

 most interesting of our native Hepaticae, reminding us of some 

 tropical types, and not likely to be confounded with any local species. 

 It grows abundantly in Bolton Woods, where it has been gathered in 

 fruit. 



Saccogyna viticulosa. Dumort. — The fruit of which is exceedingly 

 rare, has been gathered near Todmorden. 



HarpantJms smtatus. Spruce. — Grows in dense, compact tufts on 

 rocks or decayed trunks of trees, is found on rocks near the Strid, 

 Bolton woods,
