Hab. On moist turfy banks, and decaying stems of trees. Killamey, 

 Dr. Lindberg. 



I have copied closely Dr. Lindberg' s description and synonymy 

 (Hepat. in Hiber. Lectse, p. 513) of this species, which I am not 

 well acquainted with, though Dr. Lindberg pointed it out to me, 

 growing near O'SuUivan's Cascade, Killarney, in 1873. It is 

 the plant figured by Hooker for Jung, multifida, in Brit. Jung. 

 (pro 2}(irte), and what Dr. Taylor and others, including myself, 

 have long considered that species. Hooker's var. f3., which 

 forms part of tab. 45, in Brit. Jung., is described as a species by 

 Dumortier, in Hepat. Europ., viz., Aneura sinuata, p. 142. 

 Although these are conspicuous plants, it is exceedingly difficult 

 to define their limits as species or varieties.

Hab. On the earth, in fields consisting of strong clay land which are 

 moist in vi4nter. On a wet clay bank at Collin Glen, near Bel- 

 fast, !Mr. David Orr. I have never seen any Irish specimens of 

 this plant, nor have I heard of it having been observed by any 

 other person than Mr. Orr in Ireland.
