I58 THE FLORA OF HALIFAX. 



pale green cushions. It is rather like Milium hornum but 

 has a denser habit of growth. The plants are always male 

 or barren. Mr. Soppitt noticed it near Sterne Mill, in 

 in 1895, on the Norland side of the river. 



It was discovered as a distinct species in this district by 

 Nowell. In a paper " On Some Rare Mosses at Tod- 

 morden " read before the Todmorden Botanical Society, 

 March 1866, he says " The little known Atrichum 

 laxifolium Wils. M.S. = A. cvispum Sullivant, was first 

 brought into notice in this neighbourhood, either as a 

 curious form of A . undulatum, or a new species, but not 

 having been found in fruit here, it was not much noticed 

 until a Mr. James of New Jersey, North America, sent it 

 in fruit unnamed, along with other plants to Mr. Wilson, 

 having met with it in fruit in New Jersey. Mr. Wilson 

 made it out to be identical with our plant. Only the 

 male plant has yet been found in Britain. Dr. Schimper 

 says that it is new to Europe. It is found in nearly all 

 the rocky moorland streams in this district, and it has 

 also been found in similar places in Saddleworth, but I 

 have not heard of its being found further north than here."
