Lees : Recent Moss Discoveries in West Yorkshire. 19 



to be done ; but tbe fungi, alg£e, lichens, and even the mosses, still 

 offer a good field for investigation. The West Riding moss list 

 includes 315 species as really occurring within the limits of the West 

 Riding, after the careful elimination of eight " Incognitis " included 

 in former lists on the slenderest grounds, and of six other species 

 whose localities are really outside the Riding, although also inadver- 

 tently finding a place in former lists ; 314 species out of the 570 

 now known for all Britain, is a large proportion to have, and shows 

 how relatively rich the West Riding is in mosses. 



The species discovered in recent years, and not included in any 

 former list, are as follows : — 



1. Sphagnum intermedium^ Hoffm. — Discovered first by Mr. John 

 Whitehead, 1870, afterwards found on Marsden Moors, near Redbrook, 

 by Mr. C. P. Hobkirk. 



2. S. papillosum, Lindb. — On the moorland between Slaidbum and 

 Clapham Station, at Rowland Knotts, by myself in company with Mr. 

 Wm. Todd, in 1876. 



3. Androea crassivervla, Bruch. — On the rocks of Penyghent, at 

 2000 feet, by John Whitehead, in 1868. " Hebden Bridge, 1865 " 

 (Hobk. Synopsis, p. 22) ; but although gathered prior to Mr. White- 

 head's discovery of it, it conld not have been determined until after 

 the publication of the list of West Riding mosses by Mr. Hobkirk, 

 in Journ. Bot., 1873. 



4. Weissia crispula, Hedw. — Discovered, and recorded only, by Mr. 

 Thomas Hick, B.A., B.Sc, on rocks near Harrogate, 1876. 



5. Tortula insulana, De Not,, cylindrica, Tayl. — Detected first by 

 Mr. C. P. Hobkirk, at Grimescar Wood, Huddersfield, in 1876. 

 Small fence of Harewood Park, near Leeds, 1871, gathered by myself 

 and n2LmQ^fallax, which it much resembles in facies. It is probably 

 not rare, but passed over SL?,fallax. 



6. Tortula intermedia, Brid. — First found by Mr. C. P. Hobkirk 

 on the banks of the Nidd, above Pateley Bridge. Slaidburn, 1876, 

 by myself, determined by Mr. Hobkirk.

 Hodder, above Slaidburn, in 1876, by myself and Mr. William Todd. 

 Determined as ovata by Mr. C. P. Hobkirk. 



8. Bryum roseum, Schreb. — Discovered by Mr. T. Stansfield, in 

 Pennant Clough, Hebden valley.
