REPORT ON THE BRYOLOGICAL FLORA 

 OF YORKSHIRE FOR THE YEAR 1897. 



J. J. MARSHALL, 



Bryological Sec7eiary to ike Botanical Sectio>i of the 

 \'orkshire Nattiralists Ihiioii . 



It is very gratifying to find that the sustained interest and successful 

 work on the part of Yorkshire bryologists during recent years has 

 given occasion to your executive to propose the formation of a new 

 committee to further research in this branch of botanical knowledge. 



The arrangement for a bryological foray in connection with the 

 annual meeting is also a subject for congratulation amongst your 

 members. It occurs at a season when large numbers of mosses are 

 in a state of perfection, and also at a time when little or no oppor- 

 tunity has been given to j'our members for combined investigation 

 of the moss flora of the county. 



Several extremely interesting additions have been made to the 

 Yorkshire moss flora during the past year. The most unexpected is 

 Jnlnila Hufchinsite, an Irish hepatic, discovered by Mr. Jas. Needham 

 near Hebden Bridge. It was first found by Miss Hutchins in the 

 south of Ireland, and has since been gathered in several places on 

 the west coast of England, Wales, and Scotland. It is very remark- 

 able that within a few weeks Mr. L. J. Cocks, of Harrogate, should 

 discover another Yorkshire locality, viz., Ravengill, near Pateley. 



Mr. W. Inghaip, B.A., of York, has added many varieties of 

 mosses to the Teesdale records, as well as several new to the vice 

 counties. His best find is Ceratodon conicus, believed to be the first 

 record for Yorkshire. He has discovered two stations for it, one 

 during the Hackness excursion and subsequently at High Force, 

 both in fine fruiting condition. His list also includes : — Polytrichum 

 gi-acile, Cynodoiitium Briaifoni, Campylopus atrovi7'ens, Totiit/a 

 lamellata^ Bryiim concinnatum, Brachythechim ccespitosum, Hypinitn 

 ochraceum var. flaccidum^ and H. giganienm on Skipwith Common 

 (new to the East Riding), and many other good plants. 



Mollia calcarea, a very rare British moss, is also new to the 

 county. It is recorded by Mr. Cocks from KnaresborcHigh, the 

 only previous British habitat being Cheedale in Derbyshire, where it 

 >vas found by Mr. W. West in 1880.
