ADDITIONS TO THE MOSS-FLORA OF YORKSHIRE. 



WILLIAM INGHAM, B.A., 



Organising Inspector of Schools, 4.J, Haxby Road, York. 



liypnum Schleicheri Hedw. fil., of the ' British Moss Flora,' or 

 Eurhynchium abbreviation Schp. This moss I found on 

 a stiff clay bank in a spot that is always in shade, near 

 Healaugh, Tadcaster, 16th November 1899. 



Mr. Dixon calls it an interesting find, as it has hitherto 

 been considered a southern moss only. I have specimens 

 from Sussex, Gloucester, and Hereford, and I am pleased 

 to add a fourth from the north of England. 



liypnum Schleicheri var. rigidutn Boul. This I found near 

 Kirkdale Cave, 22nd May 1899. It is very distinct from 

 type in its rigid and upright growth and pale colour. 



Mr. Dixon sent me Hypnum (Eiirhynchiuvi) Swartzii 

 Hobk., var. rigidum Boul., from Bonchurch, Isle of Wight. 

 My gathering has the long and narrow areolation of 

 H. Schleicheri, whereas Mr. Dixon's has the wider and 

 shorter areolation of H. Swartzii, but in habit they are the 

 same. 



Weisia calcarea var. viridula CM. This moss I found in the 

 Castle Howard Wood, 18th May 1900, in the presence of 

 Dr. Braithwaite, and Mr. Slater of Malton. The only record 

 of this moss hitherto has been the very vague and unsatis- 

 factory one of ' Scotland.' 



Dr. Braithwaite writes that my naming is quite correct. 



The type TV. calcarea has been recorded already in 'The 

 Naturalist' from Knaresborough, where I also found it 

 independently on 7th June 1898. 

 Weisia crispata CM. In the Jackdaw Crag Quarry, Tad- 

 caster, 21st January 1898. This must be the moss men- 

 tioned by Mr. Marshall in the August number of ' The 

 Naturalist' under the name of Mollia crispuld Lindb., which 

 is a very different moss from the new one, W. crispata 

 CM. I have found Mollia crispata Lindb. in several places 

 in Yorkshire and Durham, and I regard it as a common 

 moss. 



I have found W. crispata CM. also in Durham, by the 

 side of Kilhope Burn, and it is an addition to the Moss 

 _ Flora of Durham. Verified by Mr. Dixon.
