26 Yorkshire Naturalists' Union : Annual Rport, ^1911. 



' T-esponsible. At none of the appointed excursions has the subject 

 been neglected, and good results have rewarded investigators ; 

 whilst many of the affiliated societies can show a good year's 

 work. We note that the veteran, Mr. J. G. Baker, is still adding new 

 species and new stations to his North Yorkshire Flora ; whilst in 

 the East Riding a new station for an almost or entirely extinct 

 plant, Schcenus nigricans, has been discovered at Kellythorpe,. 

 near Drifheld, where it grows plentifully, with abundance of 

 Carex paniculata and Lastrcea thelypteris. Dr. Lee's recent 

 supplemental list for the West Riding is further evidence of 

 our initial statement. 



Botanical Survey Committee. — Interesting observations on 

 vegetation problems have been made by members of the committee 

 during the year, and on the excursions increasing interest is being 

 taken in this line of work. It is hoped in the near future means 

 may be found to publish the results obtained, and also to establish 

 Yorkshire Survey work on a still more definite basis. 



Bryological Committee. — Mr. W. Ingham reports :— Mr. J. J. 

 Marshall has added Tortilla vahliana, Bryum warneum, and Bryum 

 torquescens to the Lincolnshire Flora. 



W, Ingham found Tetraplodon mnioides, Polytrichum commune 

 var. perigoniale, and Hypnum fluitans var. J eanhernati at the 

 Castleton meeting of the Yorkshire Naturalists' Union ; also 

 Swartzia montana var. compacta on Ingleboro' at the Yorkshire 

 Naturalists' Union meeting ; the only other Yorkshire record 

 for this distinct variety being by the Clough River at Sedbergh, 

 also by W. Ingham. 



Mr. C. A. Cheetham adds that he obtained Zygodon lapponicus 

 B. and S., and Th. philibertii as additions to the Yorkshire Flora, 

 from Ingleton ; and from the same locality, Grimmia torquata, 

 previously found in the county, at White Force, Teesdale, only. 



Mycological Committee. — Mr. C. Crossland writes : — The 

 fourth series of additions to the known Yorkshire fungi since 

 1905 was published in the April issue of " The Naturalist.". 



The Rev. Canon W. Fowler, Mr. Cheesman, and the writer 

 represented the Committee at the Yorkshire and Lincolnshire 

 joint excursion to Barton-on-Humber (" Naturalist," August, pp. 

 294-5) ; Messrs. M. Malone and J. W. H. Johnson at the Ingleton 

 Excursion, where ten additions were made to the North-West 

 Division (" Naturalist," September, p. 326) ; Messrs. C. H 

 Broadhead, W. E. L. Wattam, and Mrs. Whiteley, reported on 

 the fungi seen at the Huddersfield Excursion (" Naturalist," 

 October, p. 366). 



An unofficial foray was held at Sandsend for Mulgrave in 

 May, the results of which are added to the Annual Foray in the 

 same district in September (" Naturalist," November, pp. 337- 

 393). It will be seen that of the 488 species collected, 138 are addi- 

 tions to the Sandsend and Mulgrave districts, of these 45 are new
