44 Yorkshire Natiiyalisis' Union : Annual Report, 1917. 



Reports of orchards vary somewhat, but a general agree- 

 ment is that this has been a pear year. 



No records of new plants are to hand, but confirmations 

 of old observations as Trientalis Europcea, Ilkley Moor, near 

 Helwick, 1677, vide Lees' ' Flora,' still there (J. Beanland) ; 

 Carex axillaris and C. pseudo-cyperus, near Hull, doing well 

 this year (J. F. Robinson) ; new localities for Riimex alpinus, 

 are GuyscUff, Nidderdale and Cookridge, Airedale (Sanderson 

 and Cheetham). 



Mr. W. B. Haley sends a note on the Dewsbury aliens, 

 which is added to the report of the botanical sectional meeting. 

 At the meeting of this Section held at Leeds, in October, 

 Dr. F. Arnold Lees showed fronds of Holly fern collected near 

 Settle this year ; it is good to know that this plant still grows 

 in our area. He also showed the Galium mentioned in his 

 note on page 328 of the October Naturalist. Mr. J. Beanland 

 showed a gathering of thi?; plant from Hubberholme, which 

 carries it much liigher up the river. 



Botanical Survey Committee. — Mr. W. H. Burrell 

 writes : — At Huddersfield Dr. Woodhead has been engaged in 

 tracking glacial deposits, with a view to establishing a founda- 

 tion for the origin of the local flora. A report of his work 

 was published in The Naturalist for July, pp. 219-232, and 

 further instalment showing the influence of these transported 

 subsoils on the vegetation of the Colne and tributary valleys 

 will be looked for. During the year the Doncaster Scientific 

 Society has been working at the Natural History of Martin 

 Beck, and a botanical survey of the wood is being carried out. 

 The progress of the work was sketched by Dr. Corbett at the 

 annual meeting of the Botanical Section, and details will be 

 published in due course. 



The study of the Ling covered areas of the limestone at 

 Moughton is being continued. A series of microscopic slides 

 showing seeds and organic debris from the lowest layers of 

 peat was on exhibition at Leeds on October 6th. 



Bryology. — Mr. W. Ingham, B.A., writes : — During the 

 past year has been published the ' Synopsis of the European 

 Sphagna,' by J. A. Wheldon, based upon Warnstorf's Sphag- 

 nologia Universalis. In this work are many records by myself, 

 of which a few are appended : — 



Sphagnum fimbriatuni var. validus (Wheeldale), var. laxi- 

 foliuni (Arncliffe Wood) ; 5. Girgensohnii v. robustum (Black 

 Hambleton) and var. microccphalitm (Wheeldale)'; S. Russowii 

 var Girgensohnioides (Reeth) ; 5. pliimolosum var. late-virens 

 (Buttercrambe Woods) ; 5. compactiim var. isophylla (Sandburn 

 Wood) ; 5. squarrosuni var. Spectabile (Buttercrambe Woods) ; 

 5. parvijolium vars. WarnstorfU and Inghami (Fen Bog) ; 5.
